DTRK500 loop channel
A
forward release message has been sent but not acknowledged by a backward release.
Check the configuration of the trunk at each end.
loop = the loop number of the trunk which sent the forward release channel = the channel
number of the trunk which sent the forward release.
DTA205 loop e
The CI-1 firmware has encountered a problem. Refer to DTIOO9 for CI-1 microprocessor error
codes (e).
DTA205 loop 128
This error message may result from an attempt to use the software with DTI2 cards prior to
QPC915C or QPC536E. New functionality has been introduced in the DTI2 cards. The old
cards ignore attempts to use the functionality introduced in these new cards.

o print the last sent and received signal, use Overlay 80 - Call Trace. The following print format
is used:

The SENT bits indicate the steady state on the line once the pulse is complete. The RECV bits
indicate the last bit pattern received on the trunk channel.
