DC5A and DC5ADD AMC to DMS signals
The following tables describe the sequencing signals exchanged between the
DMS switch and an AMC node during incoming and outgoing call processing.
Table 4-3 DC5A and DC5ADD incoming signals
Status
idle
seizure
delay dial
proceed to send
on-line signaling (DTMF)
call established
clear back
re-answer
call re-established
clear forward
blocking
Note: The AMC node requires no signal before the node can send digits if
configured as DC5A. DC5ADD requires delay dial and proceeds to send signals
that the DMS switch sends, before the AMC node sends digits. Delay dial must
be sent for a minimum period of 30 ms and within 2.5 s. Proceed to send signal
must be sent within 2.5 s of delay dial. The call established signal is not sent within
300 ms of the seize signal.

Status
idle
seizure
Note: The DMS switch requires no signal before the switch can send digits if
configured as DC5A. DC5ADD requires delay dial and proceeds to send signals
sent by the AMC node before the DMS switch sends digits. The system must send
Delay dial for a minimum period of 30 ms and within 2.5 s. Proceed to send signal
must be sent within 2.5 s of delay dial. The call established signal is not sent within
300 ms of the seize signal.
