Abstract
Described are a system and method of transmitting a time slot status message between nodes in a SONET network. One or more time slots in a SONET link may be allocated to provision a SONET circuit. Upon provisioning or de-provisioning the SONET circuit, a time slot status message may be transmitted to one or more non-participating nodes in the SONET network to indicate a change in status of one or more time slots of the SONET link.
