- Standard GR300 Configuration Options. (replace R-1-C-K
Module in Standard Configuration), The following are plug-in modules which replace the
R-1-C-K in the standard GR300 configuration and continue to provide repeater capability.
- ZR310 Multiple Tone Panel. Functions as a community repeater tone panel. Includes a full portfolio of features such as 50 PL and 20 DPL user groups, courtesy tones, squelch tail elimination, high quality repeat audio, sensitive tone decoding and station ID.
- iSOR Basic Telephone Interconnect. The i5OR offers the same features as the proven i5O interconnect, providing maximum system control and highly reliable operations. It allows interconnection with the land-line telephone networks. Standard features include automatic call forwarding, call limit timer, mobile inactivity timer, automatic line leveling and long distance inhibit.
- ZR320 Interconnect With Selective Calling. With the addition of the ZR320, the GR300 becomes a single group repeater with full-featured telephone interconnect. These features include selective calling so that any radio can call another specific radio as well as the land-line telephone network, DTMF and Quik-Call 11 signalling. The ZR320 operates in simplex (vox) and semi-duplex modes and includes a wide variety of RSS or remotely programmed options.
- ZR330 Remote Telephone Interface. The ZR330 is for use
in remote areas where a land-line telephone network is not available. It provides
telephone service via radio by supplying an interface between a standard DTMF telephone
instrument and a radio. This remote telephone interface requires the use of an additional
repeater with the ZR320 at a separate base connected to the land-line telephone network.
The ZR330 communi- cates with the ZR320 connected to the land-line telephone network to
provide nearly transparent phone operation for rural or emergency applications.
GR300 Applications - Uni-Directional. Allows standard repeater operation, using only one transmitter and one receiver. Application: Provides added range for portables on widespread construction sites.
- Bi-Directional. Allows two groups on different frequency pairs within the same frequency band to communicate. Application: Temporarily joins two separate groups such as Civil Defense and Fire for emergency relief.
- Uni-Directional Crossband. Allows radios on one frequency band to monitor transmissions from another. Application: Provides the capability to monitor frequencies such as weather or road condition channels.
- Bi-Directional Crossband. Allows two groups operating
within different frequency bands to communicate. Application: Temporarily joins two groups
that normally operate on different frequency bands, such as public works and police, for
natural disaster situations.
