Signaling Channel | N/A | ■ Contact the Telco to see what their |
Down |
| 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. |

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
Total Control Manager/SNMP online help.
