Introduction and Specifications
Management Features
The SpectraComm Manager card provides craft, Telnet, and LAN connections for SRM-6
communication, monitoring, and management functions. These functions are accessed via the SCM
front panel EIA-232 craft (CTRL) port, the rear panel DB25F LAN port, and the rear panel RJ45
WAN/DBU WAN ports.
Discovery via the SCM
The SCM card performs network discovery of the SRM-6. The discovery function identifies
compatible network elements located in the SpectraComm shelf and stores element information in
its local database. Information includes the element type, configuration checksum, serial number,
alarm status, and equipment status. The user can access this information by means of the SCM
Management Information Base (MIB).
Alarms and Traps
After the initial Discovery, the SCM card polls the active slot addresses for alarms and statistical
data on network elements and also polls one inactive slot. By reducing the frequency at which it
polls inactive slots, the SCM card can continuously monitor as rapidly as possible and still discover
newly installed SCM-compatible equipment. The SCM communicates continually with the
SRM-6 and forwards its alarm traps to a designated controller.
Note
Refer to the SCM Installation and Operation Manual for additional information on the communication,
discovery, trap forwarding, and management functions provided for the SRM-6.
Diagnostics
SRM-6 provides an aggregate loopback diagnostic test that can be initiated at the SCM craft port or
via a Telnet connection. This test loops aggregate Transmit Data from the DTEs to Receive Data to
the DTEs.
Maintenance
Maintenance features include menu-driven commands for Soft Reset, Load Factory Defaults, and
Firmware Download.
Alarms
SRM-6 Channel Alarms (one for each channel) include No RTS and No Remote CTS.
SRM-6 Aggregate Alarms include No DCD, No Frame Sync, and No Remote Frame Sync.
