Remote Alarm Method
Two methods may be used to indicate to the end equipment of an alarm condition following
loss of synchronization:
• Bit 3 of TS (Time Slot) 0: Under normal conditions, this bit is always set to 0. Upon
identification of an alarm condition, it is set to 1.
• Unframed all ones: The transmitted signal comprises a continuous sequence of ones
without any ramming or other signalling messages The Remote alarm method should
be set in accordance with the configuration of the end equipment.
