If the call is established, and you initialize the system, the call is restored.
However, maintaining the displayed information is not guaranteed.
If system initialization occurs after the A-CLID call is in the agent queue, the
ACD module must display the CLID information after the call is established.
If the cyclic redundancy check (CRC) fails, the call terminates without
displaying the CLID ("UNAVAILABLE" and "O-Route access code number -
Member number" for name and number display).
If data transmission stops halfway, the call terminates without displaying
the CLID ("UNAVAILABLE" and "O-Route access code number - Member
number" for name and number displays).
The system can receive, process, and display alphanumeric characters as
CLI information. No CLI information displays if the CO transmits information
in another format.
A maximum display of 20 digits and 27 characters is possible with this
feature.
When the call is tandemed to an ISDN/MFC trunk, only the first 16 digits
of A-CLID passes on.
This feature does not change the functionality of R2-MFC trunks. R2-MFC
trunks display the route access code number when the CLI information is
not available, and not the member number.
If the system receives unrecognized messages or parameter types, the call
terminates without displaying the CLID ("UNAVAILABLE" and "O-Route
access code number - Member number" for name and number displays).
The A-CLID feature delays the occurrence of the first ring. The terminating
set rings when the complete FSK message is received, or the software
times out waiting for the FSK message.
When a DISA call is abandoned, the CO trunks is busy for a short period of
time before disconnecting. This is characteristic of CO trunks.

Attendant Call Extension
If an attendant extends a call from an incoming A-CLID CO trunk, the
terminating set receives the analog CLI information.
