Internal Call State unsolicited response

This unsolicited response is sent when the internal call state of the CM52 changes. The call state is based on
the use of a traffic channel. This is important because voice, data, SMS, and OTAPA can all use the traffic
channel. As a result, SMS messages can produce call state unsolicited messages.
The format of the unsolicited response is:
*EUNSOL: CALL STATE,<state_name>
Parameter
<state_name>
IDLE
ORIGINATION
TERMINATION
CONNECT

Indication of Service State unsolicited response

This unsolicited response is sent when service is initially found. When service is initially found, the scanning
may or may not continue. If scanning needs to continue, there may be additional SERVICE STATE messages
if a more preferred service is found. When scanning is complete, the SERVICE message is provided with all
the details of the serving system.
Depending upon Carrier-specific scanning requirements, it is possible to be told that service is found only to
receive a second message indicating no service. This occurs when service is found, but according to Carrier
rules that service is not be allowed. As a result, the module indicates that the invalid service was dropped.
For example, this might occur when a requirement by Verizon states that no PCS service can be used if it is
not in the PRL. The system acquisition records indicate service to PCS channels. Therefore the module could
find PCS service, only to find out the service is not listed in the PRL.
If service is NOT initially found, the NOSERVICE state is not reported. The NOSERVICE state is reported
when service is lost.
The format of the unsolicited response is:
*EUNSOL: SERVICE STATE,<service_state>
Parameter
