VoIP Gateway K-1220 is designed to provide voice data for IP-data networks.

The gateway can be used in climatic conditions:

  • ambient temperature from 238 to 323 K (from - 35 º to + 50 º C)
  • relative humidity of not more than 98 % at 298 K (25 º C)
  • atmospheric pressure of 60 kPa to 113 kPa.

The weight of the gateway - no more than 18 kg

Dimensions:

  • Lengh - 490 mm;
  • Width - 490 mm;
  • Height - 300 mm

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.
