10. Callback
10. 1. Callback
Caution: When using the Callback feature, this product must be connected between a
telephone and a direct Exchange line. This feature may not be used when the
EuroRoute is installed in conjunction with a PABX system.
The ACS has the ability, via a token, to drop the Exchange line side of the EuroRoute, while
holding the user side off-hook. When incoming ringing is detected, the EuroRoute finishes
processing the call and connects the user. Upon execution of the ACS token, the EuroRoute
drops the Exchange line side connection and starts a timer based upon the value specified in
the token (see table below). The EuroRoute starts to look for incoming ringing until it is
detected, or the timer runs out. If the timer runs out, number unobtainable tone is heard.
While the EuroRoute is looking for incoming ringing, it can generate a 400 Hz tone back to the
user at a one second on, seven seconds off cadence, until incoming ringing is detected, or the
timer has expired. Once incoming ringing is detected, the Exchange line is terminated, and the
next ACS token in the sequence is executed.
