Introduction

SURPASS hiT 7060 is a multi-service provisioning platform with add/drop, terminal and Cross-Connection (CC) functionality for universal installation at all network levels.

All applications can be implemented using one main shelf with four extension shelves. Reconfiguration during operation is possible.

SURPASS hiT 7060 transports data signals and standard voice based traffic over one single platform. For transporting data in the most economic way, the SURPASS hiT 70xx product line combines technologies such as GFP, LCAS and Resilient Packet Ring (RPR) with the reliability and robustness of SDH networks and a Quality of Service (QoS).

SURPASS hiT 7060 provides full cross-connectivity between all interfaces. The capacity of the switching fabric is up to 160 x 160 VC-4 + 4032 x 4032 VC-12 equivalents. This applies to the VC-4, VC-3 and VC-12 layer and to all CC types (unidirectional, bidirectional and broadcast).

SURPASS hiT 7060 can be used as:

• Terminal Multiplexer (TMX)

• Add/Drop Multiplexer (ADM)

• Local Cross-Connector (LXC)

in multi-service transport and aggregation/switching network applications. State-of-the-art protection switching mechanism is supported to enable an optimum network with very highest reliability possible - depending on the relevant network topology and the requirements of the network operator (see Chapter 5.10).

One single SURPASS hiT 7060 main shelf supports up to four SURPASS hiT 7035 Extension Shelves which make it possible to support 1197 × 2 Mbps interfaces simultaneously add/drop in one platform.

Network Applications

For SDH general logic applications, the NEs can be used in a straightforward way of creating point-to-point connections, linear chain configurations and ring configurations.

• Terminal-to-terminal topologies (see Chapter 4.1)

• Linear topologies with add/drop function (chains) (see Chapter 4.2)

• Ring network functionality (see Chapter 4.3)

For SDH special applications to provide powerful services, the NEs can be used in a way of transporting data service.

• Data service applications (see Chapter 4.4)

4.1 Terminal-to-Terminal

Topologies

Terminal-to-terminal links are supported by SURPASS hiT 7060 NEs in TMX application with the option of 1 + 1 MSP for STM-16/4/1 interfaces.

Fig. 4.1 shows a straightforward point to point network with one TMX at the transmitting end and another at the receiving end. It is using MSP protection switching.

4.4 Data Service Applications

SURPASS hiT 7060 provides data transport over SDH and offers various data applications in addition to the traditional Time Division Multiplex (TDM)

applications.

The SURPASS hiT 7060 system supports the following data transmission services:

• Ethernet Private Line (EPL)

• Ethernet Virtual Private Line (EVPL)

• Ethernet Private LAN (EPLan)

(26)

4.4.1 Ethernet Private Line

SURPASS hiT 7060 EPL service offers dedicated, point-to-point Ethernet connectivity at FE rates (10 Mbps or 100 Mbps) and GE rates (1000 Mbps). The EPL can be used to support applications such as LAN-to-LAN

connectivity, storage area networking, Internet access or disaster recovery solutions. hiT 7060 hiT 7060 hiT 7060 hiT 7060 VC-4-xV or VC-3-xV VC-12-xV or VC-3-xV FE 8 × FE/T 8 × WAN Ports

4.4.2 Ethernet Virtual Private Line

For the EVPL, the customer still gets point-to-point connectivity, but over shared instead of dedicated bandwidth. Each node has the Layer 2 (L2)

(27)

switching capabilities to provide statistics multiplexing, per VLAN control and Spanning Tree Protocol (STP) function and Ethernet based rate limiting per VLAN or port.

The EVPL is useful when creating hub-and-spoke architectures in which multiple remote offices all require access to a headquarter or multiple customers all require access to an Internet Service Provider’s (ISP) Point Of Presence (POP). hiT 7060 hiT 7060 hiT 7060 hiT 7060 VC-4-Xv FE 6 × FE/L2 VC-12-Xv 6 × FE (Client) 2 × WAN ports GE FE 2 × GE + 8 × FE/AE VC-4-Xv or VC-12-Xv 2 × GE + 8 × FE (Client) 32 × WAN ports VC-12-Xv Headquarter Remote

Fig. 4.7 Ethernet Virtual Private Line

4.4.3 Ethernet Private LAN

The EPLan service provides multipoint connectivity over dedicated bandwidth, i.e., it may connect two or more subscribers (customers). Subscriber data sent

(28)

from one customer can be received at one or more of the other customers. Each site (customer) is connected to a multipoint-to-multipoint Ethernet Virtual Concatenation (EVC) and uses dedicated resources so different customers’ Ethernet frames are not multiplexed together. As new sites (customers) are added, they are connected to the same multipoint EVC, thus simplifying provisioning and service activation. From a subscriber standpoint, an EPLan makes the MSTP network look like a LAN.

