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.
The following rules apply when selecting the card slots:
MISPs
• MISPs are inserted into the Core/Network Module for Large Systems
(Multi Group). Refer to the LD 22 printout to identify modules with
unused network card slots and to Table 2 for the card slots in these
modules that can house MISPs.
• An MISP cannot share network loop addresses with a Superloop
Network Card in the Large Systems. The MISP requires two network
loop addresses and one network card slot.
• An MISP supports a maximum of 8 BRSCs and two line cards.
