Introduction

The TxPORT PRISM

3001 (Figure 1-1) is a modular, single port, fractional T1

CSU/ DSU. The unit allows connection of high-speed digital data to a T1 facility. V.35- or EIA530- compatible high-speed port interfaces are available which support port rates from 56 kbps to 1.536 Mbps. The interface to the T1 network is made through an integral ESF CSU which provides full performance

monitoring of the T1 span and is compliant with T1.403,

TR62411, and TR54016.

The unit is available with a second DSX1 level T1 interface to support drop and insert applications. Network bandwidth may be allocated as needed between the high-speed data port and the T1 DTE port, allowing the integration of data and voice traffic across a single T1 facility.

The TxPORT PRISM 3001 provides the powerful feature set of the multiport TxPORT PRISM 3000 in one of the most compact packages in the industry. The 3001 module can be installed in either a single unit housing or in the 1051 -2 nest mount chassis which holds up to twelve units. Power supplies are available to meet the requirements of small to large installations, including full redundancy.

1-2 GENERAL

The unit may be controlled through a VT100 terminal or a computer with ANSI terminal emulation software. If used with the EM8000 Element Manager or 8100A Site Controller, the entire T1 network can be monitored and controlled from a central location.

LED indicators are provided on the front panel of the unit to alert local personnel of alarm conditions, loop and test status, and DTE port activity. A test switch allows local and remote loops to be activated as well as BERT tests. Although all configuration parameters are software selectable from the terminal interface or the network manager, configuration switches are provided on the unit to allow

operation without the use of a management interface.

NSTALLATION

Introduction

This chapter contains information and instructions required to prepare the TxPORT PRISM 3001 for use. Included are initial inspection procedures, mounting

instructions, configuration guidelines, connection instructions, and powering information.

Throughout this manual, all factory default settings are shown underlined.

Safety

Summary

This manual contains information and warnings which must be followed to ensure safe operation and to retain the equipment in a safe condition.

The WARNING sign denotes a hazard to the operator. It calls attention to a procedure or practice which, if not correctly performed or adhered to, could result in injury or loss of life. Do not proceed beyond a WARNING sign until the indicated conditions are fully understood and met.

Follow proper ESD (electrostatic discharge) procedures while handling the circuit boards.

Unpacking

and

Inspection

This unit is carefully packaged to prevent damage in shipment. Upon receipt, inspect the shipping container for damage. If the shipping container or cushioning material is damaged, notify the carrier immediately and make a notation on the delivery receipt that the container was damaged (if possible, obtain the signature and name of the person making delivery). Retain the packaging material until the contents of the shipment have been checked for completeness and the instrument has been checked both mechanically and electrically.

If the contents of the shipment are incomplete or, if there is mechanical damage or defect, notify TxPORT. If the shipping container is also damaged, or the

cushioning material shows signs of stress, notify the carrier of the damage as well as TxPORT. Keep the shipping materials for carrier’s inspection. TxPORT will arrange for repair or replacement without waiting for claim settlement.

Supplied

Materials

The PRISM 3001 is shipped from the factory with the PRISM 3001 reference manual.

The following additional materials may be required for the installation and operation of the PRISM 3001.

-48 VDC power source

Network and DTE interface cables

✦ 20-gauge stranded wire (or similar) for DC power and alarm connection

(16)

2-2 INSTALLATION

For specific applications, additional cables and adapters may be required. The interface requirements of any application may be met by using the appropriate cable. Contact TxPORT for any needed assistance in cable selection.

Mounting

The 3001 is a modular unit that plugs into either a single unit housing or into a chassis that holds up to 12 units. Single units are designed for stand-alone desktop use, wall mounting, or chassis mounting (in either a vertical or horizontal

orientation). The 3001 uses an interchangeable front panel to accommodate the chassis card cage.

Stand-alone Unit

To access the circuit boards and configuration switches, perform the following procedure. Observe proper electrostatic device handling procedures while holding the circuit boards.

