The cards are installed in the Core/Network Module or the IPE Module
for all 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, 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 eight 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. Figures 1 through 3, beginning
