Note that it is imperative that the Offender gives up the

line when the DCU needs to call. Failure to do so will be

detected and could result in a violation situation.

Outgoing Calls

The DCU calls the Monitor Center, either to report a violation

or to report its current status.

Performing an outgoing call

If the Offender tries to perform an outgoing call and hears a

sharp modem sound, the Offender must hang up the phone

immediately. This means that the central computer is trying to

call the DCU.

Note that the Offender should not attempt to use the

phone during the next 8 minutes.

During the conversation the Offender might hear a short tune

from the DCU. This tune indicates that the DCU needs to call

the central computer. In this case, the Offender should complete

his/her conversation as soon as possible to enable the DCU to

make its call.

Note that it is imperative that the Offender gives up the

line when the DCU needs to call. Failure to do so will be

detected and could result in a violation situation.
