Communication Manager Maintenance Object Repair Procedures
TBRI-TRK (ISDN Trunk-Side BRI Channel)
The TBRI-TRK maintenance object is a port on both the TN2185 Trunk-Side BRI circuit pack
and the MM720 BRI Media Module. The term circuit pack in the following description
refers to both the circuit pack and the media module.
The location on the TN2185 Trunk-Side BRI circuit pack is UUCSSpp designation.
The location on the MM720 BRI Media Module is designated by GGGVSPP. Consult local
records for the location and designation of the equipment rack where the Media Gateway is
mounted.
The TN2185 circuit pack contains eight, 4-wire ports that interface to the network at the ISDN S/
T reference point over two 64-kbps channels (B1 and B2) and over a 16-kbps signaling (D)
channel. The B1 and B2 channels can be simultaneously circuit-switched, or individually
packet-switched. Only one channel per trunk can be packet-switched due to PPE (Packet
Processing Element) limitations. The D-channel is either circuit- or packet-switched. Packet
switching uses the PPE to combine all D-channels into a single physical channel, 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 channels. The packet-switched channels support the LAPD
protocol and conform with the CCITT Q.920 Recommendations for D-channel signaling.
The MM720 Media Module provides 8 S/T ISDN 2B+D ports that interface to either the central
office or another PBX. The MM720 contains eight, 4-wire ports that interface to the network at
the ISDN S/T reference point over two 64 Kb/s channels (B1 and B2) and over a 16Kb/s
signaling (D) channel. The B1 and B2 channels can be simultaneously circuit switched, or
individually packet switched. Only one channel per trunk can be packet switched due to Packet
Processing Element (PPE) limitations. The D-channel is circuit switched. The circuit-switched
connections have a Mu-law or A-law option for voice and operate as 64Kb/s clear data
channels.

1. For additional repair information for the TN2185 circuit pack, also see TBRI-BD (ISDN Trunk-Side BRI
Circuit Pack) and TBRI-PT (ISDN Trunk-Side BRI Port). For additional repair information for the MM720
BRI Media Module, see MG-BRI (BRI Trunk Media Module) and TBRI-PT (ISDN Trunk-Side BRI Port)
2. A MAJOR alarm on a trunk indicates that alarms on these trunks are not downgraded by set
options and that at least 75 percent of the trunks in this trunk group are alarmed.
Note:
all tests that run on circuit packs are applicable to media modules. These
tests will abort with error code 1412. This error can be ignored.
