POINT-TO-POINT MULTIPORT APPLICATION
When networking requirements call for sharing the bandwidth of a
point-to-point T3 circuit, additional data ports can be installed into
the T3SU 300 for multiport operation. The T3SU 300 supports up to
three port option cards (either high-speed V.35 or HSSI). These
option cards are hot swappable and can be field installed. See the
section DTE Port Interface Card Slots on page 2-4 for more
information on card installation.
This application (shown in Figure 7-2) supports two subnet
connections via two different routers, a video conferencing
connection, and a main frame data connection. The T3SU 300
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.
