ProtocolType_x:

[0] NONE

[50] BRI EURO ISDN = Euro ISDN over BRI

[51] BRI NI2 ISDN

[52] BRI DMS 100 ISDN

Defines the protocol type for a specific trunk ID (where x denotes
the Trunk ID and 0 is the first trunk). For more information, see the
ProtocolType parameter.
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).
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.
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).
Defines the override T301 timer (in seconds). The T301 timer is
