Vmux-2100 is a modular voice trunking gateway that compresses and transports up to 16 E1/T1 voice trunks over E1, T1 or IP links. Vmux-2100 employs G.723.1, G.729 Annex A and G.711 compression algorithms together with RAD's unique TDMoIP multiplexing to transmit up to 496/384 voice channels, including transparent CAS and CCS signaling, over a single E1/T1 or IP link. Vmux-2100 is a unique device that can provide compressed voice transmission over both TDM and IP networks, and can easily switch between them whenever this may be advantageous, ensuring a migration path from TDM to IP networks. Vmux-2100 uses voice activity detection and silence suppression techniques to allocate bandwidth only when it is required, thereby conserving bandwidth. The gateway detects, generates and relays DTMF/MFR2/MFC signaling. The Vmux system may be used in narrowband applications, wherever there is a need to minimize bandwidth for voice transmissions, over any media (for example, satellite, TDM or IP links). Typical applications include satellite connectivity, international voice trunking, Wireless Local Loop and rural telephony. Vmux-2100 is a compact, 1U high, modular unit that can be installed in 19" racks. The unit can be configured with up to four voice compression modules, a single main link module, channelized E1/T1 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.
