NOTE: 1.
The number 1 BRI module is installed in the upper left corner of the BRI card.
The number 2 BRI module is installed below the number 1 BRI module, and
the number 3 BRI module is installed beside the number 2 BRI module.
2.
BRI cards are "hot-swappable"; that is, that you can replace a configured, run-
ning BRI card while the power is on. You may also de-program the BRI card,
install the card, and re-configure the card for another slot.
3.
Each BRI module can be configured with either line-side or trunk-side interfac-
es (all four circuits on a module must be in the same mode). Line and trunk
side interfaces are software-programmable (using CDE forms), and no jumper
changes are needed.
4.
If you deprogram a BRI card, remove the BRI card from the cabinet as soon
as possible. This action decreases the load on the BCC III.
5.
After deprogramming a BRI card, remove the BRI card from the slot BEFORE
installing a BRI card in another slot.
6.
The U bus can be converted to an S/T interface using an NT 1 where required.
7.
Use IMAT to obtain the BRI card’s maintenance logs. The Maintenance
module provides serial connectivity to the PC (IMAT) for BRI maintenance.
