T1/E1, T3/E3 and Multi-Line Voice Service Commercial Services over Cable HFC and Fiber Infrastructures

This paper discusses technologies and solutions available to multiple service operators (MSOs) for delivering commercial services, such as traditional T1/E1 and T3/E3 circuits or multi-line voice services, over their fiber and hybrid fiber coax (HFC) infrastructures.

In less than a decade, cable modem technology has brought broadband Internet connectivity and more recently residential VoIP services to millions of customers.

 

Building on this success, multiple service operators (MSOs) worldwide are seeking to expand their market to the lucrative business segment. Typical applications include Multi-Line voice access to the PSTN, voice trunking between existing enterprise PBXs, as well as T1/E1 and T3/E3 private and leased line services.

 

To complete their business service portfolio, MSOs require a cost-effective way to implement TDM-based services over their fiber and HFC infrastructures. Only then can they aggressively compete with incumbent and alternative carriers offering lucrative leased line and private line services.

 

A major technological challenge to wide-scale deployment of such a solution is the need to deliver high quality voice services that transparently support the rich features of the huge installed base of PBXs and work equally well with key systems, modems and faxes.

 

RAD Data Communications offers a range of solutions based on TDMoIP pseudowire and VoIP technology that deliver T1/E1 and Multi-Line Voice over fiber, cable and fixed wireless infrastructures. RAD’s IPmux, Vmux and Gmux product lines are totally transparent to voice system signaling, enabling users to maintain their existing investment in equipment with no need to retrain or hire new support staff.
