5.4.2 Analog Line
Analog trunks can be provided within the systems in the following ways. In all cases the physical ports are
labeled as Analog. For full details of installation refer to the Avaya Branch Gateway Installation manual.
· Using ICLID
The system can route incoming calls using the ICLID received with the call. However ICLID is not sent instantaneously.
On analog trunks set to Loop Start ICLID, there will be a short delay while the system waits for any ICLID digits before
it can determine where to present the call.
· Line Status
Analog line do not indicate call status other than whether the line is free or in use. Some system features, for example
retrieving unanswered forwards and making twinned calls make use of the call status indicated by digital lines. This is
not possible with analog lines. Once an analog line has been seized, the system has to assume that the call is
connected and treats it as having been answered.
· Dialing Complete
The majority of North-American telephony services use en-bloc dialing. Therefore the use of a ; is recommended at the
end of all dialing short codes that use an N. This is also recommended for all dialing where secondary dial tone short
codes are being used.
· Ground Start
This type of analog trunk is only supported through the Analog Trunk external expansion module.
