Using SNMP Traps
The Total Control Enterprise Network Hub provides for the management
of the Dual T1/PRI NAC via the Network Management Card (NC) NAC.
The NMC manages the Dual T1/PRI and other cards in the chassis using
Simple Network Management Protocol (SNMP).
One function of SNMP is to allow for faults, or traps, to be triggered
when one of the cards experiences an alarm condition. View the alarm
conditions using a standard MIB browser or 3Com’s Total Control
Manager/SNMP software.
The T1/PRI NAC triggers traps at both the card and span levels.
For a detailed listing and explanation of Dual T1/PRI traps, consult the
Total Control Parameter Reference on the Total Control CD-ROM or the
Total Control Manager/SNMP online help.
Signaling Channel
Down
N/A
Contact the Telco to see what their
side is receiving. If they’re showing
that the Signaling Channel is up,
there is most likely a problem in the
receiving pair at your site.
If the module is indicating alternating
Signaling Channel Up (Loopback LED
off) and signaling Channel Down
signals, there is most likely a cabling
mismatch between the TX and Rx
signals.
