Description: This object contains the MTA Admin Status of this device. If this object is set to 'true', the MTA is administratively enabled, and the MTA MUST be able to interact with the PacketCable entities, such as CMS, Provisioning Server, KDC, and other MTAs and MGs on all PacketCable interfaces. If this object is set to 'false', the MTA is administratively disabled, and the MTA MUST perform the following actions for all endpoints: - Shut down all media sessions, if present. - Shut down Network Control Signaling (NCS) signaling by following the Restart in Progress procedures in the PacketCable NCS specification. The MTA must execute all actions required to enable or disable the telephony services for all endpoints immediately upon receipt of an SNMP SET operation.

Additionally, the MTA MUST maintain the SNMP Interface for management and also the SNMP Key management interface. Also, the MTA MUST NOT continue Kerberized key management with CMSes until this object is set to 'true'. Note: MTAs MUST renew the CMS Kerberos tickets according to the PacketCable Security or IPCablecom Specification. If a value is written into an instance of pktcMtaDevEnabled, the agent MUST NOT retain the supplied value across MTA re-initializations or reboots.
