Abstract
A transmission device includes: a plurality of detectors configured to respectively detect alarms of a plurality of frame signals having divided client signals respectively; a memory configured to store group information indicating a group in which the client signal is in common regarding the plurality of frame signals; a specifying portion configured to specify, based on the group information, a second frame signal storing the client signal in common with a first frame signal in which a first alarm is detected by one of the plurality of detectors among the plurality of frame signals; and one or more generators configured to generate a second alarm for the second frame signal.

A transmission device comprising:
- a plurality of detectors configured to respectively detect alarms of a plurality of frame signals having divided client signals respectively;
- a memory configured to store group information indicating a group in which the client signal is in common regarding the plurality of frame signals;
- a specifying portion configured to specify, based on the group information, a second frame signal storing the client signal in common with a first frame signal in which a first alarm is detected by one of the plurality of detectors among the plurality of frame signals;
- and
- one or more generators configured to generate a second alarm for the second frame signal.
A method of controlling a transmission device, comprising:
- detecting, by a plurality of detectors, respectively alarms of a plurality of frame signals having divided client signals respectively;
- specifying a second frame signal to store the client signal in common with a first frame signal in which a first alarm is detected among the plurality of frame signals based on group information in a memory indicating a group in which the client signal is in common regarding the plurality of frame signals;
- and
- generating a second alarm for the second frame signal.
