1.4.3 VG-1D1V and VG-1D2V Voice Gateways
Alvarion's Voice Gateways enable operators and service providers to offer end
users a combination of IP-telephony and broadband data services.
IP-telephony services are supported for standard analog phones or G3 fax
machines. The VG-1D1V has a single POTS interface, and the VG-1D2V has two
POTS interfaces. The Voice Gateways is built on the H.323 and SIP standards and
support both narrow (compressed) and wideband (uncompressed) speech codecs,
silence suppression with comfort noise, line echo cancellation and regional
telephone parameters. Class 5 services such as call waiting and 3-party call are
also supported.
Up to 3 telephones can be connected in series to each telephone port. Daisy
chaining of Voice Gateways enables the service provider to offer certain end users,
for example small offices, additional telephone numbers.
The Voice Gateway also supports Internet access or any other Ethernet based
services. The unit can be installed behind a router/NAT due to NAT traversal
support allowing signaling as well as voice packets to correctly reach Softswitch or
Gatekeeper for bi-directional call initiations. The Gateway can handle up to 16
simultaneous VLANs, enabling the operator to offer different services to different
end users behind the unit.
The Voice Gateways are designed for remote management and supervision using
either the built-in internal web server or SNMP.
The Voice Gateways are easily updated and upgraded as they support remote
software and configuration file download.
