Very whetherTCD and CTI Manager service are running. The CcmLineLinkState performance monitor for the attendant console provides a quick way to check whether the attendant console is functioning correctly: If the CcmLineLinkState counter is 11, this state indicates that Cisco TCD is functioning normally. The left-most digit of CcmLineLinkState indicates whether Cisco TCD is connected to and registered with the Cisco CallManager CTI. If this digit is 0, a problem may exist with the CTI or the directory. The right-most digit of CcmLineLinkState indicates whether Cisco TCD can perceive line state information through Cisco CallManager. If this digit is 0, a problem probably exists with Cisco CallManager.

Note When an attendant console user cannot log in to the attendant console and no line state information is available, view the CcmLineLinkState performance monitor to verify that all components of attendant console are functioning properly. Make sure you have the Cisco Telephony Call Dispatcher started on the pub and all subs.
