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 or more ISDN DNs under
N0130943 02
