    ABSTRACT: Operations messages sent between Operations Systems (OS's) and Network Elements (NEs) can be transported over dedicated links or over
    existing service links that provide an Embedded Operations Channel (EOC). In addition, EOCs may exist with the customer access network
    to provide NE-to-NE operations communications. The EOC resides within a digital signal format.

    This Technical Reference (TR) contains the view of Telcordia on generic requirements for EOCs. Two Digital Subscriber Line (DSL)
    specifications are defined that are encountered in the various transport architectures in the Integrated Services Digital Network
    (ISDN) Basic Access network.

    The first EOC interface specification defined is derived from the American National Standards Institute (ANSI) T1.601-1988. The
    second EOC interface addressed in this document represents the view of Telcordia on generic requirements for a broader EOC
    specification that would provide capabilities for transmitting send operations messages between the ISDN switch and network element
    line units that support performance monitoring capabilities.

    Revision 1 presents a clarification to the data format used for the MP-EOC Data Read and Data Write modes.
