Vega Gateway Scenarios.

Examples are given in best faith – ensure that you check the capabilities of systems before

deploying them, especially the functionality of devices not designed and delivered by VegaStream.

7. TDM to / from VoIP converter

Aim: To allow existing manufacturers of TDM based equipment (switches / IVR systems etc) to
have a VoIP offering.

Many manufacturers of TDM equipment are being asked by customers about their policy on VoIP.
Other customers are more demanding and informing suppliers that a migration path to VoIP is
essential. It is expensive to integrate a full VoIP solution into a product ‘just because a customer
has asked’. Use of Vega gateways allows integration of VoIP to existing TDM equipment on an as
needed basis.

The Vega gateway connects to the E1, T1 or BRI interface of the existing equipment and can
receive calls and convert them to SIP or H.323; the Vega gateway can also receive SIP or H.323
calls and convert them to E1, T1 or BRI calls.

Telephony Network

• E1 Euro ISDN signalling and QSIG signalling is supported by Vega 400 and Vega 100

• T1 NI1 & NI2 signalling is supported by Vega 400 and Vega 100

• T1 Loop start, Ground start and Wink start CAS signalling is supported by Vega 400 and

Vega 100

• BRI Euro ISDN signalling is supported by Vega 50 BRI

• Analog connection is also possible (for details on analog connectivity see later section)

IP Network

• Use of SIP or H.323 is defined by the code loaded into the Vega gateway

User experience

• The user will now be able to use the functionality that they had achieved using TDM

connectivity over a VoIP interface

USPs

• Vega gateways are designed to support full system loading, so performance will not

degrade as the unit becomes fully loaded

• A Vega gateway solution is cheaper than a PC card based solution, and uses dedicated

hardware rather than general-purpose hardware.
