Catalyst 6000 Family Voice T1 and Services Module
The Voice T1 and Services Module establishes the Cisco Catalyst® 6000 family as the most complete campus multiservice platform available, providing high-end T1 or E1 gateways to the Public Switched Telephone Network (PSTN) or legacy private branch exchanges (PBXs) and network-based voice services. The Catalyst 6000 family brings data, voice, and video integration onto the campus for fully integrated communications on every desktop. Campus multiservice networking, or convergence, provides voice support using the IP network infrastructure rather than the traditional PBX. This drastically increases the leverage of telephony spending into overall infrastructure spending, reduces capital and operational costs, and opens the environment to innovation by supporting new applications. (See Figure 1.) Cisco is using the Catalyst 6000 family to lead its customers to campus convergence. The Voice T1 and Services Module, also available in an E1 variant, introduces the following new features for campus multiservice networking: - Digital T1 or E1 PSTN and PBX gateways
- Transcoding (G.711, G.729a, G.723)
- Conference bridging
