2.7.416 TIM-S
Clear the TIM-P Alarm
Step 1 Complete the “Clear the TIM Alarm” procedure on page 2-244. (The option will say “Edit J1 Path Trace”
rather than “Edit J0 Path Trace.”)
Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447. If the alarm applies to the STSTRM object, it
is Service-Affecting (SA).
2.7.416 TIM-S
Default Severity: Critical (CR), Service-Affecting (SA)
SONET Logical Objects: EC1, OCN
The TIM for Section Overhead alarm occurs when there is a mismatch between the expected and
received J0 section overhead strings in either Manual or Auto mode.
In manual mode at the DS3/EC1-48 card Section Trace window, the user enters the expected string into
the Current Expected String field for the receiving port. The string must match the string typed into the
Transmit String field for the sending port. If these fields do not match, the login node raises the TIM-S
alarm.
In Auto mode on the receiving port, the card sets the expected string to the value of the received string.
If the alarm occurs on a port that has been operating with no alarms, the circuit path has changed or
someone entered a new incorrect value into the Current Transmit String field. Complete the following
procedure to clear either problem.
TIM-S also occurs on a port that has previously been operating without alarms if someone switches the
cables or optical fibers that connect the ports. If TIM-S is enabled on the port, the “AIS-L” alarm on
page 2-37 can be raised downstream and the “RFI-L” alarm on page 2-204 can be raised upstream.
Note AIS-L and RFI-L are disabled or enabled in the Provisioning > EC1 > Section Trace tab Disable
AIS/RDI on TIM-S? check box.
Clear the TIM-S Alarm
Step 1 Double-click the DS3/EC1-48 card to open the card view.
Step 2 Click the Provisioning > EC1 > Section Trace tabs.
Step 3 Choose the port from the Port pull-down.
Step 4 In the Expected area, enter the correct string into the Current Expected String field.
Step 5 Click Apply.
Step 6 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC 1 800 553-2447. If the alarm applies to the STSTRM object, it
is Service-Affecting (SA).
