| System Log - The System Log records all system activity and is maintained in non-volatile memory in the
EMS platform. Included in the System Log are faults, alarms, configuration commands, provisioning requests, and call activity. The level of detail within each area is configurable by the System Administrator. The EMS also provides facilities for interrogating the System Log to select and display events in a straightforward manner. This includes facilities such as analysis of faults, reports on call activity for the system of a select group of lines, examinations of commands invoked by a particular operator, etc. Subscriber Call Data - The EMS maintains subscriber call information similar to that used in typical Call Detail Record (CDR) accounting. This information includes caller ID, called party ID, call origination and termination times, call priority, and other lower level information used in calculating system performance statistics. AirLink 8000 1/30/00 BASE TRANSCEIVER STATION Release 1.00 2 - 18 1.9 MAINTENANCE Test and Diagnostics - The Test and Diagnostics functions are contained within the Built-In-Test (BIT) capabilities of the system. Inherent hardware and software tests exist within the AirLink 8000 equipment down to the level of a Field Replaceable Unit (FRU) and are designed to detect and isolate non-functional FRUs as rapidly as possible. At a minimum, the internal hardware tests for each FRU are able to indicate the operational status at power-on and upon request from the monitoring unit. More detailed software tests reside both internally and externally to the various FRUs and are used to further evaluate their operational status. Application of BIT is dependent on the current state or mode of the FRU(s). The three state conditions are defined as follows: tải về 0.71 Mb. Chia sẻ với bạn bè của bạn:
