Derived Pair MaintenanceDerived pairs from carrier/pair gain systems which utilize copper pair are shown as subsets of the physical pairs to which the systems are assigned. Selection of any physical pair used for a carrier system displays the derived pairs for the entire system. The plant detail information for a derived pair related to a subscriber is the same as physical pairs with the addition of the system name and the physical pair to which it is associated. Circuit lookup for derived pair is the same as physical circuit lookup as it relates to circuit id, the derived pair look up will be based on the physical pair and the derived pair number. Physical pairs assigned to carrier systems are encumbered through an assignment process to identify them as carrier system facilities. The system automatically generates a report when only one circuit is left on a carrier/pair gain system. This serves as notification to remove the carrier/pair gain system from the network. In the case of ISDN, SPID ID’s are accommodated in the system. |
