System and method for controlling an ancillary telecommunications device such as an echo canceller within a telecommunications system. The system and method include and involve a switching system that is configured to receive a call from a calling station and to route said call within said telecommunications system, and an ancillary telecommunications device that is configured to control a call processing parameter to affect the call. The switching system and the ancillary telecommunications device are coupled to each other via a channelized call data network. The channelized call data network is configured to communicate data corresponding to the call over at least one data channel. The ancillary telecommunications device may control the call processing parameter to affect the call based on a continuity test issued by the switching system to the ancillary telecommunications device prior to the call.

Call control of ancillary telecommunications equipment using continuity tests

To ensure the integrity of a telecommunications network provisioned with a distributed restoration algorithm (DRA), a communications network is provided for routing signaling messages such as DRA restoration and maintenance messages among the various nodes of the network. Thus, while data is sent among the nodes via the working links interconnecting the various nodes, signal messages are communicated among the various nodes by way of the independent communications network, which may be a wide area network. By reallocating the signal messages to a separate network, an efficient telecommunications network is effected.

The switching system and the ancillary telecommunications device are coupled to each other via a channelized call data network. The channelized call data network is configured to communicate data corresponding to the call over at least one data channel. The ancillary telecommunications device may control the call processing parameter to affect the call based on a directive issued by the switching system to the ancillary telecommunications device during the call. The directive is contained within at least one channel of the channelized call data network. Additionally, the channelized call data network may be completely used for call processing and call payload transport even after the ancillary telecommunications device operates as directed (e.g., activates, deactivates, etc.) during the call.

Intra-call control of ancillary telecommunications equipment

A system and method for restoring communication between at least one pair of nodes in a network. Distributed intelligence is provided by messaging between adjacent nodes in the network. The messages in combination with user-configurable timers and rules provide fault isolation, forward flooding, reverse linking and connection.