The EPlan architecture differs from EPL in that rather than use a predefined mapping between VLAN tags and link connections, the operator’s network equipment, uses Ethernet switching (i.e. Bridge learning) to pass Ethernet frames to the appropriate link. However this makes it difficult to guarantee performance as network Ethernet switching introduces additional latency and probability of increased packet loss.

SURPASS hiT 7060 brings multiple Wide Area Networks (WAN) interfaces into L2 switching. Customer service can be delivered through dedicated Virtual Concatenation Groups (VCG) with little latency and little packet loss. The WAN interface can be provisioned individually on TNMS-M.

Fig. 4.8 Ethernet Private LAN

4.4.4 Ethernet Virtual Private LAN

The EVPLan has gone by many names over the past two years, from Virtual Private LAN Service (VPLS) to Transparent LAN Service (TLS), to Virtual Private Switched Network (VPSN). Regardless of how it is termed, the EVPLan is a network service providing L2 multipoint connectivity between Ethernet edge devices. Customer separation is accomplished via the encapsulation or Ethernet virtual connections.

The EVPLan is designed as the most cost-effective service for the carrier, as it can leverage shared transmission bandwidth in the network. Because it is a multipoint service, it can be complex to administer. Customer service

separation by provider VLAN tags is not likely to be sufficient because of the limited address space of the provider VLANs’ IDs (only 4096) and hence other

(30)

service delivery technologies providing customer frame encapsulation must be used such as Multi-Protocol Label Switching (MPLS), MAC-in-MAC and RPR. By merging RPR technology with Virtual Container (VC), GFP and MSTP, SURPASS hiT 7060 can add statistical multiplexing and traffic engineering to the VC-enabled MSTP equipment. The 2 × GE + 8 × FE RPRE card will encapsulate the RPR frames into the GFP frames. The GFP frames are then mapped into a virtual concatenation group VC-4-Xv (X= 1 to 8) which connects the consecutive WANs of these VC-4-Xvs in the MS-SPRing. The RPR will be provisioning over SDH.

In RPR, three classes of services (high, medium and low) defined by IEEE 802.17 are transmitted over the ring architecture.

RPR has the following features:

• Auto-negotiation

• Flow control

• Rate limiting

• Spatial reuse

• Source weighted fairness

5.2.2 Switch Fabric Functions

The switching device provides the HO and LO switching at the same time.

Capacity of the CC Fabric

SURPASS hiT 7060 has the following CC capacity:

• High Order Cross-Connection (HOCC): 25 Gbps (160 × 160 VC-4s)

• Low Order Cross-Connection (LOCC): 10 Gbps (4032 × 4032 VC-12s)

Cross-Connection

All types of cross-connections are possible. The switch fabric is a non-blocking square structured fabric for point-to-point and point-to-multipoint connections.

Granularity

The configurable and simultaneously usable switching hierarchies of the fabric are VC-4, VC-3 and VC-12.

HO and LO VC-n Connectivity

The switching fabric allows the following connections:

• Unidirectional connections

• Unidirectional point-to-multipoint (including 1 + 1 SNCP head end)

(36)

• Broadcasting (HOCC 1 : 4, LOCC 1 : 63)

• Drop and continue (broadcast 1 to 2 + SNCP tail end)

• Selector 2 to 1 (protected tail end for 1 + 1 SNCP)

Concatenation

Virtual concatenated VC-12, VC-3 and VC-4 signals are supported. Protection switching for virtual concatenated signals VC-4, VC-3 and VC-12 is also supported. The group of constituent paths that belong to a concatenated signal is determined by the Telecommunication Network Management (TNM) and written to an internal configuration table. Using this information, the

SURPASS hiT 7060 software is able to set signal fail or signal degrade alarms for all paths of a concatenated signal channel. In order to keep the (differential) delay of the signals low, all constituent paths of a concatenated signal must be on the same optical trail. It results in a bundling rule for the TNM.

