MIM-2BSV/MIM-4BSV

Introduction
The 2-port (4-port) ISDN BRI S/T voice interface module MIM-2BSV (MIM-4BSV) is mainly used to
process ISDN voice traffic. In the upstream direction, it can be connected to user interfaces 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 TE devices to allow their voice traffic to be
forwarded through a WAN interface on the router to the Internet, thus implementing VoIP. The
interfaces on the MIM-2BSV/MIM-4BSV module are ITU-T I.430-compliant, adopting pseudo-ternary
coding, providing 192 Kbps rate, and allowing the maximum transmission distance of 1 km (0.6 miles)
in point-to-point mode. MIM-2BSV/MIM-4BSV has the following features.
•
The BSV interfaces support 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 MIM-2BSV/MIM-4BSV, where the
traffic is decompressed and sent to the TE device.
