Vmux-210

Analog Voice Trunking Gateway

(Compressed Channel Bank)

Vmux-210 is a remote voice trunking gateway

for both IP and leased line TDM networks,

providing LAN and compressed voice services

for corporate applications that require a large

number of analog lines for POTS or fax

connection. It is a customer-located device that

complements RAD’s larger modular Vmux-2120

system equipped with E1/T1 voice interfaces.

Voice compression for analog lines

Vmux-210 compresses voice traffic and

transports it over a serial link, E1/T1 link, or a

10/100BaseT IP uplink. 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.

Voice activity detection (VAD) and silence

suppression

Voice activity detection (VAD) and silence

suppression allow Vmux units to dynamically

allocate bandwidth for voice traffic. Efficient

bandwidth usage leaves more bandwidth for

data transport. LAN data traffic can be

controlled with rate limiting.

The gateway is transparent to all signaling

protocols and telephony features.

Vmux-210 can be configured and monitored

via a local ASCII terminal, Telnet or

RADview-SC/Vmux.

Vmux-210 is a compact, 1U-high, 19-inch wide

unit that can be mounted in standard 19-inch

racks. The voice interface options include 12,

15, 24, or 30 FXS analog ports. The unit is

available with either AC or DC power supply.
