BRI Wiring charts
A BRI Card in Slot 4 uses loops 201 through 204. A BRI card 
in Slot 3 uses loops 225 through 228 (profile 1, 3, or 4) or 231-
238 (profile 2). Because a BRI-U2 Card has only two loops, it 
only uses the first two loop numbers 201-202 and 225-226, 
(profile 1, 3, or 4) or 231-232 (profile 2) when it occupies an 
ICS slot.
The loops appearing on a BRI card may be automatically 
assigned lines, or you can assign one...

Wiring the BRI network interface
A network interface provides the connection between the 
ISDN network and the Modular ICS.
If the card in the ICS is configured as a T-loop, the ICS is 
wired to the network connection using an NT1. 
See T reference points on page 58 for more information about 
the NT1.

The Modular ICS supplies the NT1 functionality to a U-NT 
loop, allowing a direct connection to the network. The 
connection may use a plug and jack, or may be directly wired.
Wiring for U-NT network interface  
The BRI-U Card does not use or provide optional power.
Some installations may not use a plug and jack for connections between the ICS (NT) and the network.
