2.1Subscriber ID Numbers/Paging Code Numbers
SmarTrunk II modes (Radiotelephone and Fleet Dispatch) are a function of subscriber identification programming.
Each subscriber in a SmarTrunk II System may be assigned two Subscriber ID Numbers. Subscriber ID numbers are similar to a telephone number. This is the number a landline or radio caller uses to contact the subscriber. As a security measure, this number is aliased to another number (Paging Code Number) for over the air signaling. This security measure insures that a radio listener cannot correlate any of the over the air signalling with a number dialed. The Paging Code is expected to be a confidential number known only by the System Operator/Manager and associates that program the subscriber equipment. There is no requirement for the subscriber to have knowledge of the Paging Code associated with the equipment in use. The associated Subscriber ID Number provides sufficient subscriber information necessary for all SmarTrunk II operation.
