Abstract:
1. A method, performed by a device, the method comprising: receiving, at a processor of the device, a low line rate data frame including an overhead byte, where the low line rate data frame includes a synchronous optical network (SONET) data frame and where the overhead byte includes a byte within a path overhead (POH) of the data frame; determining, by the processor, whether a value associated with the overhead byte indicates that a transmitting device operating mode matches a receiving device operating mode, where the overhead byte further indicates whether the low line rate data frame should be reassembled with other low line rate data frames to form a high line rate data frame; generating, by the processor, an alarm when it is determined that the value associated with the overhead byte indicates that the transmitting device operating mode does not match the receiving device operating mode; and sending, by the processor, the alarm to the transmitting device.
