MTP2 Timers
A total of 6 timers can be set as part of the common link configuration process. They are as follows (with definitions):
T1 Timer
Alignment ready timer (the same as TTC JT-Q.703 remote verification in progress timer). Typical value is 40000 milliseconds (40 seconds) for ITU and 13000 milliseconds (13 seconds) for ANSI.
T2 Timer
Not aligned timer (the same as TTC JT-Q.703 wait for remote startup in progress timer). Typical value is 5000 milliseconds (5 seconds) for ITU and 11800 milliseconds (11.8 seconds) for ANSI.
T3 Timer
Aligned timer (the same as TTC JT-Q.703 initialization in progress timer). Typical value is 1500 milliseconds (1.5 seconds) for ITU and 11800 milliseconds (11.8 seconds) for ANSI.
T5 Timer
Sending SIB timer. Typical value is 100 milliseconds (0.1 second).
T6 Timer
Remote congestion timer. Typical value is 3000 milliseconds (3 seconds).
T7 Timer
Excessive delay of acknowledgment timer. Typical value is 1000 milliseconds (1 second).
NOTE: For all timers, a value of '0' is not permitted. Also, please note that there is no T4 Timer.
