2-13. USING THE CCIR MODE

The automatic link establishment protocol standardized by CCIR (Consultative Committee on

International Radio, currently part of the International Telecommunications Union) is a protocol that

provides services similar to the ALE protocol (see para. 2-12), except that it uses a different

addressing scheme, based on six-digit station addresses with support for four-digit addresses for

backwards compatibility.

In the CCIR mode, you can enable the SCAN mode. In the SCAN mode, the radio scans a specified

group of channels programmed into the radio set, in which case the radio can receive calls on any of

the scanned channels. The operator can however manually select the channel on which to transmit a

call.

To use the CCIR mode, it is necessary to configure directory entries (at least one). For more details,

see the Configuring CCIR Directory Entries section in Chapter 4.

In addition, to use the CCIR scanning mode, it is necessary to program CCIR groups, using the MRC.

The main services available with the CCIR protocol are as follows:

• Receive calls from individual transceivers, as well as groups and subgroups of transceivers

• Call individual transceivers, as well as groups and sub-groups of transceivers

• Transmit text messages, beacon calls, and emergency calls.
