SIC-1BSV/SIC-2BSV

Introduction
The 1/2-port ISDN BRI S/T voice interface module (SIC-1BSV/SIC-2BSV) is mainly used to process
(receive/transmit and compress/decompress) the ISDN interface voice traffic. The interface(s) on the
SIC-1BSV/SIC-2BSV module is (are) ITU-T I.430-compliant, adopting pseudo-ternary coding,
providing 192 Kbps interface rate, and allowing the maximum transmission distance of 1 km (0.6
miles) in point-to-point mode. In the upstream direction, the SIC-1BSV/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 the voice packets from the TE device to the Internet through a WAN interface on
the router, thus implementing VoIP. The module has the following features.
•
A BSV interface supports two modes: user and network, respectively for connecting an ISDN
network and a TE device.
•
When a BSV interface works 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 control board to a WAN interface. The IP voice traffic received on a WAN interface is
forwarded through the CPU on the main control board to SIC-1BSV/SIC-2BSV, where the traffic
is decompressed and sent to the TE device.
