    Line Loopback This test allows the loop interface (LINE) section of the local T3SU 300 to be tested from the remote T3SU 300 over the actual T3 circuit. Testing from the remote end of the circuit is performed by using a 511 test pattern or DTE data generated by the remote host.

    DTE Loopback This test is used to verify proper operation of the link between the T3SU 300 and the terminal equipment. During this test, all data sent by the terminal equipment is looped back to the terminal equipment. A block diagram illustrating the loopback point and the signal path is shown in Figure 6-8 on page 100.

    44.2 Mbps data over unchannelized T3 circuits. In the application shown in Figure 7-1, the T3SU 300 provides network connectivity for a router running at 44.2 Mbps. The data is frame relay and the unit is SNMP-managed via the local Ethernet.

  • Page 110: 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 (Quad DSX-1, V.35, or HSSI). These option cards are hot swappable and can be field installed.

    FRACTIONAL T3 CARRIER APPLICATION When network providers want to provide service at rates less than full T3, T3SU 300 units can be used in pairs for deploying sub-T3 rate services. In this application example (shown in Figure 7-3 on page 113), a carrier provides fractional T3 access at 8 Mbps for internet connectivity.
