SIC-1BSV/SIC-2BSV
Introduction
The 2-port ISDN BRI S/T voice interface module (SIC-2BSV) processes ISDN interface voice traffic.
The interfaces on the SIC-2BSV module are ITU-T I.430-compliant. They use pseudo-ternary coding,
provide 192 Kbps interface rate, and allow a maximum transmission distance of 1 km (0.6 miles) in
point-to-point mode. In the upstream direction, the SIC-2BSV module can be connected to a user
interface on an ISDN switch to receive and decompress, compress and transmit ISDN BRI digital
voice traffic. In the downstream direction, the module can be connected to a TE device to forward
voice packets from the TE device to the Internet through a WAN interface on the router to implement
VoIP. The module provides the following features:
• A BSV interface supports user and network modes for connecting an ISDN network and a TE
device, respectively.
• When a BSV interface operates in network mode, traffic is processed as follows:
 The digital voice traffic received on the BSV interface is compressed and forwarded through
the CPU on the main processing unit (MPU) to a WAN interface.
