Mediant 500 MSBR
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).
Note:

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.
[ISDNDMSTimerT310] 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).
Note:

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).
[ISDNTimerT301] 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.
Note:

For the parameter to take effect, a device reset is required.

The parameter is applicable only to the QSIG variant.
[ISDNJapanNTTTimerT3JA] 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 value is -1 to 300. The default is 0 (meaning 50 sec).
The value -1 means that no timer is activated.
Note:

This timer is also affected by the parameter
PSTNAlertTimeout.

The parameter is applicable only to the Japan NTT PRI variant
(ProtocolType = 16).
Trace Level

[TraceLevel]
Defines the trace level:

[0] No Trace (default)

[1] Full ISDN Trace

[2] Layer 3 ISDN Trace

[3] Only ISDN Q.931 Messages Trace

[4] Layer 3 ISDN No Duplication Trace
Framing Method
configure voip > interface e1-t1
Determines the physical framing method for the trunk.

[0] Extended Super Frame = (Default) Depends on protocol
