Data Channel Remote Maintenance Loop Around
Test (#109)
This non-destructive test verifies the integrity of the entire DATA-CHL (that is, the
software, dual port RAM, and hardware that comprise it). The test places a call
from arbitrary DATA-CHL and into target DATA-CHL to loop over the connection in
each direction, and it checks that the data received by one data channel is the
same as the data that was sent by the other.
By establishing a connection between two data channels across the TDM Bus,
this test also verifies the integrity of the TDM Bus and Tone-Clock circuit.
Tests #107, #108, #110, and #111 on the DATA-CHL maintenance object can help
to determine which data channel is defective.
NOTE:
If Error Code recommends busying out a CDR, System Printer, Journal
Printer, or PMS Link, restore each busied-out link to service before
concluding work on the problem.
