7 Daily Operating Instructions
The Dual Comms receiver is capable of receiving incoming calls from the monitoring center and enables
the offender to perform outgoing calls to the monitoring center or to emergency services.
7.1 Incoming Voice Calls
The Dual Comms receiver can receive incoming calls to its cellular modem. On receiving an incoming
call, the Dual Comms receiver sounds a ring tone.
Incoming calls include:
Calls from the monitoring center or officers.
Voice Verification Test calls (if the offender’s program includes voice verification).
If the Dual Comms receiver is connected to the offender’s landline, the line may be shared with a regular
telephone on which the offender receives regular calls from friends or family. Incoming landline calls do
not cause the Dual Comms receiver to ring.
Upon answering a call to their landline telephone, the offender may hear a slight noise on the
line during the first few seconds of the conversation. The offender should not be alarmed. The
Dual Comms receiver automatically interacts with each incoming call for the first few seconds.
If, during a conversation on the landline telephone, the Dual Comms receiver emits a short tone
on the line, it means that the Dual Comms receiver unit needs to communicate with the Offender
Management System. The offender should complete their current conversation as soon as
possible to enable the Dual Comms receiver to make its call. Failure to free the line could
register as a violation.
To answer an incoming call to the Dual Comms receiver’s cellular modem:
When the Dual Comms receiver sounds a ring tone, lift up the handset and press .
To hang up an incoming call to the Dual Comms receiver’s cellular modem:
Press and place the handset in its cradle.
7.2 Incoming Data Calls
Incoming data calls can be defined as a communication session between the Dual Comms receiver and
the Offender Management System’s communication gateway.
When the Offender Management System communicates with the Dual Comms receiver via the cellular
network, the receiver does not ring and the offender will be unaware of the communication session in
progress.
However, if the Offender Management System communicates with Dual Comms receiver via landline, the
offender’s telephone will ring and the Dual Comms receiver answers the call following a pre-defined
number of rings.
When monitoring center staff perform a download via landline, the offender should be
instructed beforehand not to pick up the phone when it rings.
The offender should be instructed that if they pick up their telephone and hear modem sounds,
they must hang up the phone immediately and not attempt to use the phone for 10 minutes.
