The introduction of digital loop carriers (DLC) has made testability levels more complex. A six-step tune-up procedure for UDLC based systems is described. The first step is verifying the operation of the pair gain test controller. The second is surveying DLC systems. The third involves verifying test system availability. The fourth is examining metallic test access to customer lines. The fifth is assessing the accuracy of the line record database. The last involves updating the training of DLC test personnel., This six-step process could resolve your test system and dispatching problems Testing POTS lines and assuring the accuracy of the tests used to be much easier. When a line test [...]

Hybrid networks made of optic fibers and coaxial cables are enabling telephone companies to perform real-time, continuous monitoring of the local loop from the central office to the customer's network interface unit. In addition, such smart networks also allows remote testing and provisioning. The shift from twisted-pair copper star networks curbs maintenance costs and labor, especially since the networks are the ones that report problems to the carrier., Smart networks put a new spin (cycle) on remote testing and monitoring. The loneliest guy (or gal) in town. What a great thought--networks built like washing machines. Not clean--reliable. So [...]

Investing in modern telephone systems is another way of improving efficeincy in the accounting process. These systems are equipped with the latest innovative features in telecommunications and offer less maintenance and repair costs. A wide array of telephone systems offered by companies such as British Telecom, Mercury, AT&T, Energis, Ionica and Sprint. Telephone systems that offer a range of service capabilities include Rhapsody Rio from Securioir Systems, Foundation Systems' Eclipose Call Management and new entrants Monarch, Senator, Marquis, Octara, Pentara and Emblem. These systems facilitate the overseeing of the accounting process, which in turn enables accountants to provide a better quality of client service.

Boosted by competition and the spread of microcomputer systems to small businesses and branch officers requiring dedicated links, demands for private line telecommunications services are expanding rapidly. These fast moving [...]
