Abstract: A front facing line terminal block assembly for a telecommunications network has an external housing mountable to a frame and a field block housing pivotally mounted to the external housing. The field block housing mounts a field block bearing a plurality of wire connectors. The external housing is capable of accepting the field block housing. A first set of retention elements is capable of positively locking the field block frame in a first, retracted position. A second set of retention elements is capable of positively locking the field block housing in a second pivotally rotated position wherein it is rotated outwardly of the external housing. An access door is pivotally mounted to the field block housing.

Abstract: A frame connector assembly having a module field into which six pin alarm indicating modules can be inserted. The front face of the module field has six receptacles for each module, each receptacle associated with a respective one of the six module pins. The rear face of the module field has six pins for each module, each pin associated with a respective one of the six receptacles. The ground bus which interconnects all of the rear face ground pins of all of the modules in a given row follows a serpentine path. The module field receptacles are designed to make it difficult to insert a module with the pins reversed.

Abstract: A telephone distribution frame connector assembly for connecting incoming lines to inside equipment and comprises a module field block, a test field block and an equipment field block, and a frame member for mounting the field blocks to a telephone distribution frame. The field blocks are mounted to the frame member to define a generally rectilinear enclosure having one open side. An access panel is provided for normally covering the one open side of the connector assembly, and a panel securing arrangement is provided for removably, securely engaging a marginal peripheral portion of the access panel with a peripheral edge portion of the open side. One or more of the field blocks includes a plurality of ground terminals located interiorally of the enclosure thus defined. A common ground bus is electrically coupled to all of the ground terminals and an adjustable ground selection arrangement is provided for alternatively coupling the ground bus to one of a frame ground and an isolated ground.

Abstract: A side access panel and associated rear fanning strip for enclosing the otherwise open side of a telephone distribution frame connector assembly. The fanning strip interconnects a rear facing edge of the access panel to a rear edge portion of assembly without the use of fasteners. An engaging means such as a clamping strip may also be included as part of the access panel to engage a front facing edge of the assembly to provide a more secure mounting of the panel over the open side.
