Syntax
Sets the timer values to default duration for specific STC procedure in an ALCAP service.
Specifies the duration in millinseconds for STC long timer. This timer is used by the congestion indication
procedure. Receipt of a repeated congestion indication from MTP3B before the expiry of this timer is
interpreted as the congestion situation. On the other hand, if no congestion indication is received from
MTP3B before expiry of this timer, the congestion situation is considered to have improved.

must be an integer value from 5000 through 10000.
Default: 5000
Specifies the duration in millinseconds for STC short timer. This timer is used by the congestion indication
procedure. The role of this timer is to avoid overreacting if multiple congestion indications are received from
MTP3B in quick succession.

must be an integer value from 300 through 600.
Default: 300
Usage
Use this command to configure the long (T30) and short (T29) timer for congestion indication procedure in
ALCAP service.
When the first congestion indication is received by, the traffic load into the affected destination point code is
reduced and the same time two timers STC short timer (T29) and STC long timer (T30) are started. During
STC short timer all received congestion indications for the same destination point code are ignored in order
not to reduce traffic too rapidly. Reception of a congestion indication after the expiry of STC short timer, but
still during STC long timer, will decrease the traffic load by one more step and restart both the timers again.
If STC long timer expires (i.e. no congestion indications having been received during the STC long timer
period), traffic will be increased by one step and STC long timer will be restarted unless full traffic load has
been resumed.