5.2.3 Multiplex and Mapping Functions

SURPASS hiT 7060 transmits SDH and PDH signals.

Fig. 5.3 shows the organization and relationship of SDH and PDH multiplex structures.

Chapter 9.1 summarizes the possible user data interfaces for the SURPASS hiT 7060 NEs.

Fig. 5.3 SDH/PDH Multiplex Structures

5.2.3.1 SDH HO/LO Multiplexer and Mapping Functions

SURPASS hiT 7060 implements the following HO/LO multiplexing and mapping methods:

• VC-4 containers are aligned (with frame offset information) with an AU-4, according to ITU-T G.707. The AU-4 may further be mapped via AUG-1 into STM-1, or further via AUG-4 into STM-4. STM-16 follows the same pattern.

• VC-3 containers are aligned (with frame offset information) with a TU-3, according to ITU-T G.707. The TU-3 is further mapped via TUG-3 into VC-4.

• VC-12 containers are aligned (with frame offset information) with a TU-12, according to ITU-T G.707. The TU-12 is further mapped via TUG-2 and TUG-3 into VC-4.

5.2.3.2 PDH Mapping into SDH Containers

SURPASS hiT 7060 implements the following mapping of PDH signals on SDH containers:

(38)

• 2 Mbps signals are mapped into a VC-12 asynchronously, according to ITU-T G.707. The VC-12 is further mapped on a VC-4, via TU-12, TUG-2 and TUG-3.

• 34 Mbps and 45 Mbps signals are mapped into a VC-3 asynchronously, according to ITU-T G.707. The VC-3 is further mapped on a VC-4, via TU-3 and TUG-3.

5.2.3.3 Ethernet Packet Multiplexer and Mapping Functions

SURPASS hiT 7060 supports Ethernet frame mapping into SDH containers. So LAN traffic can be transported over different SDH payload sizes (requires encapsulation by using an appropriate protocol and mapping of the resulting frame into an SDH container).

For encapsulation, the GFP (GFP-F according to ITU-T G.7041) is used. The encapsulated protocol frames can be mapped into different SDH containers using the virtual concatenation technique.

Ethernet Mapping into SDH Containers

SURPASS hiT 7060 supports a flexible mapping scheme:

• Ethernet Mapping into HO virtually concatenated containers

Encapsulated GFP-F frames can be mapped into different HO container sizes providing a scalable solution that can cover network applications with very different transport capacity requirements.

Mapping into VC-4, VC-4-Xv (x = 1 to 7)

The GE interface cards support this mapping function.

• Ethernet Mapping into LO virtually concatenated containers

Encapsulated GFP-F frames can be mapped into different LO container sizes providing a scalable solution that can cover network applications with very different transport capacity requirements.

Mapping into:

− VC3, VC-3-Xv (x=1 to 3 for FE or x=1 to 21 for GE)

− VC12, VC-12-Xv (x = 1 to 46)

The virtual concatenation for VC-3 supports both FE and GE.

GFP-F Mapping

GFP is supported by the FE interfaces.

GFP provides a generic mechanism to adapt traffic from higher-layer client signals over an octet synchronous transport network. This is a simple and robust encapsulation method for packet traffic. All of the relevant MAC layer information, from destination address through Frame Check Sequence (FCS) inclusive, is preserved intact by the mapping.

(39)

SURPASS hiT 7060 uses a Protocol Data Unit (PDU) oriented, frame-mapped adaptation mode (GFP-F) for the client signal adaptation.

GFP-F does not rely on flag characters, and associated control escape octet, for frame delineation purposes as High level Data Link Control (HDLC) does. Instead, GFP-F uses a variation of the Header Error Control (HEC) based frame delineation mechanism defined for Asynchronous Transfer Mode (ATM). This avoids non-deterministic expansion of the client signal due to insertion of control escape characters.

5.3 Ethernet Transparent or Layer 2 Functions

SURPASS hiT 7060 supports Ethernet data transparent transmission and L2 functions as follows:

Transparent LAN

SURPASS hiT 7060 supports Ethernet transparent service which means the Ethernet frame is encapsulated to the SDH containers and transmitted directly without L2 switching.

