This object is used to configure the time interval for which the periodic timer needs to be restarted, when the corresponding main ring indicates the virtual channel status change to this sub-ring and when the virtual channel of this sub-ring is in failed state. When one of the ring port of the main ring is in failed state, main ring indicates virtual channel status change indication to sub-ring when one of the following event happens: - R-APS (NR) is received on a ring port of the main ring - Local Clear SF on the main ring. On getting this virtual channel status indication from the main ring, this sub-ring will restart the periodic timer for this value, only if the virtual channel is in failed state. Once the periodic timer expires, it will get restarted only for the normal periodic time (value present in fsErpsRingConfigPeriodicTime). This object is valid only for sub-rings. For normal rings, configuring this object will not have any impact. This value must be configured on both the inter-connected nodes of the main ring. It is recommended to configure the value for this object as: (Periodic Timer Value + 3 * CC interval + GuardTimer Value of Main Ring + delta-T). It is recommended to have 3*CC interval as delta-T. The configured value of this timer is applicable only from the next start/re-start of the timer. This object can take the value between 0 to 1 hour, configurable in unit of 1 milliseconds. For example, to configure the value as 5 seconds, configure the value as 5000. Default value for this object is 5560. This value is derived from the above formula with periodic timer value as 5 seconds, CC interval as 10 milliseconds, guard timer value as 500 milliseconds and delta T as 30 milliseconds.
