SOFTWARE INSTALLATION FOR ISDN BRI
Four steps, all in LD 27. The MISP requires a superloop. Note also, the MISP to SILC association is in software only (in the DSL Data Block). There is no physical connection between the two cards. Similary, a SILC (in an IPE shelf) can share a MISP with up to 3 other SILCs which may (or may not) be on the same loop.

NOTE: If the PBX does not recognize the card automatically, the MISP card/loop may have to be enabled via ENLL or ENLC in LD 32 to force activation and software download.
SET PROGRAMMING:
The most important issue is that the Service Profile ID #1 (SPID) in the set must match the SPID assigned in LD 27 (TSP). You will get a network registration error message on the sets display if this does not match. You will need to set/confirm the following:
- Active Network Port - ISDN (not PSTN)
- Service Profile ID (SPID) #1 - Must match TSP as mentioned above.
- Directory Number (DN) #1 - 4 digit PBX extension number.
- Leave SPID #2 and DN #2 empty
- Feature Code - Standard.
- Initial Mode - Change to Traditional (factory default: Secure Only).
WIRING the set:
An ISDN phone requires an RJ-45 cord connected to an RJ-45 wall jack, and uses two pairs from the PBX (SILC TN). The wiring is standard straight-through two pair (T-T, R-R for both pairs).
If the wiring is good, and if the set has been programmed correctly, you should get a dial tone and be able to make calls to verify install. From PBX hyperterm, STAT for the TN in LD 32 should show DSL=ESTA and L1=UP indicating a link layer established with the set.
If the wiring is faulty, the ISDN set will fail network registration, and LD 32 STAT will show
DSL=IDLE and L1=DOWN. Check cross-connections and wall jacks!!

Install ISDN BRI hardware for line applications
The following lists the procedures for installing ISDN BRI hardware for line applications. Meridian 1 must already be installed and operating according to the instructions in System Installation Procedures (553-3001-210) before
performing these procedures.
For a successful installation, perform these procedures in the order listed below:
- Select the card slots where the ISDN BRI cards will be located
- Remove the module cover for card installation
- Install the MISPs
- Install the SILCs
- Connect the ISDN BRI terminal equipment (phones).
Select the card slots
To install ISDN BRI cards, perform the following steps:
1. Identify all the slots that can contain them. First identify the modules with unused network and peripheral card slots and then remove the covers from the identified modules.To identify the modules, use the following Print Programs. Table 1 lists the modules that can house ISDN BRI cards.
- LD 22 to print the system configuration and identify unused network card slots to install MISPs
- LD 20 to list unused IPE card slots to install SILCs
ISDN BRI card location
2. Locate the card slots in the Meridian 1 modules which can house ISDN BRI cards. Group all SILCs, superloops and the MISP that supports them in the same network group to avoid using junctors for dedicated connections.
The following rules apply when selecting the card slots:
MISPs
MISPs are inserted into the CE/Network Module for options 51C and 61C, and the Network Module for options 81C. Refer to the LD 22 printout to identify modules with unused network card slots and to Table 1 for the card slots in these modules that can house MISPs.
| Modules | Supported Systems | SILCs | MISPs |
|---|---|---|---|
| NT5D21 Core/Network Module | 51C, 61C, 81C | - | Network slots 0-7 |
| NT8D35 Network Module | 81C | - | Network slots 5-12 |
| NT8D37 IPE Module | All systems | IPE slots 0-15 | - |
- An MISP cannot share network loop addresses with a Superloop Network Card in options 51C, 61C, and 81C. The MISP requires two network loop addresses and one network card slot.
- An MISP supports a set of four SILCs
SILCs
- SILCs are installed into the IPE card slots of the CE/PE Module and/or theIPE Module for option 21E. They are installed into the IPE Module for all other system options. Refer to the LD 20 printout to identify modules with unused peripheral card slots
- In each module, install a maximum of 15 SILCs
- Group all SILCs and the MISP that supports them in the same network group to avoid using junctors for dedicated connections.