MAC address forwarding

SURPASS hiT 7060 supports up to 8 K MAC addresses on each Ethernet card, in which 2 K MAC addresses can be configured manually. Both multicast address and broadcast address are supported.

Access Control List (ACL)

The system can generate an ACL table based on the MAC address. The MAC entries listed in the ACL table are forwarded or discarded in different modes.

VLAN

SURPASS hiT 7060 supports VLAN functions including VLAN

tagging/detagging, filtering and forwarding, GVRP and up to 1022 VLAN IDs.

Flow control and rate limit

SURPASS hiT 7060 supports Ethernet flow control and input rate limit function to avoid traffic congestion.

• For the 6 × FE/L2 card, the LAN port rate limit ranges are from 200 Kbps to 100 Mbps in the step of 1 Kbps.

• For 2 × GE + 8 × FE/AE card, the LAN port rate limit ranges are from 64 Kbps to 100 Mbps for FE interfaces and from 64 Kbps to 1000 Mbps for GE interfaces in the step of 64 Kbps.

Link aggregation

SURPASS hiT 7060 supports link aggregation function on FE ports for LAN or WAN side.

(40)

Jumbo frame

SURPASS hiT 7060 supports up to 9.6 K bytes long MAC frame which

substantially facilitates the transmission of bandwidth-demanding service such as video and broadband access.

5.4 Clock Pulse Supply, Synchronization

Every NE clock may be synchronized by a very accurate timing source, normally by a Primary Reference Clock (PRC) according to the master-slave principle. The Synchronous Equipment Timing Source (SETS) is responsible for generation of system and output clock signals.

According to the ETSI recommendation, T3 and T1 are the synchronization timing sources, T0 is the internal NE system clock and T4 is the timing output interface. Selection SETS T4 T0 T2 T1 T3

Fig. 5.4 Timing Source Selection

5.4.1 Available Timing Sources

The SETS synchronization for SURPASS hiT 7060 is derivable from any of the following external ports:

• From any STM-1/4/16 ports (T1)

• From any one of 2 Mbps interfaces in E1 card (T2)

• From any external station clock input ports (T3).

(41)

A SURPASS hiT 7060 NE can run in free running, holdover, or locked mode. The normal synchronous mode is locked mode. If all of the reference sources fail, the system will switch to the holdover mode. The accuracy of the local oscillator is ±12 ppm.

A Synchronization Status Message (SSM) signal can be used to transfer the signal quality level throughout a network. This will guarantee that all NEs will always be synchronized to the highest quality clock available.

SURPASS hiT 7060 supports SDH SSM algorithm on all STM-N interfaces and on the framed 2 Mbps synchronization output signal (connected to the station output clock):

• SSM function support can be user provisioned as “enabled or disabled”. When the SSM function is disabled in the NE, all STM-N interfaces and the framed 2 Mbps synchronization output signal interfaces will send out a DNU (do not use for sync) signal.

• There are 4 possible quality levels specified in the SSM for timing reference sources: PRC, SSU-A, SSU-B, and SEC. In addition, DNU is specified in SSM. The quality of each timing reference source can either be retrieved from the incoming the SSM or provisioned from the network management system.

• SURPASS hiT 7060 supports the synchronization source switching algorithm based on SSM defined in ITU-T G.781.

• The wait-to-restore (WTR) time for the timing reference source is between 0-12 minutes and can be set from the network management system in minute increments. The default value is 5 minutes.

5.4.2 T0 System Clock

The T0 system clocks are used in the NE for traffic processing, OH/DCC busses, internal system communication between the SC card and each card, and for the distribution of the absolute time.

T0 clocks to each LC and MC slot include the following three signals:

• Clock signal 77 MHz; point to point distribution.

• Frame clock signal 2 kHz; point to point distribution.

• Absolute time signal 1 Hz; point to point distribution. T0 clocks to each TC slot include the following three signals:

• Clock signal 19 MHz; point to point distribution.

• Frame clock signal 2 kHz; point to point distribution.

• Absolute time signal 1 Hz; point to point distribution. All cards receive the T0 clocks.

