Key Features

• High density saves space;

increases number of protected cable pair per frame vertical

• Narrow block width allows large inter-vertical working space for fast, convenient jumper administration

• Front ground test point option saves labor and increases reliability; provides a convenient place to attach an alligator clip without reaching behind the connector

• Accepts industry standard protector modules to permit a wide module selection

• Gold-plated protector module sockets and test-field contacts provide superior electrical contact; eliminate noise problem

• Standard 50-pair 303-type test fields save costs; require no special gear; are compatible with other connectors for frame expansions

• Integral field-stubbing bracket saves costs; permits fast, easy field stubbing; needs no temporary mounting bracket

R355 Central Office Connector Description

The R355 is a 100-pair high-density connector used on central office main distributing frames. It measures 10.95-in. H x 4.10-in. W and extends 7.38-in. outward from the frame.

It accepts industry standard 5-pin protector modules.

Connectors can be factory stubbed with 22- or 24-gauge cable in 10-ft. increments, starting at 20 feet. The stub is complete with a moisture dam and grounding harness. The connector has a 6AWG grounding system, which is available with or without isolated ground and can be easily converted in the field.

The front-facing equipment field allows convenient wire termination. Front and rear fanning strips facilitate orderly jumpering, and highly visible pair-count identification.

Two front administered 50-pair 303-type test fields make testing easy.

The R355 meets or exceeds the specifications set forth in Bellcore TA-EOP-000164 and GTE GTS 8339 documents.

The R355 is RUS accepted for additions to offices where R355s have previously been purchased using RUS funds.

Application

The R355 protects personnel and equipment from abnormal voltages and currents on incoming cable pairs. It mounts on central office conventional distribution frames with 8-in. centers.
