Centralized control channel trunking

The Type-C trunking system uses a centralized control channel system. The control channel is independent of the traffic channels and continuously transmits a control signal. The Type-C trunking system is suitable for controlling a large number of users and congested traffic channels.


Message trunked and transmission trunked

The Type-C trunking system can set to either the message trunked or transmission trunked method. The message trunked method can provide quick response in a series of calls, while the transmission trunked method can allocate the best channel resources to all users.


Call queuing

If all traffic channels are busy, the user's call request is automatically stored in the call queuing until a traffic channel is available. The system sends a beep sound to notify when a traffic channel is available.


Eight priority levels with preemption

The Type-C trunking system can give priority levels to the users or some type of calls (such as a dispatcher or emergency call) in the call queuing. According to the priority levels, the priority user or call can use the channel prior to other non-priority users.


Four priority monitor IDs

When a call is received from a priority user (such as a dispatcher) while you are talking with another non-priority user, the system enforces you to end the call and switches the channel to the priority call. Important calls will not be missed.


Fail-soft mode

If there are any problems or failures within the system, the repeater site will try to work in the conventional mode and will continue basic communications.


Up to 48 site trunking

The Type-C trunking system can have a maximum of 30 (local) or 48* (regional) sites trunking, wide area roaming and calling service with an IP network connection. A transceiver can communicate with other transceivers registered to the interlinked trunked sites.

*
Maximum number of group call sites is 16 sites for Unicast and 48 sites for multicast.


Up to 60,000 group ID and unit ID capability

The maximum 60,000 Group ID and Unit ID capacity is sufficient for large organizations and multi-user system sharing. A capacity of up to 3,000 Unit ID and group IDs provides ample unit and fleet organization capabilities for single-site trunking systems.

Type-C and Type-D Trunking. The Difference?

Users are on standby on the control channel and are allocated to a traffic channel when a call is made or received.



• Small to large enterprise-sized scalable system
• Similar to analog MPT 1327 trunking
• Call queuing
• Call priority
Users are on standby on any of the home channels in the system, which also become traffic channels during a call.
(Dedicated channel for control is not required)

• Effective distribution with fewer channel resource
• Cost-effective for small to medium-sized system
• Similar to analog LTRTM trunking

All stated features, appearances and specifications may be subject to change without notice.
