2.2 Key Device Technologies

(1) Softswitch technology

(2) Program-controlled switching technology

In this device, program-controlled switching primarily handles voice switching, signaling processing, and related functions. The shortwave and ultrashortwave radio voice channels, fax channels, audio broadcast channels, analog telephone channels, and magneto telephone channels each constitute an independent 64K channel. Additionally, signaling processing and switching on the 2M interface support NO.1 and PRI signaling.

(3) Gateway technology

The device supports converged access of various dispatch terminals, providing access for shortwave and ultrashortwave radio voice, fax, audio broadcast, analog telephone, and magneto telephone, enabling conversion of various voice signals to IP.

(4) Interconnection trunk technology

The system needs to be compatible with softswitch IP networks and traditional TDM switching networks, enabling interconnection functions with SIP signaling interfaces (IP), E1 digital trunk interfaces, and FXO analog trunk interfaces.

2.3 Device Structure

The device features a 19-inch, 7U (with the fan unit occupying 1U height) chassis with 16 slots, of which dual power supplies occupy two slots and the remaining 14 slots are service slots for inserting various dispatch and terminal service boards.
