supports the high speed data connection requirements of the
routers (using the HSSI ports), as well as the V.35 data connection
requirements of the video conferencing unit and the main frame.
The bandwidth is split by the T3SU 300 to provide 18 Mbps for each
router, 1.5 Mbps for the video conference units, and 6 Mbps for the
main frames. See Table 7-2 for an example configuration of this
application.
