network interface. Up to three cards may be installed into any of
the T3SU 300 DTE port card slots.
Ethernet Bridge Card
The optional Quad DSX-1 interface card plugs into the card slots on
the rear of the T3SU 300. This card provides four auto-sensing 10/
100 BaseT Ethernet ports. The Bridge module provides LAN-to-
LAN connectivity using bridging over the WAN. Additionally, this
module acts as a LAN switch to provide Layer 2 Ethernet switching
between each of the ports on the module. Up to three cards may be
installed into any of the T3SU 300 DTE port card slots.
Even though the Quad DSX-1 interface card allows you to trans-
port T1 information, the T3SU 300 still operates the DS3 interface
in an unchannelized fashion. Therefore, your DS3 network provid-
er must supply you with an unchannelized, point-to-point DS3.
First generation T3SU’s (P/N 1200217L2 and P/N 1200217L4)

Second Generation T3SU’s (P/M 1202217L2 and P/N 1202217L4)
