the related section.
2. Enter display errors and follow the associated repair procedures 
for any on-board DS1C-BD errors.
3. If the loop-back point is LB 1, replace connectors and cables between

Transmission through the path of the loop back is successful. TN1654 DS1 
facilities will display the round trip delay time in milliseconds in the Error 
Code field. The round trip delay time is defined as the length of time in 
milliseconds it takes for the firmware to receive the test pattern after it has 
been sent. This measurement is taken on the last DS1 channel tested.
