4 Description

StarVoice is a DSL technology-based device designed for small and medium-size offices

for simultaneous voice and data transportation over a single telephone pair.

The functionalities of analogue and ISDN ports are obtained thanks to the Broadband Loop

Emulation Service (BLES) mode describes in the ATM forum “AF-VMOA-0145.000”

standard, using the ATM AAL2 level for voice connectivity transportation.

This model uses an ATM virtual circuit to connect an Integrated Access Device (IAD) with

a Voice Access Gateway (VAG), which is the interface with traditional telephone public

exchanges.

Thanks to this technology StarVoice can deliver:

phones, group 2/3 fax machines, and analogue PBX’s;

⇒

up to 4 ISDN BRI ports to connect ISDN telephones, group 4 fax machines, ISDN

PBX’s, videoconference systems.

Data is transported using the ATM AAL5 level with one or more VC’s for Internet

connection or LAN to LAN connections, for example for corporate networks.

StarVoice is a router with routing and bridging functionalities for network management

optimization.
