Typical Configuration

The IDM Integrated Multiplexer can support up to 12 wireless radio devices, including HF (shortwave), VHF (UHF) single-sideband radios, 350M and 800M cluster two-way radios.
The trunk interfaces can be:

1. GSM/CDMA interface
2. WAN port supporting electrical interface (RJ45) or optical interface (FC) (for IP phone access channel)
3. Standard telephone trunk interface
4. Standard magneto interface or 2100Hz magneto interface
   The default number of interfaces for connecting standard telephones or wired intercom terminals is 20 (10 per module).

Functional Description

1. Full intercom capability among all wired intercom terminals
2. All wired intercom terminals and telephones can monitor and speak to any one or multiple wireless clusters
3. Extension phones can dial external calls via standard telephone interface, GSM/CDMA, or IP trunk
4. Any two or more wireless radios or clusters can be bridged
5. Supports group call function: when an external call arrives, all phones in the same group call ring simultaneously; any phone that answers stops the ringing of others. If two or more external calls arrive simultaneously, the highest priority call is answered first, and other phones continue ringing
6. External calls are always answered in priority order; for calls of equal priority, they are answered in the order of ring arrival
7. Typically, wired intercom terminals have higher priority than internal phones; high-priority users can interrupt low-priority users' cluster transmission rights
