2.7.171 INC-ISD
The DS-3 Idle condition indicates that the DS-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 OOS-MA,MT service state. It is resolved when the OOS-MA,MT state ends.
INC-ISD is a condition and not an alarm. It is for information only and does not require troubleshooting.
