Voice Trunking Gateway
RAD’s Vmux-2100 voice trunking gateway
employs powerful voice compression
algorithms, reducing leased line costs and
increasing the efficiency of the IP network.
Vmux-2100 compresses up to 16 full E1/T1
lines (496/384 voice channels) over a single
E1/T1, serial or IP uplink, enabling enterprises,
mobile operators and service providers to save
costs by leasing fewer lines to transport their
voice payloads.
The Vmux-2100 is especially suited for satellite
connectivity, remote call centers, 2G and 3G
cellular backhaul, international voice trunking,
wireless Local Loop, and rural telephony. Vmux
may be used in narrowband applications,
wherever there is a need to minimize
bandwidth for voice transmissions, over any
media (for example, TDM or IP satellite links).
Voice compression reduces line costs
Vmux-2100 uses G.723.1, G.729A and G.711
voice compression algorithms for optimal cost/
performance. It maintains toll-quality voice
while achieving the highest compression ratio
for voice transmission over TDM and IP
networks. Voice activity detection and silence
suppression allow Vmux-2100 to dynamically
utilize bandwidth for voice traffic and fax or
modem relay, resulting in very efficient
bandwidth usage over fewer lines, while
signaling information is transmitted separately.
Uses less bandwidth than VoIP
TDMoIP capabilities improve bandwidth
utilization and provide a real migration path to
IP. Separate TDM and Ethernet uplinks enable
simultaneous transmission over both TDM and
IP networks. With lower overhead than VoIP
systems, Vmux frees 60 percent more
bandwidth for additional voice or data, which is
crucial on costly or limited bandwidth links.
Converged services save equipment and
maintenance costs
Network integration is the key to maximum
savings in the wide area network. Vmux-2100
converges voice, fax and Ethernet traffic over
the same network link. By combining voice/fax
capabilities with Ethernet data traffic over a
single delivery network, operators can save
significantly on the costs of running their
networks.
Space-saving unit
The compact, 1U-high Vmux-2100 is a modular
unit that can be installed in 19-inch racks. It
has the smallest footprint of any TDM voice
compression or VoIP product of equivalent
capacity. The unit can be configured with up to
four voice compression modules, up to four
channelized TDM modules and up to two power
supply modules. All modules are plug-in and
field-replaceable. The power supply and voice
compression modules are hot-swappable.
