Busy tone disconnect equipment for

non-U.S. installations12

The customer-provided busy tone disconnect adjunct detects disconnects of incoming calls on loop-start, 2-wire, analog trunks. In some countries outside the United States, the PSTN sends tones in the voice band instead of line disconnect signals. Figure 39 shows typical connections.

NOTE:

The busy tone disconnect feature is not currently supported on a

G700 Media Gateway.
