Included Highlights

Easy Access

Front, rear and side doors are equipped with key locks and padlock tabs. The side door provides controlled access to the protector panels. With a total capacity of 1000 lines, the Tellabs 52EU is designed for POTS or heavy broadband installations requiring optimal xDSL service card capacity.

Extend Connectivity

The Tellabs 52EU Remote Broadband Cabinet is an outside plant enclosure supporting Tellabs1000 Multiservice Access (MSAP) Channel Bank Assemblies (CBAs) with fan shelves, protector panels, charge/rectifier and batteries. The Tellabs 52EU cabinet enables service providers to cost-effectively deploy high densities of broadband services, such as ADSL and VDSL.

Optimize Thermals

The Tellabs 52EU incorporates the latest environmentally controlled design technology to meet broadband demands for hardened outside plant cabinets. It has been tested to GR-487 CORE and has a documented level of performance with respect to noise level, salt fog, transportation, dust and water intrusion. It can support up to eight Tellabs 1000 (MSAP) CBAs with fan shelves, protector panels, batteries, and a charge/rectifier.

Converge Services

Like all Tellabs cabinets, the Tellabs 52EU supports POTS, ISDN, special services, T-1, xDSL, Ethernet and fiber. The cabinet can be deployed in any network topology (point-to-point, star, tree), including integrated (GR-303, TR-08) and universal configurations (TR-57).