(42)

5.4.3 Timing Output Interface

The System Management Interface Panel provides the following interfaces to offer synchronization to external devices:

• 2 Mbps, framed and unframed

• 2 MHz

5.4.4 Real

Time

Clock

For time stamps (time and date) in the SURPASS hiT 7060 error and operational messages, a real time clock is available (within the SETS). The date and time for the real-time clock within the NE can be set and requested from LCT/OS.

5.5 Retiming

In the retiming mode, the transmitter eliminates wander and jitter in the incoming clock.

While the rate of the outgoing 2 Mbps signal is normally equal to the rate of the 2 Mbps signal going into the SDH network, occasionally this relationship disappears.

A retiming function is necessary for suppression of jitter and wander which the 2 Mbps signal suffers during transmission in SDH and which makes the signal useless for carrying the synchronous frequency to the PDH domain.

To retime an outgoing 2 Mbps signal, means simply to retime this signal with the internal clock of the multiplexer equipment in which the desynchronization takes place. This can be done by reading the recovered 2 Mbps signal into an elastic store and timing the output of the elastic store with the system clock. When the device is set in the retiming mode all jitter and wander due to the multiplexing or demultiplexing process in the transmission is eliminated.

5.6 Laser Safety Shut-down

To prevent personal injury form emerging laser light in the case of the fiber break, SURPASS hiT 7035 supports Automatic Laser Shutdown (ALS) function according to ITU-T G.958 and ITU-T G.644. In the case of the signal failure at the optical receiver of SURPASS hiT 7035, the laser transmitter will

(43)

be switched off automatically. After the receiver receives a valid signal again, the laser transmitter is then switched on automatically.

ii

Note

ALS for GE ports in 2 × GE/T card is not supported.

5.7 External Alarm Interfaces

Failures signalled by any cards are processed by the main controller of the device, which forwards the detected alarm information to the alarm interfaces. The alarm interfaces are accessible via an alarm connector.

The SURPASS hiT 7060 alarm interfaces provide two outputs:

• Major urgent alarm (triggered by any Critical or Major alarms)

• Minor non-urgent alarm (triggered by any Minor alarms)

5.8 Engineering Order Wire

The SURPASS hiT 7060 system provides one RJ 45 connector for two EOW output channels (E1, E2) and/or F1 user channel. The EOW interface (ITU-T recommendation G.703 compliant) is located on the SC module front panel. Users may totally select all the channels of E1/E2 from the system, and will be terminated by the system. When E1, E2 and F1 bytes are not used, there will be only code “1” transmitted in these channels and the received will be ignored.

SURPASS hiT 70 XOW is an external box which connects the EOW interfaces via RJ-45 cable. The XOW provides telephone links to connect one or more NEs by using the Regenerator Section OverHead (RSOH) byte E1 and/or the Multiplex Section OverHead (MSOH) byte E2 for EOW communication. In addition, on the external XOW panel there is one V.11 interface for F1 channel, the physical interface DB15, accessing besides one RJ-11 interface for phone set connection.

With an external box SURPASS hiT 70 XOW connected with the EOW interface through a RJ 45 connector, the one to one call or multiple parts conference call can be performed among the nodes in the network.

(44)

ii

Note

Traditional EOW over E1/E2/F1 is available for SURPASS hiT 7060. This solution is based on management mode. In this mode SURPASS hiT 70 XOW can be managed via LCT or TNMS-M. Operators can assign or manage the telephone numbers in the box through the LCT or Telecommunication Network Management System (TNMS). At the same time the TNMS can obtain the state and events from the box.

SURPASS hiT 7060 uses VoIP technology to provide EOW function over DCC. When the Data Communication Network (DCN) tunnel function is enabled, VoIP is not recommended to be used.

5.9 Software/Firmware

The SC card is equipped with micro controllers for monitoring, controlling, and maintaining status information. They are programmed with embedded

firmware held in Flash-EPROMs.

A Compact Flash (CF) card is provided which can be installed in the SC card. All the software load of the NE is embedded in the CF card at the beginning. System gets the software from CF card while booting the NE for the first time. A new CF card with upgraded software will be provided during the system upgrade.

A software download facility is available. The download can be done remotely or locally via the element manager or LCT.

The internal configuration database of the system can be uploaded and downloaded. It is stored redundantly and robust to any card failure.

Besides the configuration database, there are two embedded software images in the SC card. One is used by the active software and the other is for backup. During the system upgrade, new software will be downloaded and stored into the backup image memory bank.

