Integrated Power Management Scheme for Telecommunications Systems

The trend in telecommunications networks is towards fewer main switching centres hosting larger numbers of remote concentrators located near to the customer interface. This digital equipment will have low defect rates and the majority of telecommunications centres will be unattended by maintenance staff. The organisation of maintenance will evolve towards small mobile units directed from centralised operations and maintenance centres. This paper describes an integrated power management scheme (PMS) developed by British Telecomm (BT) for remote monitoring and supervision of DC power systems for digital switching and transmission within the UK. The application descibed is the power management scheme for use with System X, the BT family of digital switching exchanges. The PMS enables the operation and maintenance of the DC power system to be fully compatible with that of the associated telecommunications system.
