DCN IP gateway provides communication between subscriber devices of DCN and IPN Intercom and PA/GA communication systems, using the enhanced Armtel protocols, as well as their connection with other systems and devices via SIP protocol or ISDN PRI. The DCN IP-gateway enclosure can include up to 3 modules, which can differ by versions of built-in software.

Functional options of DCN IP-gateway module are determined by the version of installed
software:

• E1/IPN

Module of DCN IP-gateway with software E1/IPN is for integration of the digital operative-technological PA/GA communication systems DCN and IPN produced by Armtel

• E1/SIP

Module of DCN IP-gateway with software E1/SIP is for communication of the subscribers of the digital operative-technological PA/GA communication system DCN with the devices of SIP telephony, such as SIP-telephones and IP-АBX, as well as for arrangement of communication between DCN central exchanges via IP-network

• E1/FTP

Module of DCN IP-gateway with software E1/FTP is for arrangement at external FTP-server of the storage of audio information, transmitted via E1 stream from the digital operative-technological PA/GA communication system DCN. This storage is used for realiza-tion of special communication functions, performing record and playback of speech fragments.