1 Open the front panel access door and remove it by gently bending the plastic from the middle using both hands.

2 Pull the two side strips of plastic from the middle outwards until the four stops are clear of the front panel.

3 Pull the cover off the front panel.

4 Remove the two screws and pull the front panel and circuit boards out of the housing.

The stand -alone unit may be used in a chassis installation with the following modifications.

1 Remove the housing as described above and then remove the four screws holding the front panel to the circuit boards.

2 Replace the stand -alone front panel with a module type front panel. The unit can now slide into one of the 12 slots in the chassis.

Chassis Assembly

Up to twelve PRISM 3001 units may be inserted into a chassis and the chassis may be installed into a 19- or 23-inch rack using four screws. Connections are made from the rear of the chassis (refer to the illustrations on page 2-9).

The PRISM 3001 can be software configured in the same manner as the multiport PRISM 3000 by using a terminal connection to either the front panel Supervisory access port or the rear panel NMS IN port. The TxPORT EM8000 Element Manager and 8100A Site Controller may also be used to configure the unit by using the same ports. The terminal interface, element manager, and site controller provide a broader set of capabilities than by using the configuration switches. The 3001 provides non-volatile memory retention of unit configuration in the event of power failure. This feature allows the unit to automatically restore normal service following a power loss. Note, however, that when the unit is stored without power for an extended period, the battery may drain and some parameters may become corrupted.

(17)

Unit Configuration 2-3

Therefore, when the unit is first received for installation or if power has not been applied for an extended period of time, the configuration should be verified using either the terminal interface, element manager, or site controller. The battery becomes fully charged after power has been applied for 160 hours.

Hardware switches on the side of the circuit boards provide the means to configure most simple applications. These configuration switches are described in the following paragraphs. When power is applied to the unit, the front panel indicators flash for approximately 10 seconds as the unit executes a self -test function. If an ambiguous configuration has been programmed, the front panel indicators continue to flash after the self-test is completed. The configuration must then be reviewed to correct the error.

The unit is hardware configured using three DIP switches, a rotary switch, and two jumpers. All are located on the top edge of the circuit boards (refer to Figure 2-1 above). The front panel rotary switch selects BERT patterns and is described in the Operations chapter. The numbering system used for each switch position is as follows: Position 2 of Switch S4 is referred to as Switch S4 -2, and so on. Before installation, verify each configuration switch setting. A removable configuration guide is included in the rear of this manual to record option selections for reference.

Configuration Switch S4

Switch S4 is used to set the configuration parameters listed in the following paragraphs.

Network Coding

Position S4-2 sets the network line coding to AMI or B8ZS.

Down: AMI Up: B8ZS

Network LBO

Positions S4 -3 and S4-4 set the line build out signal level of the transmit data (TXD) from the unit to the network. The output level is factory set at 0 dB. It may be attenuated by -7.5 dB, -15 dB, or -22.5 dB if operating conditions require that it be changed. The telco should provide the proper setting to the user.If unsure of the exact setting, then leave it at the default value. The values are listed in the following table.

Bit Rates

Position S4-5 works in conjunction with rotary switch S7 to set bit rate

configurations. Refer to Rotary Switch S7 on page 2-7 for further information. The missing rates are N×56 and N×64, where N=15,17, 21, and 23. All 24 rate configurations can be programmed through software control by using the NMS or SUPV ports.

Clock Source

Positions S4 -6 and S4-7 determine the source of unit clocking. The most common timing source for most CSU /DSU applications is to derive timing from the network. The 3001 may also be optioned to time from an internal standard, from the T1 DTE, or from the high-speed data interface as shown in Table 2-2.

Channel Assignment

Position S4-8 selects the channel assignment mode for network T1 DS0s that carry data to the high-speed port. Contiguous assignment assigns the channels as a block beginning at channel one. For example, if the high-speed port data rate is to be 256 kbps (as defined by rotary switch S7 in on page 2-7), the unit would assign network channels 1 through 4 to the high-speed port.

Unit Configuration 2-5

If the Alternate channel mode is selected, channel assignments are made with an idle channel following each data channel. For the above example, data would be carried on channels 1, 3, 5, and 7 and channels 2, 4, 6, and 8 would be set idle (set to binary code 01111111). The advantage of alternate channel assignment is that T1 ones density requirements are maintained by the idle channels rather that placing any restrictions on the high-speed data.

Down: Contiguous Up: Alternate

Address Switch S5

Switch S5 is used to set the unit address. When using the EM8000 Element Manager, 8100A Site Controller, or other network manager controlled products with the 3001, each element in a group must have a unique unit address. Up to 250 units (with addresses from 1 to 250) can exist in a group. If the unit is not

connected to a network manager, the NMS unit address should be left at the factory default setting of 1.

Switch S5 has 8 positions used to create an 8 -bit binary code for an address in the range of 1 to 252. Switch position S5-1 is the least significant bit (LSB) and S5- 8 is the most significant bit (MSB). If a switch is down, its value is 0 and if it is up, its value is that of the upper location. The values are additive. For example, to set a unit address to five (5), position S5-3 (binary value = 4) and position S5-1 (binary value = 1) would be set Up for a unit address of 5 (4 + 1). All other positions would be set down.

Rate Multiplier

Position S6-7 is used to set the multiplier for the input timing. The unit can operate at any data rate that is a multiple of 56 or 64 kbps. Selecting N×64K provides port bit rates that are multiples of 64 kbps. The ones density requirements of the T1 network line must be ensured in this mode. Selecting N×56K allows port bit rates that are multiples of 56 kbps. The unit maintains ones density for the selected DS0 channel in this mode.

20 out of the 24 possible bit rate configurations are available through these hardware settings. The missing rates are N×56 and N×64, where N = 15, 17, 21, and 23. All 24 rate configurations can be programmed through software control by using the NMS or supervisory ports. The terminal interface program also allows the high-speed port to be mapped to a block of DS0s that begins at a user- selectable starting channel.

For units equipped with the T1 DTE port option, channel numbers beyond those assigned to the high-speed port are automatically mapped through to the T1 DTE. In the alternate channel mode, every data channel is followed by an idle channel assignment. Therefore, the even channels are quiet and are not available to the T1 DTE port.

Supervisory Port Connection 2-9

Supervisory

Port

Connection

The front panel supervisory port serves several functions. A modem may be connected to the SUPV port for remote access or use of the COA (call on alarm) feature. For cabling convenience, the

supervisory port may be used to connect the element manager into the 3001 network (refer to NMS Connection on page 2 -10).

The supervisory port bit rate is set by configuration Switch S6. The port is a serial RS-232 DCE port configured for 8 bits, no parity, and 1 stop bit. The physical connection is a 6-pin modular jack with the pinout shown in Table 2-8.

High-speed

Port

Connection

The high-speed port connection [on the rear panel of both the stand-alone (Figure 2-6) and the chassis unit (Figure 2-11)] utilizes a female subminiature DB-25 connector. If the unit is connected to an EIA-530 DTE-type device, a one-to-one DB-25 cable is all that is needed. If the unit is connected to an RS449-compatible interface, an adapter cable must be used to match the 37 -pin RS-449 standard. The V.35 option also requires an appropriate adapter cable to connect to devices that use the standard 34-pin V.35 interface. Pin functions for the high-speed port interface are listed in Table 2-9.

NMS

Connection

The PRISM 3001 is fully compatible with the TxPORT EM8000 Element Manager and 8100A Site Controller. The EM8000 and 8100A software systems are used to manage small to large networks of TxPORT network access products.

An element may be accessed by using an RS-232 connection from the serial port of the computer running the EM8000 program to the element’s SUPV port or the NMS IN and NMS OUT ports. The different connection methods are described in the following paragraphs.

SUPV The EM8000 workstation or the 8100A Site Controller may be directly connected to the 6-pin modular serial port connector labeled SUPV (also refer to Supervisory Port Connection on page 2-9). When a group of elements is connected in an NMS chain, the EM8000 or 8100A may be connected to the supervisory port of any one of the elements. This element can then route messages onto the NMS chain to reach the other elements. The call on alarm (COA) feature works through the SUPV port only.

NMS IN/ OUT

The two 6-pin modular connectors labeled NMS IN and NMS OUT on the rear panel may be used for connection to the EM8000 or 8100A. This port is

configured in this manner to allow the connection of multiple collocated units in a daisy chain IN /OUT bus arrangement as shown in Figure 2-7. The OUT port of one element is connected to the IN port of the next element, and so on, to form a complete chain among the group of elements.

NMS Connection 2-11

All units on the same NMS chain must use the same NMS bit rate.

NMS Split Cable

The EM8000 may be connected directly into the NMS chain between two elements if connection to the SUPV port is not desirable. A Y-cable is used from the EM8000 serial port which splits the transmit and receive signals into two 6-pin modular connectors for the NMS IN and NMS OUT ports. Ordering information for this cable is found in Table 1-2 on page 1-8.

NMS IN Only

The NMS IN connector provides both the transmit and receive signal pair. This port may be used for a modem connection or as a VT100 terminal interface (explained in the Terminal Operation chapter).

Chassis Operation

EM8000 and 8100A operation in the 12- slot chassis is similar to operation with the stand-alone unit with the exception that all elements are already chained together in the chassis. The front panel SUPV and the rear panel NMS ports operate in the same fashion.

The NMS address, port bit rate, and power up configuration mode can be set only by the configuration switches. The physical connection is a 6-pin modular

connector with the following pinout. This port is a serial RS-232 DCE port configured for 8 bits, no parity, and 1 stop bit.

T1 DTE Port

Connection

The 3001 provides an optional T1 DTE port interface for drop and insert applications. The DSX-output level should be set as instructed in T1 DTE LBO on page 2-8. The DTE physical interface for both the stand -alone unit and the chassis mounted unit is a standard RJ-48C 8- pin modular jack with the pinout shown in Table 2-11.

Network

Connection

The network side of the 3001 is referred to as the network interface. This interface contains an ALBO to allow the unit to be located a substantial distance away from the telco network interface (receive level to -27 dB).

The network interface line build out levels should be adjusted as instructed in Network LBO on page 2 -4. The maximum suggested cable lengths for unit connection to the network are listed below. Calculations are based on a cable temperature of 70°F, 0.083-µF/mile capacitance, a 27-dB loss, and a 100-Ω, non-loaded, twisted pair cable. PIC refers to plastic insulated cable.

The network physical interface for both the stand-alone unit and the chassis mounted unit is a standard RJ-48C 8- pin modular jack with the pinout shown in Table 2-13.

NET/External Clock Connection 2-13

An alternate method of connecting the network is through the Network /External Clock contacts provided on the rear of the unit. Refer to NET /External Clock Connection below.

Disconnection Notice:

In accordance with FCC Rules, Part 68.218(b), the telephone company must be notified before disconnecting the CSU/DSU.

NET/External

Clock

Connection

Contacts are provided on the rear of the stand-alone unit to permit connection to an external timing source (using pins 1 and 2). An alternate method for network connection is also provided with pins 3-6. Connection information is shown in Table 2-14.

The station clock input on the standard 3001 unit is designed to accept TTL or bipolar signal levels. The station clock is commonly available as a 64 kHz, bipolar RTZ signal referred to as a composite clock. The unit, however, also accepts any unframed all ones bipolar RTZ signal with a level of 1.5 to 4 volts peak and a frequency of 1.544 MHz or any multiple of 56 or 64 kHz. An RS422/423- compatible station clock input, with the same range of input frequencies, is also available as a special option.

Contacts are also provided on the rear of the 12-slot chassis unit to permit connection to an external timing source (using TB1, pins 1 and 2). The station timing is configured through the Terminal Interface. Refer to Line Parameters on page 4-15.

Alarm

Connection

The stand -alone unit and the chassis modular unit provide rear panel alarm relay contacts. These dry (isolated) alarm contacts permit connection to a remote indicating device.

Stand-alone Unit

The connection for the stand-alone unit is made on pins 5 and 6 of the Alarm/Power connector as shown in Table 2-15.

Pin 5 is configured to operate in either a normally open (NO) or normally closed (NC) mode as determined by the setting of the alarm relay jumper shown below. This jumper is located on the circuit board as shown in Figure 2-8.

NO and NC refer to the contact’s relationship to the common contact under a no

alarms condition. Move the jumper to NC for normally closed operation (opens on

alarm) or to NO for normally open operation (closes on alarm).

Make connections to the contacts using 20-gauge stranded wire (or similar). Contacts are rated at 0.3 amperes AC or 1.0 amperes DC.

Chassis Unit

Alarm conditions from all modules in the chassis are bused together in parallel and are presented on a single set of alarm relay contacts which permit connection to a remote indicating device. When connected, Pins 3 and 4 on terminal strip TB1 operate in a normally open mode. Refer to the 1051 -2 Chassis Configuration Guide for more information.

All PRISM 3001 modules in a common chassis must use the normally open contact mode.

Make connections to the alarm contacts using 20-gauge stranded wire (or similar). The contacts are rated at 120 mA AC or 120 mA DC.

Power

Connection

The stand -alone unit and the modular chassis unit require a -48 VDC power source that is capable of supplying 165 mA current. Power supplies are available from TxPORT and are listed in Table 1-2 on page 1-8.

Stand-alone Unit

The power source is connected to pins 1 and 3 of the Power and Alarm terminal as shown in Table 2-15.

Connect the ground lead before applying power to the unit.

Connect a chassis ground lead (18 - to 20 -gauge is recommended) to the Frame Ground terminal (pin 4). Connect the other end of this lead to an appropriate facility ground. Often, the 48 VDC return is also ground. In that case, both return and ground leads should be connected to ground.

D/I Option

(29)

Power Connection 2-15

Connect the -48 VDC lead to the -48 VDC terminal (18- to 20-gauge recommended). Connect the return lead to the 48 VDC return terminal. When power is applied to the unit, the front panel indicators flash for approximately 10 seconds as the unit executes a self-test function.

If an ambiguous configuration has been programmed, the front panel indicators continue to flash after the self -test is completed. If the unit is correctly configured, the green STATUS indicator on the front panel lights.

Chassis Unit

When operating the 3001 in the 12-slot chassis, all units are powered by -48 VDC sources which are connected to the 6-position terminal strip TB2 on the rear of the chassis. The chassis is designed with two power buses. The A bus feeds the odd slots (1, 3, 5, 7, 9, and 11). The B bus feeds the even slots (2, 4, 6, 8, 10, and 12). Connect a ground lead (18 - to 20-gauge) to the terminal marked Frame Ground on TB2, pin 2. Connect the other end of this lead to an appropriate facility ground.

Connect the ground lead before applying power to the unit.

Three modes of powering the chassis are available.

Redundant Power Source

The chassis is shipped with a redundant power board installed on power connector TB2. This board allows the connection of two independent -48 VDC supplies operated in a redundant mode. All slots in the chassis are powered from the combined input of the A and B power supplies. If either supply fails, the other powers the entire chassis.

To operate in the redundant power mode, connect the A bus -48 V IN (A) and + 48 V RTN (A) terminals on the redundant power board to the corresponding terminals of power supply A. Connect the B bus - 48 V IN (B) and + 48 V RTN (B)

terminals to the corresponding terminals of power supply B.

Single Power Source

When using a single power source, simply connect the A bus -48 V IN (A) and +48 V RTN (A) terminals on the redundant power board to the corresponding terminals of power supply A. This is essentially the same as the redundant configuration with power supply B not operational.

If not using the redundant power board, the A bus and the B bus must be connected together on the rear of the chassis with a jumper (pin 3 to pin 4 and pin 1 to pin 6).

Dual Power Source

When using a dual independent power supply, one - 48 VDC source feeds the A bus while another -48 VDC source feeds the B bus. First, remove the redundant power board. Connect the A bus 48 V Return and -48 VDC terminals to the corresponding terminals of power supply A (to power the odd-numbered slots). Connect the B bus 48 V Return and -48 VDC terminals to the corresponding terminals of power supply B (to power the even-numbered slots).

Each 3001 requires a 165-mA current. Ensure that the proper fuse size is used. Refer to the 1040 Power Shelf configuration guide.

