DESCRIPTION

•

Vmux-110 is a customer-located

device that complements the

larger modular Vmux-2100

system, fulfilling the need for a

low capacity remote voice

trunking gateway for both IP and

leased line TDM networks.

Vmux-110 is available with either

an E1 or T1 port for digital voice

channels, or four FXS ports for

analog POTS.

•

Vmux-110 compresses the voice

traffic and transports it over either

a serial TDM link, or a

10/100BaseT IP link. The device

employs G.723.1, G.729 Annex A

and G.711 compression

algorithms together with RAD’s

unique TDMoIP multiplexing,

including transparent CAS and

CCS signaling.

•

A second 10/100BaseT port is

provided for connecting a user

Ethernet LAN to the unit.

Together with Vmux-110’s integral

Ethernet switch, this allows

integrating the user LAN traffic

with the compressed voice, over a

single uplink (IP or serial) to the

network.

•

Voice Activity Detection (VAD)

and silence suppression allow

Vmux units to dynamically

allocate bandwidth for voice

traffic. This results in very efficient

bandwidth usage, leaving more

bandwidth for data transport.

•

By preventing packets from being

sent when no voice activity is

detected, the VAD mechanism

conserves bandwidth. The

improved bandwidth utilization

enables Vmux-110 to support a

higher number of channels than is

possible by using conventional

voice compression methods

alone. By performing TDMoIP

multiplexing and grouping the
