Troubleshooting the WAN

WPIM-HDSL Installed in CSX200

WPIM-HDSL is configured for either Full or Fractional T1 and the WPIM is not able to establish synchronization on Loop 1 with the remote HDSL circuit.

•Verify using QuickSET of Local Management that one of the WPIM-HDSL is involved in the connection is set to Master (Local) Timing and that the other one is set to Slave (Loop) Timing.

•Verify the use of proper cabling for the HDSL connections. Category 3 or Category 5 Unshielded Twisted Pair copper wiring is required. One pair (2 wires) for Fractional T1, two pair (4 wires) for Full T1. The presence of bridged taps and multiple wire segments connected together to form the loop may reduce the maximum distance usable between the Remote and Local devices. Wire gauge has an impact on the distance which can be supported as well. The maximum distance is 12,000 feet using 24 AWG wiring.

•Verify the gauge and condition of the wire. A trained line technician may be necessary to determine this.

•Verify that the distance between the Remote and Local units is less than 12,000 Feet.
