Voice Trunking Gateway – Compressed Channel Bank

RAD’s Vmux-210 analog voice trunking gateway functions as a channel bank, providing LAN and compressed voice services over Ethernet and TDM networks.

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. 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.

Compatible with all types of VSATs, 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 economically extends analog lines and LANs to remote sites.

• Cuts bandwidth and leased line costs

• High-quality voice ensured during compression by state-of-the art voice codecs and in-house developed DSP technology

• More bandwidth-efficient than VoIP for voice-trunking applications

• Converges voice, fax, modem and data services

• Compact, scalable and simple to deploy

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.

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 RV-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.
