BASIC OPERATION

LTR-Net and LTR Operation

The LTR-Net and LTR modes provide automatic channel selection and monitoring before transmitting. Special tones and display messages indicate busy and out-of-range conditions, and telephone calls can be placed almost as conveniently as with your home telephone.

Selecting a system selects a collection of up to 99 groups. Selecting one of these groups selects an ID code which determines the type of call (standard group, telephone, or special), the specific mobile or mobiles is being called (if applicable), and what calls are received. In addition, higher priority calls may be received (see page 45).

The LTR-Net operating mode provides the most operating features. Exclusive LTR-Net features include roaming and Unique ID and Directed Group calls. When operating in LTR-Net sites, calls may be made to mobiles in other sites as well as the current site. LTR-Net and LTR features are described starting on page 45.

Conventional Operation

In the conventional mode, selecting a system selects a conventional channel, and selecting a group selects the special Call Guard squelch coding (if used) and other unique parameters on that channel such as call indicator operation. The Call Guard coding determines the mobile or group of mobiles being called and also the mobiles from which calls are received (see “Call Guard Squelch” on page 51).

In the conventional mode, a busy condition is detected automatically if the Transmit Disable On Busy feature is used. Otherwise, it must be detected manually as described in “Monitoring Before Transmitting” on page 49. Unsuccessful access conditions cannot be detected with conven- tional signaling, so are not indicated by special tones or display messages. Refer to “Operation At Extended Range” on page 60 for infor- mation on how to determine if an out-of-range condition may exist.
