Nortel S/DMS Express Platform Support

The S/DMS TransportNode OC-3 Express from Nortel is a late update to its OC-3 platform that provides cost-effective SONET transport vehicles for low- to moderate-capacity environments.

The Nortel S/DMS Express allows carriers to boost support in environments where voice and data traffic from multiple CSAs terminate in a central hub. While this was initially a focus in urban environments, providers have seen cost savings and enhanced support in rural, residential, small business and suburban deployments as well.
