Connecting telephones and adjunct systems
Busy tone disconnect equipment for
non-U.S. installations
The customer-provided busy tone disconnect adjunct detects busy tone disconnects of
incoming calls on loop-start, 2-wire, analog trunks. In some non-U.S. countries where a G700 or
G350 Media Gateway is used, the PSTN sends busy tone as the disconnect signal. Therefore,
the S8300 Media Server, G700 Media Gateway, or G350 Media Gateway requires a busy tone
disconnect adjunct.
