This chapter presents information on how to monitor andinterpret the HotWire 7924 and 7925 nest card termination unit front panel LEDs.You can also monitor loop status, change operational parameters, or initiateloopback testing from the Maintenance Processor (HTU-M or HTU-S) Front Panelor from a VT100-compatible terminal connected to the HTU-M or HTU-S by usingthe Maintenance, Performance, or Status options from the Main Menu.The HTU-M and HTU-S maintenance processors: Monitor the status of up to 62 or 63 (HTU-S option only) nest card terminationunits Store the performance history of individual circuits and network status Monitor and display individual circuit and loop status on the maintenanceprocessor front panel Display individual circuit and loop status on the VT100-compatible terminal orPC running a VT100-compatible terminal emulator programThe HTU-S maintenance processor: Interfaces with and reports circuit status to your Network ManagementSystem using Simple Network Management Protocol (SNMP)For more information on the maintenance processor, refer to theHotWireModel 7900 Basic Maintenance Processor User’s Guide.