Introduction

This chapter contains general operation instructions for the TxPORT PRISM 3001 front panel. The unit may be controlled manually using the front panel and the circuit board configuration switches (configuration switches are discussed in the Installation chapter).

The Terminal Operation chapter covers the firmware-controlled Terminal Interface program, which provides more control. The unit may also be controlled using the TxPORT EM8000 Element Manager (refer to the EM8000 reference manual) or 8100A Site Controller.

Front Panel

Controls and

Indicators

The front panel contains 19 LED indicators which convey status, alarm, and test information. The front panel also contains a test switch, a supervisory port connector, and a BERT pattern switch. The following descriptions are referenced to Figure 3-1.

General Status Indicators

1 STATUS: The unit has two LED indicators on the front panel bezel that are exposed whether the access door is open or closed. These general status LEDs provide a quick check of the unit’s operating condition (Go or No Go).

If neither LED is on, the unit is not powered. If the green LED is on, the unit is powered and functioning normally. If the red LED is on, there is a line fault that exceeds alarm thresholds or another type of unit failure. The problem can be isolated by further examination of the other front panel LEDs as described in the following paragraphs. NMS alarms are displayed by the two LEDs alternately turning red and green about every half second which occurs when the unit is managed by an 8100A that detects a duplicate address or invalid address (0 to 63 are valid). The 8100A detects these error conditions and notifies the unit to enter an NMS-alarm condition. Once the error condition has cleared, (either the

duplicate address is removed or an invalid address is corrected) the 8100A notifies the unit to clear the NMS-alarm condition.

2 TD: This green LED lights during a mark condition on the high-speed transmit data line.

3 RD: This green LED lights during a mark condition on the high-speed receive data line.

3-2 OPERATION

4 RTS: This green LED lights when the request to send signal is active.

5 DTR: This green LED lights when the data terminal ready signal is active.

6 Activity Indicators: These two small, recessed LEDs indicate supervisory and network manager port activity.

Alarm Controls and Indicators

7 ACO: This yellow LED lights whenever the alarm cut off switch is placed in the left on position. It indicates that the alarm relay contacts are disabled.

8 ACO SW: The alarm cut off switch controls the alarm relay circuitry. If the switch is placed in the left on position, this circuitry is deactivated.

9 BV /CR / FE: This LED lights one second for each second that has an occurrence of bipolar violations (BPV), cyclic redundancy check (CRC) errors, or frame bit errors (FBE).

10 LOS/OOF: This LED blinks with a loss of signal (LOS) from the network. It lights constantly when an out of frame (OOF) condition is detected.

11 AIS: This alarm indication signal LED lights if an unframed all ones condition is detected from the network.

12 REM ALM: This LED lights constantly when a remote (yellow) alarm signal is received.

13 LOC ALM: This LED lights when a local alarm exceeding alarm thresholds exists.

Refer to Alarm Parameters in Alarm Parameters on page 4 -17 for more information on alarm thresholds.

Test Controls and Indicators

14 LLB: This LED lights continuously when the network interface is in a line loopback. It flashes when the T1 DTE interface is in a line loopback. With PLB, this LED also lights continuously when the unit is in NET MLB or flashes when the unit is in DTE MLB.

loopback. With LLB, this LED also lights continuously when the unit is in NET MLB or flashes when the unit is in DTE MLB.

16 FLB: This LED is active for port loops. It lights continuously when the unit is in a fractional (high-speed port) loop.

17 TST: This LED lights continuously during a Far or a Local test. It flashes while loopback codes are transmitted at the start of a Far test and while unloop codes are transmitted at the end of a Far test.

18 ERR: This LED lights when BERT pattern errors are detected.

19 Test Switch: This switch (FAR /LOC) is used for local testing. Refer to Test Switch for more information.

20 Pattern Select: This switch determines the BERT pattern sent by the unit when the test switch (item 19) is in the FAR or LOC position. Refer to BERT Pattern Select on page 2 -4.

21 SUPV: The supervisory jack provides direct terminal access to control the unit and gather status/facility performance data. Refer to Supervisory Port on page 2 -4 for more information.