It will then be activated and the active image will be set as the new backup. Two software image designs can efficiently protect the system from system errors caused by wrong operation.

5.10 Protection

Architecture

SURPASS hiT 7060 provides powerful network and equipment protection functions.

(45)

5.10.1 Traffic

Protection

SURPASS hiT 7060 supports the following traffic protection functions:

• SNCP

• MSP

• 2-fiber MS-SPRing

• DNI

ii

Note

Traffic protection functions are partly coupled with equipment protection features. This is generally achieved by including some hardware components (e.g. SFP modules) within a protected signal section.

Each of the protection function is described as follows:

SNCP

SURPASS hiT 7060 supports both unidirectional and bidirectional SNCP protection on STM cards at VC-12, VC-3, VC-4, VC-4-4c and VC-4-16c levels. SNCP protection includes both inherently monitored SNCP/I and

non-intrusively monitored SNCP/N. The protection switching time for SNCP is less than 50 ms.

MSP

SURPASS hiT 7060 supports 1 + 1 MSP function on STM-1, STM-1E, STM-4 and STM-16 interfaces.

In 1 + 1 MSP, one dedicated channel is reserved to protect only one working channel. The client traffic is always transmitted over the working and

protection path simultaneously. In the case of the fiber break, the incoming traffic from the protection path will be selected automatically. All STM optical ports support both unidirectional and bidirectional 1 + 1 MSP functions in revertive and non-revertive modes.

2-fiber MS-SPRing

2-fiber MS-SPRing is a bidirectional ring in which both directions of traffic transmission use the same set of nodes under normal conditions. In the case of the failure on the working path, the traffic will be switched to the protection path. SURPASS hiT 7060 supports MS-SPRing at STM-16/4 level. The protection (detection and switching) is guaranteed to be finished within 50 ms. The WTR time is user configurable with a default value of 5 minutes.

DNI

(46)

5.10.2 Equipment

Protection

SURPASS hiT 7060 provides the equipment protections as follows:

1 : N protection for electrical 2 Mbps interfaces

SURPASS hiT 7060 supports an optional 1 : N (N=1 to 2) protection for the 2 Mbps PDH interface cards.

The automatic protection switching related information coming from the 63 x E1 working card (or protection card) is sent to the SC unit. When an E1 1 : N protection related defect is reported on the 63 x E1 working card (or protection card) and correlated by software as a valid Protection Switch Request (PSR), the SC module initiates a switch to the protection card (or the working card). As a result, the customer traffic will be forwarded through the protection bus to the protection card. The switch matrix will then select the traffic from the protection card.

1 + 1 protection for electrical 34/45 Mbps and STM-1E interfaces

SURPASS hiT 7060 supports an optional 1 + 1 protection for the 34/45 Mbps PDH interfaces and STM-1 electrical interfaces.

The automatic protection switching related information coming from the 3 × E3/DS3 or 4 x STM-1E working card (or protection card) is sent to the SC unit. When an E3/DS3 or STM-1E 1 + 1 protection related defect is reported on working card (or protection card) and correlated by software as a valid PSR, the SC module initiates a switch to the protection card (or the working card). As a result, the customer traffic will be forwarded through the protection bus to the protection card. The switch matrix will then select the traffic from the protection card.

Switch fabric, clock unit and power unit protection

In SURPASS hiT 7060 the SETS is integrated as a module inside the switch fabric card. Every NE can always be equipped with working and protection fabric/clock cards.

All the transmission functions and information within the working switching fabric will be duplicated and stored within the protection switching fabric, so that in case of failure, the protection switching fabric will take over the task of the defect switching fabric without any major delay.

From the SETS point of view, the working card will be configured as a master and synchronized to a reference source, while the protection card will be operating as a slave and synchronized to the working card.

In the event of failure of the working card, the protected card will take over the synchronization function from the defect card.

SURPASS hiT 7060 provides 1 + 1 power unit protection. In the event of failure of working power card, the protection power card will take over the power function from the defect card.

(47)

5.11 Operating Terminal TNMS-M SURPASS hiT 7060

LCT

NEs can be operated and monitored via the software TNMS-M SURPASS hiT 7060 LCT software.

