The Maintenance Entity table. Each row in the table represents an ME. An ME represents a relationship between two MEPs, each configured with a single service instance. Configuring a Maintenance Entity Group End Point (MEP) at each of the DSAPs creates a Maintenance Entity (ME) to monitor that connectionless connectivity. The ITU-Carrier Code (ICC) and Unique MEGID Code (UMC) form the Maintenance Entity Group Identifier (MEGID) that is carried in CFM Messages to identify incorrect connectivity among Service Instances. A small integer, the Maintenance Entity Group End Point Identifier (MEPID), identifies each MEP among those configured on a single ME. This table uses two indices, first index is the index of the Maintenance Entity Group table. The writable objects in this table need to be persistent upon reboot or restart of a device.
