VERIFICATION

Verification without an Upstream Device

Verify that the H2TU-R powers up. The following should occur:

•The front-panel ALM LED is a steady red.

•The LOOP LED is flashing green.

•If receiving a DS1 signal, one of the DS1 framing LEDs (ESF or SF) and one of the DS1 line code LEDs (B8ZS or AMI) is a steady green.

Verification with an Upstream Device

1Verify that the H2TU-R powers up.

•The front-panel ALM LED is a steady red.

•The LOOP LED is flashing green.

•If receiving a DS1 signal, one of the DS1 framing LEDs (ESF or SF) and one of the DS1 line code LEDs (B8ZS or AMI) is a steady green.

2Verify that the H2TU-R attempts to communicate with an upstream device (LOOP LED is flashing green). One of the following occurs:

•If an upstream device is successfully identified and the HDSL2 loop synchronizes, the LOOP LED lights a steady green.

•If upstream devices are not successfully identified, the H2TU-R continues to attempt communication (LOOP LED flashes green) until an upstream device is detected.
