2.6.96 INC-ISD
• Not Alarmed (NA), Non-Service Affecting (NSA)
The DS-3 Idle (INC-ISD) condition indicates that the XTC-28-3 card is receiving an idle signal, meaning
that the payload of the signal contains a repeating pattern of bits. The INC-ISD condition occurs when
the transmitting port has an OO-MT state. It is resolved when the OOS state ends.
Note INC-ISD is a condition and not an alarm. It is for information only and does not require troubleshooting.
2.6.97 INHSWPR
• Not Alarmed (NA), Non-Service Affecting (NSA)
The Inhibit Switch To Protect Request on Equipment (INHSWPR) condition occurs on traffic cards
when the ability to switch to protect has been disabled. If the card is part of a 1+1 protection scheme,
traffic remains locked onto the working system.
Procedure: Clear the INHSWPR Condition
Step 1 Complete the “Clear an External Switching Command” procedure on page 2-128.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC
(1-800-553-2447).

traffic remains locked onto the protect system.
