iBX2000 Gateway Equipment

DT60 (Digital Trunk Gateway) is the interface between the system and the public switched telephone network. It provides subscribers with connection to PSTN in Mode E1, realizes the call-out services of internal subscribers of the system, and fulfills the shifting from DSS1 and V5 signaling to H.323 protocol. Each DT60 provides two optional E1 connections. Multiple DT60s can be simultaneously overlapped in the system.

     DT60 Functions

• Voice prompts supported by the computer operator function to guide the subscriber to complete an incoming call.
• Basic network protocol functionality: TCP/IP and DHCP protocols.
• The H.323 protocol functionality covers H.225 call control signaling protocol and RAS protocol, H.245 logic channel control signaling protocol, RTP/RTCP protocol, etc.
• Voice/fax/data functions include voice coding and decoding, echo suppression, mute compression, T.38 real-time fax, etc.
• Network management and maintenance functions include system configuration, failure alarm, system testing, data download, etc.

AT20 (Analog Trunk Gateway) is the interface between the system and the public switched telephone network, which provides subscribers with connection to PSTN in the loop trunk mode, realizes call-out services of internal subscribers of the system, and fulfills the conversion of trunk signaling to H.323 protocol. Each AT20 provides 20 loop trunk connections and multiple AT20s can be simultaneously overlapped in the system.

AT20 Functions

• Occupation and release of trunk interface, ring test, DTMF number receiving, Caller ID function, etc.
• Basic network protocol functions: TCP/IP protocol, DHCP protocol, etc.
• H.323 protocol functions: H.225 call control signaling protocol and RAS protocol, H.245 logic channel control signaling protocol, RTP/RTCP protocol, H.450 supplementary service protocol, H.235 security protocol, etc.
• Voice/fax/data functions include voice coding and decoding, echo suppression, mute compression, T.38 real-time fax, etc.
• Network management and maintenance functions:
• The system realizes management and maintenance of the analog trunk gateway through the network management protocol, chiefly covering configuration, alarm, test and download functions. AT20 also supports local setting via serial interfaces.

AS20( Analog Subscriber Gateway) Abundant IP telephone deployment, traditional analog voice equipment and line resources are available at the current stage and the terminals enjoy advantageous position in terms of price. AS20 enables subscribers to fully leverage their existing telephone cabling and phone set resources for connection of analog subscribers to the system. Each AS20 offers 20 lines of analog subscriber connections and the system can select the quantity of AS20 to be used depending on the number of subscribers.