The TNMS-M SURPASS hiT 7060 LCT is used primarily for local management and commissioning of NEs. The LCT is connected via the management

interface and allows the access to NE locally or remotely.

For further information about operation, control and monitoring via TNMS-M SURPASS hiT 7060 LCT, please refer to the TNMS-M SURPASS hiT 7060 LCT User Manual.

5.12 Connection to Network Management Systems

5.12.1 SURPASS NE connect to TNMS

Fig. 5.5 shows the integration of the SURPASS hiT 7060 NEs in the TMN system. Access from the TMN to SURPASS hiT 7060 NEs is fulfilled via Simple Network Management Protocol (SNMP) over TCP/IP/PPP (direct access) or TCP/IP/HDLC or TCP/IP/OSILight (via dedicated SOH channels within traffic links - DCCM or DCCR) interfaces.

OSILight is an Internet Protocol (IP) over ConnectionLess Network Service (CLNS) tunnel protocol stack. OSILight lets IP traffic be transported over CLNS, for instance, on the DCC of Open System Interconnection (OSI) based SDH equipment. OSILight enhances interactions with the CLNS network, allowing IP packets to be tunneled through the ConnectionLess Network Protocol (CLNP) to preserve TCP/IP services. The selection of Point to Point Protocol (PPP), HDLC, or OSILight is user configurable.

5.12.2 SMA NE connect to TNMS

Shown in Fig. 5.6, the remote SMA devices (other Nokia Siemens Networks products such as SURPASS hiT 7070, SURPASS hiT 7300, etc) are

connected transparently to the management system using Link Access Protocol on D Channel (LAPD) tunnel over Generic Routing Encapsulation (GRE).

GRE is a mechanism for encapsulating any network layer protocol over any other network layer protocol. In the general case, a network layer packet, called the payload packet, is encapsulated in a GRE packet, which may also include source route information. The resulting GRE packet is then

encapsulated in some other network layer protocol, called the delivery protocol, and then forwarded. The CLNP/GRE uses the CLNP PDU and End System to Intermediate System Routing Exchange protocol (ES-IS) packet as payload and IPv4 as delivery protocol.

The GRE module is triggered with callback functions form the OSILight stack or the VxWorks networking system. The OSILight stack provided interface functions to register and unregister GRE tunnel endpoints.

5.12.3 Third-party DCC transparency

SURPASS hiT 7060 also supports DCC transparency function in physical layer while the NE from other suppliers (third party) are connected to the TNMS system.

Using D1-D3 or D4-D12 channels, SURPASS hiT 7060 can let the

management information transparently pass through the third party NEs (see Fig. 5.7).

Note

1. While the 4 × STM-4 card is equipped in LC1, LC2, LC5 or LC6 slot, only the first port is supported, and this card would be seemed as 1 × STM-4. 2. The 4 × STM-1EW card has the same functions as the 4 × STM-1E card

except the E1/E2 and F1 overhead supported. Both of these two function cards can only interwork with the same type to provision 1 + 1 hardware protection.

3. The 2 × GE + 8 × FE/AE and 2 × GE + 8 × FE RPRE cards have the same functions as the old data service cards (2 × GE+ 8 × FE/A, 2 × GE + 8 × FE RPR). The only distinguishing feature is that the enhanced cards, which include the capital letter “E” in the name, can be reused in SURPASS hiT 7060 release 4.x subracks.

4. The 63 × E1/R (W/P) and 63 × E1/EC cards are long cards. The slot arrangement is shown in Fig. 6.5.

6.3 Power Supply Card: PWR

The power supply card supports -48 V (range -40 V ~ -72 V) Direct Current (DC) power. It converts the input supply voltage into regulated operating secondary voltages. The outputs are isolated from the input. All output circuits have a common reference point, which is connected to the grounding layers on the backplane.

A switch on the module allows user to turn on and off the power supply. There is one green color Light Emitting Diode (LED) labeled PWR on the module. The “on” status of an LED indicates that the corresponding power supply is on; otherwise the power supply is off.

The power supply card is a pluggable module and is hot swappable. SURPASS hiT 7060 supports dual -48 V DC power supply. There are two power supply slots located on the bottom row slot PWR1 and slot PWR2. One power supply card can be equipped in any one of the power supply slots to support the whole system, but the redundant power supply card offers 1 + 1 protection for system safety.
