4. Install the S/T Interface Linecards (SILCs) and/or U Interface Linecards (UILCs) or
Basic Rate Signaling Concentrators (BRSCs).
5. Connect ISDN BRI terminals. This procedure comprises the following:
• Connect the system to the Main Distribution Frame (MDF).
• Cross-connect the MDF.
• Connect ISDN BRI terminals to the DSL.
• Initialize the ISDN BRI terminals.
Selecting the card slots
To install ISDN BRI cards, perform the following steps:
1. Identify all the slots that can contain the ISDN BRI cards. 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.
• LD 22 to print the system configuration and identify unused network card slots
to install MISPs
LD 22 REQ: prt TYPE: cfn
• LD 20 to list unused IPE card slots to install SILCs, UILCs and BRSCs
LD 20 REQ: prt TYPE: luc TN: l s
Table 1: ISDN BRI card location on page 16 lists the modules that can house ISDN
BRI cards.

2. Locate the card slots in the modules that house ISDN BRI cards. Group all SILCs,
UILCs, BRSCs, superloops and the MISP that supports them in the same network
group to avoid using junctors for dedicated connections.
3. For the Communication Server 1000E, make sure the MISP is in the same IPMG
as the BRI cards.
