The RAD Data Compressed Voice System (CVS) available from Microtel: features and benefits

Carriers and enterprises are looking for ways to reduce costs by transporting their communications traffic with higher bandwidth efficiency. This can be achieved by using state-of-the-art voice compression algorithms that maintain toll quality voice, and converging voice and data traffic over the same network links.

Benefits of this approach include:

• A reduction in bandwidth requirements with 16:1 voice compression while preserving voice quality

• Flexibility of network design achieved by supporting TDM or packet-based WAN with the same device

• Transparent signalling support, which reduces capital expenses by preserving

• Minimise effects of contention in the network

• investment in legacy telephony equipment

• No need for staff retraining, since all existing PBX features are maintained

• Reduction in operational expenses with simple installation and maintenance

• Addressing of business concerns with evolutionary rather than revolutionary solutions

Carriers use CVS to improve profitability of their existing infrastructure and generate new revenues by extending their reach into untapped markets. The VMUX product range provides inexpensive, compact voice compression equipment that works well over almost any infrastructure. Typical applications that can benefit include:

• Wholesale and retail telecommunications providers, who can reduce expenses with compact voice trunking gateways that provide 16:1 compression and support features such as Q.50, super tandem, bandwidth control, SS7, ISDN PR1, and DTMF/MFR2/MFC signalling.

• Cable operators and wireless service providers, who can offer E1/T1 voice/fax services over their hybrid fibre/coax or wireless networks.

• National carriers, who can deliver rural telephony services over satellite.

Enterprises use CVS and voice/data integration to satisfy growing voice and data requirements without incurring the additional expense of adding network resources. Operating expenses are further reduced when voice traffic is migrated from expensive TDM networks onto lower cost IP, Ethernet or MPLS networks. Sample applications include:

• Remote call centres with bulk voice trunking needs, who can reduce expenses on leased lines.

• Corporations, who can reduce inter-location network expenses by eliminating E1/T1 voice circuits while retaining all PBX features.

• Utility companies, who can simplify their networks with voice/data integration.

• Government and enterprises requiring fallback links for disaster recovery applications, who can deliver voice and data to mobile contact centres over satellite or IP VPNs (e.g. cable modems).
