Installing ISDN BRI hardware for line applications

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.
—End—
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 "ISDN BRI card location"
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.
•
An MISP supports a set of 4 SILCs or UILCs when not supporting a
BRSC.
•
An MISP can support both BRSCs and SILCs or UILCs at the same time.
If it serves one BRSC, an MISP can also support three line cards. If it
supports two or more BRSCs, an MISP can also support two line cards.
BRSCs
•
Install one BRSC for each IPE module.
•
With a BRSC configured, an IPE module can support a maximum of 15
line cards. These can be up to eight UILCs combined with any other
seven peripheral cards (including SILCs), or up to 15 SILCs.
SILCs/UILCs
•
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.
