timers.t_t2_dur
t_t2_durt_t2_dur
t_t2_dur
Q.703 T2 timer. Total time, in milliseconds, that the L2 attempts link
alignment. If the link has still not aligned by this time, the link activation is
failed.
timers.t_t3_dur
t_t3_durt_t3_dur
t_t3_dur
Q.703 T3 timer. Total time, in milliseconds, that the L2 remains aligned
before starting proving while waiting for the remote L2 to also become
aligned. If the remote L2 does not become aligned by this time, the link
activation is failed.
timers.t_t4n_dur
t_t4n_durt_t4n_dur
t_t4n_dur
Q.703 T4 timer for normal proving. Total time, in milliseconds, for the
proving period.
timers.t_t4e_dur
t_t4e_durt_t4e_dur
t_t4e_dur
Q.703 T4 timer for emergency proving. Total time, in milliseconds, for the
proving period.
timers.t_t5_dur
t_t5_durt_t5_dur
t_t5_dur
Q.703 T5 timer. Total time, in milliseconds, between sending successive
SIB signal units to the remote L2 when this L2 is suffering from receiving
congestion.
timers.t_t6_dur
t_t6_durt_t6_dur
t_t6_dur
Q.703 T6 timer. Maximum time, in milliseconds, for which a remote L2
can refuse to accept message signal units due to congestion before the
L2 declares the link failed.
timers.t_t7_dur
t_t7_durt_t7_dur
t_t7_dur
Q.703 T7 timer. Maximum time, in milliseconds, between new MSU
acknowledgments from the remote L2. In periods of receive congestion, it
becomes the maximum time between reception of SIB signal units while a
remote L2 is refusing to accept message signal units due to congestion
before the L2 declares the link failed.
rcv_congestion
rcv_congestionrcv_congestion
rcv_congestion MTP2 receive congestion parameters.
rcv_congestion.onset
onsetonset
onset
Receive congestion onset threshold. If the number of MSUs in the
reception buffer gets bigger than this value, level 2 flow control measures
begin.
rcv_congestion.abate
abateabate
abate
Receive congestion abatement threshold. If the number of MSUs in the
reception buffer falls below this value, level 2 flow control measures end
(if in operation).
