Technical specifications:

Gateway provides connectivity:

• 20 analog phones for two-wire subscriber lines (lines FXS);
• four-wire analog connection lines to connect to a private automatic branch exchange (PBX) (Line FXO);
• five devices enabled for Ethernet 10Base-T/100Base-TX;
• a device that supports the technology, Ethernet 100Base-FX;
• a personal computer (PC) through the RS-232
• an analog service with the TA local battery.

For the analog subscriber lines Gateway provides:

• the ability to install a voice connection with any local subscribers of the gateway and remote subscribers from other gateways
• reception rooms in the momentum and in the tone (DTMF) set
• the generation of tone for FXS lines and detection tone for lines FXO;
• the call forwarding service
• transfer of facsimile (fax transmission protocol is supported through VOIP - T. 38).

Gateway supports the following voice codecs:

• G.711 (A-Law, u-Law);
• G.723.1;
• G.729 a / b.

To improve the quality of the voice gateway uses algorithms for echo cancellation G.165 / G. 168.

For correct transmission of DTMF tones on IP-networks gateway supports the protocol RFC2833.

To establish a VoIP-connections on IP-networks, the gateway supports the following signaling protocols:

• ITU-T H.323 version 4 (read more - H.323);
• SIP RFC3261 2.0 (more - SIP).

Gateway has the opportunity to work as a central device for interoperability of other VoIP-devices (terminals , gateways, telephones, VOIP). This gateway supports the following protocols:

• H.323 Gatekeeper;
• SIP Proxy with the function of the Registrar (read more - SIP Proxy / registrar).

To allow for flexible adjustment of the registration plan gateway supports the numbering system E.164 public networks.

Power sypply:

- DC 27 V with a limit deviation of voltage from 18 to 36 V.
