Analog Voice Trunking Gateway

RAD’s Vmux-210 analog voice trunking gateway functions as a channel bank that provides LAN and compressed voice services over Ethernet and TDM networks. The Vmux-210 analog voice trunking gateway serves enterprises requiring a large number of analog lines for voice telephony and fax, freeing bandwidth for LAN traffic.

Employing powerful voice compression algorithms as well as TDMoIP ® technology, the Vmux-210 analog voice trunking gateway can compress up to 30 analog voice ports, while providing a second Ethernet port for LAN connectivity.

Featuring a second Fast Ethernet data port and compatible with all types of VSAT interfaces, the Vmux-210 also serves as a cost-effective solution for broadband satellite communications. For offshore call centers and multi-site applications, the Vmux-210 analog voice trunking gateway economically extends analog lines and LANs to remote sites.

When deployed with other Vmux voice trunking products, the Vmux-210 significantly reduces the number of leased lines needed to transport voice and data payloads.

• 16:1 compression saves on Opex and frees bandwidth for data services

• High voice quality

• Dynamic bandwidth allocation using Voice Activity Detection (VAD) and silence suppression, leaving more bandwidth for data transport

• Reduces the number of leased lines needed to transport voice and data payloads, lowering operating expenses

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 connections. It is a customer-located device that is deployed with RAD’s larger modular Vmux-2100 system for the central office.

Vmux-210 analog voice trunking gateway compresses voice traffic and transports it over a serial link, E1/T1 link, or a 10/100BaseT Ethernet 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.

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.

Vmux-210 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.
