Cut costs for 1/0 Digital Cross Connect Replacement and so much more!


Service providers are actively working to retire old 1/0 DCS, and D4 channel bank equipment that are notoriously out-dated and highly unreliable. These 1/0 DCS and D4 channel banks occupy tons of space and consumer large amounts of energy. Making matters worse is the fact that most of this legacy equipment is manufacture discontinued and thus is not supported, nor are replacement parts readily available.

Tellabs 1000 MSAP (aka T1000, DMAX, AFC, UMC) is a low cost 1/0 Digital Cross Connect, and D4 Channel Bank replacement satisfying network modernization initiatives. It can accept DS1s with multiple Special Service DS0s, and groom them into other DS1s mapped to or transported directly to another CO. Economics improve even more when existing Tellabs 1000 systems, which are already operationalized, are used to start eliminating the old manufacturer discontinued 1/0 DCS, and D4 channel bank equipment.

The Tellabs 1000 can aggregate, cross connect and transport all the different DS0s – plus, it can drop local DS0s or pass them through untouched. Best yet, the T1000 is a modern, fully supported access platform, with world-class Panorama element management software, which offers fast GUI-based provisioning, monitoring and alarming.

Reduced power and space requirements

One of our major North American network operator customers was able to collapse five (5) telco racks loaded with 25 channel banks of both D4 and 1/0 DCS systems into one (1) Tellabs 1000 MSAP system, utilizing one (1) telco rack. Basically, 200 circuits (e.g. DDS, E&M, ISDN, UVG, Special Services 2W/4W, FX, DID, ETO, PLAR) in 200 old plug-in cards were reconfigured into just 95 Tellabs 1000 plug-in cards. This new configuration saved the service provider energy, space and money.
