Distributed control channel

The Type-D trunking system uses a distributed logic system that does not use a dedicated control channel. All trunked channels can be used for voice traffic channels to be shared more effectively with a large number of users.

Up to 48 trunked sites connection over an IP network

Type-D multi-site trunking can have up to 30 repeaters (RF units) per site and up to 48 trunked sites can be interlinked over the IP network. An IDAS™ terminal radio user can communicate with other IDAS™ terminal radio users working under the interlinked trunked sites.*

* Up to 16 pre-programmed sites can be down-linked simultaneously for a group call.

Up to 60,000 individual ID and 60,000 group ID numbers

In Type-D multi-site trunking, the combination of prefix ID and individual ID (or group ID) codes is used as a unique identifier. The Type-D multi-site trunking can have up to 30 prefix ID codes per system and up to 2,000 individual ID codes and 2,000 group ID codes per prefix ID. In total, up to 60,000 individual IDs and 60,000 group ID numbers can be used in a system.

Automatic site roaming

When a user turns on a radio, or moves from site to another site, the radio automatically starts a hunt scan and registers the own ID information to the repeater site. No user interaction is required.

Fleet management

The fleet management function allows the system manager to control a user group in a fleet. Users can be divided in up to 5,000 fleets and the system manager can enable or disable the use of the system for any fleet.

Fleet management example
Alias name Prefix ID
Individual ID
Group ID
1 Security A 1 1–10,31–400 1–20 Enable
2 Taxi B 1 11–30 21–25 Enable
3 Bus C 2 1–30 1–30 Disable
4 Truck D 2 1001–1005 51–53 Enable
The system manager can enable or disable the use of the system for any fleet.
(On the example above, Fleet 3 is disabled)

Integrated system for clean and simple installation

Type-D multi-site trunking requires only the UC-FR5000 (#03) trunking controller which can be installed into the IC-FR5000 series repeater – no external server and no extra rack space is required.

ESN authentication

Type-D multi-site trunking can reject to register an unauthorized terminal radio to the repeater site by using the electronic serial number (ESN) or individual ID of the radio.

Over the air update

IDAS™ repeater sites can update terminal radios programmed content with new system information like added channels and new sites over the air without interrupting use of the radio.

Call priorities

Terminal radios can listen to a call of higher priority even in the middle of lower priority on-going calls in the order below.
(1) Emergency Call (2) Individual Call (3) Group Call

RS-MGR1 System Manager

When used with the RS-MGR1 system manager software, air time information, network connectivity/statistics and hardware status of the Type-D multi-site trunking repeater sites can be obtained using Syslog messages.

Application example

CASE1Intra-building and inter-building solution

Image Zoom

With an IDAS™ multi-site trunking, it is possible to have radio communications all the way from the basement to the top floor, all in stable digital audio. Already deployed LAN cables can be used in an in-building solution.

*Note: Private IP Network or VPN Tunnels through the Internet.
