Method for multi-mode operation of a subscriber line card in a telecommunications system

Abstract

A method and system for decreasing the probability of blocked access to a local exchange carrier's telecommunications network comprises a multi-mode line card for determining whether a particular call is a voice or data call. If a call is determined to require data transmission, the line card assigns time slots for interconnection of the line card to a serving digital switch. If no meaningful data is received, no time slots are assigned. In this manner, time slots interconnecting the serving digital switch to a line card are established only if data or voice is being transmitted from a subscriber line.
