Table 7-1. Single Port Full T3 Bandwidth Application Example
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 OSU 300 for multiport operation. The OSU 300 supports up to
three port option cards (Quad DSX-1, V.35 or HSSI). These option
cards are hot-swappable and can be field installed. See the section
DTE Ports 2-4 (Expansion Slots) on page 2-5 for more information on
card installation. A configuration example of this application using
a Quad DSX-1 card is on page 7-7.
This application (shown in Figure 7-2 on page 7-3) supports two
subnet connections via two different routers, a video conferencing
connection, and a main frame data connection. The OSU 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.
