Sangoma Vega 400 4 T1/E1 Digital Gateway

The Sangoma Vega 400 digital gateway connects IP networks with digital telephony equipment via T1 or E1 connections. The VEGA-VS0111-120 comes licensed to support 120 channels through 4 T1/E1 ports.

Sangoma Vega 400 Overview

All Vega 400 gateways are supplied with four E1/T1 interfaces which are always fully available regardless of the license which has been purchased. The unit is purchased pre–licensed to suit the initial requirements of the customer for the quantity of concurrent VoIP calls desired through to 120 VoIP channels. Future expansion is easily achieved in the field & can be provisioned by means of further licenses and expansion modules. Each E1/T1 interface can be independently configured as network side or terminal side. The Vega 400 gateway can therefore be connected to a PBX & the PSTN simultaneously. This configuration provides:

    • * No disruption to the configuration of existing equipment
    • * Flexibility & choice for call routing

 

The Vega 400 gateway incorporates an additional four RJ45 sockets and fails over to these during outages. This resource can be utilized to achieve hardwired connection from the PBX to the PSTN for instances when the Vega is installed between the two. Or alternatively to failover to a back-up Vega 400 & thereby providing dual redundancy.
