ISDN BRI Voice on the Cisco MC3810 MOD-1
ISDN BRI Voice on the Cisco MC3810
Feature Summary
With the optional BRI voice module (BVM) installed, the Cisco MC3810 multiservice access
concentrator provides four ISDN Basic Rate Interface (BRI) ports for connection to ISDN PBXs
(private integrated services network exchanges, or PINXs). The BVM has four ISDN BRI ports for
voice traffic. Each BRI port supports two voice channels (ISDN B channels) and one signaling
channel (ISDN D channel). The BRI voice ports have the following features:
ITU I.430 BRI
Full-duplex S/T interfaces supporting 2 bearer channels and 1 signaling channel (2B + D)
Total of 8 simultaneous voice channels
LT-S mode—Line termination of subscriber lines from PINX, with port configured as network
termination (NT)
LT-T mode—Line termination of an ISDN trunk from an ISDN exchange switch, with port
configured as terminal equipment (TE)
Each port individually configurable as NT or TE
Configurable clock recovery and distribution
Figure 1 shows an example of an ISDN BRI voice network. In the example, PINX A is the master
PBX for the system and supplies clock for the BRI voice functions.

Benefits
The ISDN BRI voice capability in the Cisco MC3810 provides the following benefits:
Support for BRI digital voice circuits using QSIG signaling
WAN access from telephones connected through PINX equipment
