Test Features

The DDS/MR64 has a number of diagnostic tests available for troubleshooting problems.

Remote loopback with test pattern

Local loopback with test pattern

End to end test pattern

Remote terminal loopback

Local loopback

Remote loopback

The DDS/MR64 also responds to telephone company generated DDS diagnostic tests. An internally generated 5 11 test pattern can be used in combination with other test features to perform self-test functions.

Indicators

Six LEDs provide status information:

TM (Test Mode)

OS (Out of Service)

TD (Transmit Data)

RD (Receive Data)

CS (Clear to Send)

NS (No Signal