Front Panel

Testing

The previous section gave a brief description of each front panel control and LED indicator. This section explains the front panel test functions. Testing may also be performed using software control from the EM8000 Network Manager, 8100A Site Controller, or the terminal interface program (refer to the Terminal Operations chapter).

Test Switch

This switch (labeled FAR/LOC) is used for local testing. When in the FAR position, the unit sends five seconds of IBLC (in-band loop codes), then switches to the test pattern selected by the Pattern Select rotary switch. When transmitting IBLC, the test LED blinks. When transmitting a test pattern, it lights continuously. The ERR LED lights for one second when a bit error or sync loss on the returned data is detected.

When the test switch is returned to the normal center position, the unit sends five seconds of loop down code (100) and then returns to its normal operating mode. When the Test switch is set to Local, the unit performs a network LLB as shown in loopback diagram #2 (see Figure 4-7 on page 4-11). The LLB and TST LEDs light.

Test Access Jacks

Units with four bantam jacks provide access to the T1 line on the DTE side of the CSU. Two (MON) are used for non-intrusive network monitoring in both

directions. The other two (NET) allow inserting signals to and from the network using a T1 test set. This is shown in Figure 3-2.

(34)

3-4 OPERATION

BERT Pattern Select

This rotary switch determines the BERT pattern sent when the Test switch is in the FAR position. Table 3-1 shows the corresponding BERT test pattern sent when the rotary switch is set to positions 0 through 9. Additional patterns are available through the Terminal Interface program (refer to Bit Error Rate Testing (BERT) on page 4 -13).

When the switch is set to Flash (position 9) and the test switch is set to Local, the unit goes into the Flash download mode automatically. If the unit is placed in this mode accidentally, simply set the switch to another position and wait while the unit reboots.

Supervisory Port This 6 -pin modular RS-232 supervisory jack provides direct terminal access for controlling the unit and gathering status and performance data.

The supervisory port serves several functions. A terminal may be connected to this port for external software control. A modem may be connected for remote access. The port supports the call on alarm feature. The EM8000 Element Manager or 8100A Site Controller may be also connected through this port. Refer to Supervisory Port Connection on page 2-9 for connection information.

Introduction

This chapter describes the screens and menus associated with the TxPORT PRISM 3001 terminal interface, which is a firmware application program embedded inside the unit.

The terminal is connected to a 6 -pin modular jack on the PRISM 3001. Refer to the Installation chapter for more information on user connections. Cables are available for most typical connections. Standard cables and ordering numbers are listed in Table 1-2 on page 1-8. Contact TxPORT for any assistance in cable selection.

In addition to the 54016 and T1.403 protocols, proprietary messages can be sent over the facility data link (FDL) from the near-end PRISM 3001 to the far-end PRISM 3001. A local RS-232 terminal connected to the unit may access a far-end PRISM 3001. Thus, the remote unit may be queried for status and statistics, configured, or looped for testing as if the terminal is connected to it directly.

System

Description

The terminal interface requires an ANSI-compatible VT100 terminal (ASCII), or a computer running an ANSI terminal emulation program. The terminal interface uses ASCII break and escape functions, which are implemented differently with various terminal emulation programs. The software supplied with the emulation program should be consulted for further reference.

The 3001 unit has two serial interface RS-232 ports. Either of these ports may be used for the terminal interface program or as a connection to the EM8000 Element Manager or an 8100A Site Controller. One port is a pair of daisychain-type rear panel connectors labeled NMS IN and NMS OUT. The other port is located on the front panel and labeled SUPV. Serial bit rates of 1200, 2400, 9600, or 19200 bps may be selected using option switch S6 (refer to the SUPV and NMS port bit rates, Configuration Switch S6 on page 2-5).

Both serial ports support the same custom protocols that allow the terminal interface, EM8000, or 8100A to request and receive performance and configuration data from the unit. The unit automatically determines which protocol is needed.

Modem Compatibility

The PRISM 3001 terminal interface supports the use of an AT-command-set- compatible modem on either, or both, of the NMS IN and SUPV serial ports. The modem should be optioned to ignore DTR, enable auto answer, inhibit command echo, and return verbose result codes.
