Availability: Discontinued

The Vega 50 6x4 gateway connects a range of legacy telephony equipment, including PBXs, ISDN telephones, the ISDN, analog phones and the PSTN to IP networks. The Vega 50 6x4 supports up to 24 analog ports, up to 16 basic rate ISDN channels on 8 interfaces or a mixture of port types and capacities. The Vega 50 6x4 is available factory configured in a number of different configurations, other configurations are available to special order.

The following gateway is configured as follows:

• 4 FXS + 2 FXO

Each BRI interface can be independently configured as network side or terminal side. The Vega 50 6x4 gateway can, therefore, be connected to a PBX and the ISDN simultaneously. This configuration provides:

• No disruption to the configuration of existing equipment
• Flexibility and choice for call routing
• Analog interfaces on the Vega 50 6x4 can be configured as 600R, 900R or CTR-21

Open, Non-Proprietary Interfaces

The Vega 50 6x4 BRI interfaces supports ETSI BRI. The Vega 50 6x4, analog interfaces support standard loop start signalling. The Vega 50 6x4 gateways have proven interoperability with a wide range of existing telecommunications and VoIP equipment.

All VegaStream gateways can support SIP, H.323 and T.38 fax. The gateway can be configured for different country requirements, such as tones and line impedance.

Service Provider Applications:

• Customer premises gateway
• PSTN gateway

Enterprise Applications:

• Enterprise VoIP networking

Lifeline PSTN Backup

Vega 50 6x4 variants equipped with FXS ports are also fitted with two FXO ports. When powered the Vega can route calls to or from these two FXO ports. Under power failure conditions the two FXO ports provide a hard-wired bypass to two FXS ports allowing PSTN calls to be made even under this failure condition.
