BRI Circuit Pack
The TN2185 ISDN trunk-side BRI circuit pack contains eight, 4-wire ports that interface to the
network at the ISDN S/T reference point over two 64 Kb/s chels (B1 and B2) and over a 16Kb/s
signaling (D) chel.
The B1 and B2 chels can be simultaneously circuit-switched or individually packet-switched.
Only one chel per trunk can be packet-switched due to PPE (Packet Processing Element)
limitations. The D-Chel is either circuit-switched or packet-switched. Packet switching uses the
PPE to combine all D-chels into a single physical chel, which is then routed via the
concentration highway to the NCE (Network Control Element) and then to the TDM bus. The
circuit-switched connections have a Mu-law or A-law option for voice and operate as 64-kbps
clear data chels. The packet-switched chels support the LAPD protocol and conform with the
CCITT Q.920 Recommendations for D-chel signaling.
