INTRODUCTION AND OPERATION
Unique IDs also permit individual mobile units to
be called using the special calls described in the pre-
ceding section. Calls can also be made to individual
transceivers using standard call Group IDs 1-239 if an
ID is assigned to only one transceiver.
1.15.3 GROUP IDENTIFICATION CALLS
The Group ID (1-239) is assigned to each LTR-
Net Home Repeater. A "standard" Group ID call is
accepted by a mobile if its Home Repeater and Group

phone Interconnect calls, UID calls and Directed
Group calls (Auxiliary calls). Telephone Interconnect
Calls are assigned a Token Group ID (240-247)
assigned by the repeater upon request from a mobile.
Telephone Interconnect calls, Unique ID calls and
Directed Group Calls all require the System and Sub-
scriber Manager/Call Processor to provide authoriza-
tion.
