IDU Service Restoration Times
3DB 23063 ADAA - Rev 004 July 2007
Service restoration times for a transmit or receive switch are:
IDU Transmit Switch:
• Within 200ms for a local alarm Tx switch.
• Within 20 seconds nominally for a silent Tx switch.
IDU Receive Switch:
• Rx switching is hitless (errorless) for all events except for an online Rx switch.
• For an online Rx switch, service restoration is within 200 ms. (The online Rx
controls the hitless protection mechanism - the protection switch. When the
protection switch function is changed from one IDU to its partner, the switching
is not hitless).
