User's Manual
Defines the T310 override timer for DMS, Euro ISDN, and ISDN NI-
2 variants. An ISDN timer is started when a Q.931 Call Proceeding
message is received. The timer is stopped when a Q.931 Alerting,
Connect, or Disconnect message is received from the other end. If
no ISDN Alerting, Progress, or Connect message is received within
the duration of T310 timer, the call clears.
The valid value range is 0 to 600 seconds. The default is 0 (i.e.,
use the default timer value according to the protocol's
specifications).
Notes:

For the parameter to take effect, a device reset is required.

When both the parameters ISDNDmsTimerT310 and
ISDNTimerT310 are configured, the value of the parameter
ISDNTimerT310 prevails.
Defines the override T310 timer for the DMS-100 ISDN variant.
T310 defines the timeout between the receipt of a Proceeding
message and the receipt of an Alerting/Connect message.
The valid range is 10 to 30. The default is 10 (seconds).
Notes:

Instead of configuring the parameter, it is recommended to use
the parameter ISDNTimerT310.

The parameter is applicable only to Nortel DMS and Nortel
MERIDIAN PRI variants (ProtocolType = 14 and 35).
Defines the override T301 timer (in seconds). The T301 timer is
started when a Q.931 Alert message is received. The timer is
stopped when a Q.931 Connect/Disconnect message is received
from the other side. If no Connect or Disconnect message is
received within the duration of T301, the call is cleared.
The valid range is 0 to 2400. The default is 0 (i.e., the default T301
timer value - 180 seconds - is used). If set to any value other than
0, it overrides the timer with this value.
Notes:

For the parameter to take effect, a device reset is required.

The parameter is applicable only to the QSIG variant.
Defines the T3_JA timer (in seconds). The parameter overrides the
internal PSTN T301 timeout on the Users Side (TE side).
If an outgoing call from the device to ISDN is not answered during
this timeout, the call is released.
The valid range is 10 to 240. The default is 50.
Notes:

This timer is also affected by the parameter PSTNAlertTimeout.

The parameter is applicable only to the Japan NTT PRI variant
(ProtocolType = 16).
