ISDN Basic Rate Interface Installation
• In each module, install a maximum of 15 SILCs, or eight UILCs
combined with any other seven peripheral cards (including SILCs). If 15
SILCs are installed, the remaining slots in the module may contain a
BRSC, a UILCs or non-ISDN BRI cards that do not need the - 48 V
power supply of the IPE module (this restriction is due to power supply
limitations for the module). If 8 UILCs are used, you may install any
other card which could reside in the IPE module.
• Group all SILCs, UILCs, BRSCs and the MISP that supports them in the
same network group to avoid using junctors for dedicated connections.
The figures that follow show typical module configurations.
Figure 1 shows the NT8D35 Network module.
Figure 2 shows the NT8D37 IPE module.
