recover
Configures line-timing so the SPIO recovers timing from a port on an optical (OLC/OLC2) or channelized (CLC/CLC2)
card. The recovered clock is then distributed to synchronize timing on all line cards in the chassis.
card. The recovered clock is then distributed to synchronize timing on all line cards in the chassis.
Important:
To employ line-timing recovery, the SPIO card(s) must be equipped with the optional Stratum 3
clock module.

Entering the above command sequence results in the following prompt:
[local]host_name(config-port-slot_number/port_number)#
Syntax
recover { line1 slot# | line2 slot # }
no recover { line1 | line2 }
no
Deletes the identified line-timing source definition from the configuration.
line1 slot#
Sets first priority for line-timing clock recovered from the line card in the specified slot.
slot#:
a number between 1 and 48.
line2 slot#
Sets second priority for line-timing clock recovered from the line card in the specified slot.
slot#:
a number between 1 and 48. This cannot be the same slot number entered for
line1
.
Usage
Define which line-timing source has priority.
Important:
If the SPIO is connected to an external Building Integrated Timing Supply (BITS) source, BITS
timing always takes precedence over line-timing.
Example
Configure the line card in slot 19 as the preferred source for line-timing.
