1. What Does an MSAN Give You
Tuesday, April 13, 2010

2. Definition of an MSAN
A 'Multi-Service access node' or (MSAN) also known as MSAG or 'Multi-Service Access Gateway' is a device typically installed in a telephone exchange (although sometimes in a roadside serving area interface cabinet) which connects customers' telephone lines to the core network, to provide telephone, ISDN, and broadband such as DSL all from a single platform.
Typical outdoor MSAN cabinet consists of NarrowBand (POTS), BroadBand (xDSL) services, batteries with rectifiers, optical transmission unit and copper distribution frame.

Allows service providers to differentiate on wider content
Government subsidies
Ongoing national initiatives to support deep fiber access
Japan, Korea, China, Singapore, Malaysia, Australia and France
US Broadband Stimulus is North America’s first push
Reduced operational costs of maintaining legacy copper based services
Eliminates distance sensitivity and largely eliminates asymmetrical nature of services (bigger upstream for P2P and Online Gaming)
Less active equipment in the network to serve a large base of customers

Designed for an all IP future
Unlike traditional MSAPs, the Total Access 5000 is built around a next-generation Ethernet core.
The past year has clearly shown that carriers are swiftly moving towards Ethernet, recognizing that the advanced high bandwidth services they want to deploy aren’t scalable across an ATM or TDM infrastructure. As such, the ATM capabilities of existing MSAPs are being overtaxed, causing carriers to move towards Ethernet based platforms.
The architecture of the Total Access 5000 is ideally suited to meet these applications. With 10 Gbps per slot of total bandwidth available, even the most aggressive applications are easily supported. The distributed architecture of the Total Access 5000 also provides a scalable way to design and build a multi-service platform, but only pay for services as you need those line cards.
Several of our existing accounts also have the Total Access EMS deployed. The fact that the Total Access 5000 is integrated into their already deployed EMS/OSS eases integration and provides a competitive advantage against other products that aren’t already deployed in that customer’s network.
