Version 6.8

[40] E1 NI2 ISDN = National ISDN 2 PRI protocol over E1

[50] BRI EURO ISDN = Euro ISDN over BRI

[51] BRI N12 ISDN

[52] BRI DMS 100 ISDN

[53] BRI 5ESS 10 ISDN

[54] BRI QSIG = QSIG over BRI

[55] BRI VN6 = VN6 over BRI

[56] BRI NTT = BRI ISDN Japan (Nippon Telegraph)

[57] BRI IUA
Notes:

All PRI trunks must be configured as the same line type (either
E1 or T1). The device can support different variants of CAS and
PRI protocols on different E1/T1 spans (no more than four
simultaneous PRI variants).

BRI trunks can operate together with E1 or T1 trunks.
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).
Notes:

For this 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 this parameter, it is recommended to use
the parameter ISDNTimerT310.

This 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 other value than
0, it overrides the timer with this value.
