Abstract
Example management closures (110) enable incoming optical and/or electrical signals to be connected to one or more subscribers (109) via an electrical distribution cable (102). Termination connections within the management closure (110) are connected to active electronic equipment (131) for modifying and/or enhancing the incoming signals. However, the connections between the central office (101), the active electronic equipment (131), and a subscriber (109) need not be made until the subscriber requests a service upgrade. Accordingly, the closure (110) allows for simple and low cost installation of the closure (110) before upgraded service is needed.
Claims14
A method for providing upgraded service to a subscriber, the method comprising:
- providing a management closure suitable for being installed at a distribution point of a telecommunications network;
- installing termination blocks in the management closure, the termination blocks including insulation displacement contacts, wherein installation of the termination blocks includes terminating twisted wire pairs of at least one multi-pair active equipment cable to the insulation displacement contacts;
- and
- installing a multi-pair cable loop in the management closure, the multi-pair cable loop including a plurality of segregated groups of twisted wire pairs, the multi-pair cable loop having an intermediate portion where an outer cable jacket has been at least partially removed to provide access to the segregated groups of twisted wire pairs and end portions where the jacket is intact, wherein installation of the cable loop includes routing the jacketed ends of the cable loop out of the management closure and managing the segregated groups of twisted wire pairs on separate conductor trays within the management closure;
- wherein the twisted wire pairs of the cable loop are not cut during initial installation of the management closure, but are cut later at a time of an upgrade request and are then terminated to the termination blocks.
A method for providing upgraded service to a first subscriber using a management closure installed adjacent an intercept box through which a distribution cable extends, the distribution cable being electrically connected to a central office and to at least the first subscriber, the management closure for providing upgraded service to a subscriber, the management closure including:
- a closure body;
- a plurality of termination blocks disposed in the closure body, the termination blocks including a plurality of insulation displacement contacts,
- at least one multi-pair active equipment cable including a plurality of twisted wire pairs terminated at some of the insulation displacement contacts;
- a multi-pair cable loop disposed in the closure body, the multi-pair cable loop including a plurality of segregated groups of twisted wire pairs, the multi-pair cable loop having an intermediate portion and end portions, wherein an outer cable jacket has been at least partially removed from the intermediate portion thereby providing access to the segregated groups of twisted wire pairs, and wherein the outer cable jacket is intact at the end portions of the cable loop, wherein the jacketed ends of the cable loop extend out of the management closure;
- and
- a plurality of conductor trays disposed in the closure body, each of the conductor trays managing at least one of the segregated groups of the cable loop, the method comprising:
- receiving a subscriber upgrade request from the first subscriber;
- cutting a twisted pair of the distribution cable to form a first cut end that is electrically coupled to the central office and a second cut end that is electrically coupled to the first subscriber;
- connecting the second cut end of the distribution cable to the first twisted pair of the cable loop at a second of the end portions of the cable loop, thereby connecting the first twisted pair of the cable loop to the first subscriber via the distribution cable;
- cutting the first twisted pair of the cable loop within the management closure to create first and second cut ends of the first twisted pair;
- and
- connecting the second cut end of the first twisted pair to one of the twisted wire pairs of the multi-pair active equipment cable at the termination block arrangement.
