RAD Unveils Remote Compressed Voice Channel Bank for Both IP and Leased Line TDM Networks

The new Vmux-210 analog voice trunking gateway from RAD Data Communications is a remote compressed voice channel bank 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.

The Vmux-210 supports up to 30 analog voice ports, while providing a second Ethernet port for user LAN connectivity. It dynamically and efficiently controls bandwidth allocation, leaving more bandwidth for data transport. When used in conjunction with the other Vmux voice trunking products, the Vmux-210 analog voice trunking gateway significantly reduces the number of leased lines needed to transport voice and data payloads.

The Vmux-210 compresses voice traffic and transports it over a serial link, E1/T1 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. A customer located device, the Vmux-210 complements RAD’s larger modular Vmux-2100 system equipped with E1/T1 voice interfaces.

Voice Activity Detection (VAD) and silence suppression allow Vmux units to dynamically allocate bandwidth for voice traffic. This results in efficient bandwidth usage, leaving more bandwidth for data transport. LAN data traffic can be controlled with rate limiting.

The Vmux-210 analog voice trunking gateway is a compact, 1U high, 19" wide unit that can be mounted in standard 19" 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.
