A connector unit (21) for automatically terminating a digital data services (DDS) line whenever a mating modular plug (30) is not inserted into the connector. The connector utilizes a switchable DDS jack (25) that mates with the modular plug (30) for connecting a data-transmit line and a data-receive line of a DDS network (41) to a customer's equipment (45). The connector unit has a maintenance termination circuit (40) with terminating impedances (r, r1, C and C1) and diodes (D and D1). When the plug and jack are not engaged, the maintenance termination circuit is connected to the data-transmit and data-receive lines via the normally closed jack contacts (33 and 34). As the plug and jack are engaged, the plug abuts against and, as movement continues, increasingly opens the jack contacts, causing the maintenance termination circuit to be disconnected from the customer's equipment and to be connected to the DDS network. The diodes are oppositely polarized to provide a signature for testing proper installation of the connector unit. When connected to the DDS network, the terminating impedances provide electrical terminating loads which reduce network noise.

Apparatus for storing and organizing spliced optical fibers into one of a plurality of in-line and butt splicing configurations and for imparting sufficiently large curvature to the curved portions of such optical fibers present during storing and organizing to prevent damage to the optical fibers, and a cover for such optical fibers upon being stored and organized.

A modular jack assembly includes a bridging card having conductors for establishing the desired bridging connections. An insert carrying the connector wires of the jack is placed in the jack such that the wires are received in edge slots of the bridging card to provide the electrical connections to the conductors on the card.

An adapter for establishing electrical connections such as telephone or data line connections includes a face plate sized to fit through a corresponding aperture in a wall panel and a back plate larger than the aperture to abut the rear of the wall panel. A bracket is received about the face plate from the front of the panel. The bracket includes upper and lower projections which are received in corresponding aligned slots on the face plate for mounting the adapter to the face plate.
