Abstract: A network interface device (NID) including a plurality of cavities beneath the base surface of the NID. Each cavity extends downwardly between the base surface of the NID and the bottom of the NID defined by bosses and extensions extending downwardly from the base surface. Each cavity provides sufficient space for additional electronics, such as a test circuit, to be housed in the NID. The test circuit is housed within the cavity and is electrically connected between the incoming telephone company line and the jack of a line module. The line module is mounted above the test circuit by mating connecting means on the bottom of the line module to cooperative connection means on the base surface.

Abstract: A cabinet for interconnecting and storing optical fibers. The cabinet includes a plurality of left side members and right side members, each of which extends generally horizontally. A plurality of trays are slidably situated in the cabinet between the respective left and right side members. Each tray includes a generally flat base and open sides. The open sides permit optical fibers to be introduced into the tray from any position along the side of the tray. A gap is defined between each side member and the side members immediately above and below it. Each gap extends between the entire length of each side member from the front of the cabinet to the back. The gap provides adequate clearance for fibers introduced into the trays to move along the length of the gap when the tray is slid in and out of the cabinet.

Abstract: A tray for storing and splicing optical fibers in a cabinet-type enclosure. The tray includes a base. Extending from opposite sides at the front of the tray are fiber entrances, through which optical fibers from a cable positioned outside the tray enter the tray. A fiber splice area in which the splicing of optical fibers can be performed is located in the front portion of the tray. A storage area in which the optical fiber are stored is located in the rear portion of the tray and includes a plurality of retainers that extend from the base of the tray. The retainers are located in positions such that when the optical fiber is stored in the tray, the retainers prevent the fiber from being bent beyond its minimum bend radius. Each retainer comprises a small tab that projects generally vertically from the base of the tray. The tray is slidably mounted within a mount. The mount includes left and right side rails that are slidably inserted into slots on the inner left and right sidewalls of the cabinet.
