Abstract
A universal line card architecture includes core circuitry for performing battery, overvoltage, ringing, supervision, coder/decoder circuit (CODEC), hybrid and test (BORSCHT) functions interconnected to a control processor and processing system. The control processor and processing system serve a plurality of line cards and are configurable to one or more of a plurality of subscriber loop standards in which the line card can operate. Upon receipt of instructions from a configuration system, the processing system configures line card and core network interface elements so that an appropriate subscriber loop standard may be associated with the line card identified in the provisioning request.
