The following figure shows the process for configuring BRI loops.
Figure 57 Loops table
The following table describes the fields found on the Loop main panel.
Table 38 Loops panel parameter values
Attribute Value Description
Loop <X01-X04> Each BRI module supports four loops (eight lines for T- loop programming).
Type T
S
This setting defines whether the loop supports trunks (T-loop) or device connections (S-loop). This variable can be different for different market profiles.
T-loop general settings
The Settings tab allows you to define loop characteristics. All of these settings are not required in all BRI markets. The following figure illustrates the Settings tab.
Figure 58 Settings subpanel—T loops
The following table describes the fields on this panel.
Protocol Euro
QSIG NI-2
Select the appropriate ISDN protocol.
The values displayed depend on both the market profile and software keycodes.
Euro - ETSI ISDN standard
QSIG - also an ETSI standard. Only appears if the ETSI
QSIG keycode is loaded. NI-2
Sampling (S loops only) Adaptive Fixed N/A
Select a sampling rate for the S-loop.
Fixed: two or more S-interface devices use the loop, and the length of the loop is less than 200 m (650 ft.). Adaptive:two or more S-interface devices use the loop, and the length of the loop is greater than 200 m (650 ft.). If one device is using the loop, the length of the loop can be a maximum of 1 000 m (3 230 ft).
ONN blocking Suppression bit Service code
Set the Outgoing Name and Number (ONN) Blocking. When you activate ONN, a user can press FEATURE 819 to block the outgoing name and number on a per call basis.
Programming note: Ensure that all telephones that have this feature available are assigned valid OLI numbers. Refer to “Programming outgoing number display (OLI)” on page 213.
Table 38 Loops panel parameter values
T-loop SPIDS and network DNs
These settings are only available for systems running a North American profile. The SPID numbers are supplied by the ISDN service provider. The following figure illustrates the SPIDs tab.
Table 39 Loops subpanel—T loops parameter values
Attribute Value Description
Clock source Primary External Secondary External Internal
Default: Internal
Primary External - uses clock from PSTN
Secondary External - used if system has more than one Loop
Internal - uses clock on BCM Protocol Type S-T user, T-T user
Default: S-T user
When set to S-T user, the BRI connection to the public network is treated like a line which appears on a set and is the termination end point for the call (Key system model).
When set to T-T user, the BRI connection to the public network is treated like a trunk, which allows tandems to other switches without first answering the call (PBX model).
Overlap: receiving <check box> Supports target lines in markets which use Overlap receiving signaling on the BRI trunks. Overlap receiving must be configured for each BRI loop. Overlap: length <0-15> Set the local number length for loops to interfaces that
receive overlap rather than enbloc digits. This number is the total length of the called party number received. This number is used to calculate the number of leading digits that need to be removed by the system.
Attention: This parameter appears only when Overlap receiving is enabled.
Example:
Public received number = 4502303 Target line received numbers = 303 Local number length = 7
Public received number length = 3
Thus the first four digits are deleted by the system. Send Name Display
(ETSI QSIG only)
<check box> If the switch allows outgoing name display, select the check box.
Figure 59 SPIDs and network DNs (T-loops, North America only)
The following table defines the fields on the SPIDs tab and indicates the lines.
Table 40 SPIDs and network DNs parameter values
Attribute Value Description
SPID Digits <digits> Supplied by your service provider. System running with North American country profiles support additional BRI services offered by ISDN service providers and defined by network SPID. The SPID allows you to enter a network connection that provides a path for voice or data services.
Number of B-channels 1, 2 North American BRI loops can support two B-channels. The SPID can be the same or different for the
channels.
Actions
Add (SPID digits) 1. Select the appropriate SPID (1 or 2). 2. Click Add.
3. Enter the SPID digits supplied by your ISDN service provider. 4. Click OK.
5. On the table, click the Number of B-channels field beside the number you entered.
6. Choose the number of B-channels allowed for this SPID. Delete 1. Select the SPID that you want to delete.
2. Click Delete. 3. Click OK.
Network DNs table
DN <system DN> This ISDN DN acts as the contact point for the loop to the system.
Call Type Voice Data Both
Defines the type of calls supported on the loop.
T-loops D-packet service
The D-Packet Service panel is the second tab of the loops panels.
Attention: D-Packet service is only available if your service provider provides this capability.
This panel enables you to configure D-Packet Service to T-loops. You must have both T-loops and S-loops configured on the same module to allow this feature. The following figure illustrates the D-Packet Service panel.
Figure 60 D-packet service (T-loops)
The following table describes each section on the D-Packet Service panel.
Add 1. Select the appropriate SPID (1 or 2). 2. Under the Details for SPID table, click Add. 3. Enter a network DN.
4. Click OK.
5. On the table, click in the Call Type field beside the DN you entered. 6. Choose the call type for the DN.
Delete 1. Select the SPID that you want to delete. 2. Click Delete.
3. Click OK.
Table 41 D-packet Service panel parameter values
Attribute Value Description
Associated loop X01-X04 Enable this service, only if you are installing devices that require this type of service.
Enabled D-packet Service
<check box> North American BRI loops can support two B-channels. The SPID may be the same or different for the channels.
Table 40 SPIDs and network DNs parameter values
S-loops assigned DNs
The Details for Loop panel for S-loops allows you to view which device records are assigned to a loop, and to add or delete a record from the loop. The following figure illustrates the Details for Loop panel.
Figure 61 Assigned DNs (S-loops)
The following table defines the fields on the Details for Loop panel.
TEI <digits> These entries identify up to eight terminal identifiers for the devices assigned to the S-loops. Your BRI service provider supplies these numbers, if they are required.
Actions
Add (SPID digits) 1. In the top frame, click the loop where you want to define D-Packet Service. 2. In the bottom frame, ensure the Enable D-packet service check box is selected.
3. In the Associated loop field, enter a defined S-loop. 4. Under the TEI table, click Add.
5. Enter a TEI. 6. Click OK.
