ABSTRACT:
Redundant but independently operable data processors called encoders are arranged so that control of a particular recorder gathering billing data in a telephone switching system can be transferred while maintaining billing continuity for calls being handled by that recorder. More specifically, each encoder checks the validity of billing information received from each recorder. However, each encoder only transmits billing data pertaining to a designated group of recorders to a remote processor. When an encoder detects that it is not receiving valid data from one of its designated recorders, the control of only that designated recorder is transferred to the other encoder if the other encoder indicates that it is receiving valid data from that recorder. Moreover, the relinquishing encoder sends a message to the remote processor indicating that it is giving up control of the designated recorder, while the accepting encoder inhibits the transmission of information to the remote processor for a predetermined time interval and then transmits a message indicating that it has accepted control of the designated recorder. This delay ensures that the remote processor will receive the relinquish message before the acceptance message so that the continuity of processing billing data for calls handled by the designated recorder can be maintained.
