Parameter Description
- HKT.
 [21] E1 QSIG = ECMA 143 QSIG over E1
 [22] E1 TNZ = ISDN PRI protocol for Telecom New Zealand
(similar to ETSI)
 [23] T1 QSIG = ECMA 143 QSIG over T1
 [30] E1 FRENCH VN6 ISDN = France Telecom VN6
 [31] E1 FRENCH VN3 ISDN = France Telecom VN3
 [34] T1 EURO ISDN =ISDN PRI protocol for Euro over T1
 [35] T1 DMS100 Meridian ISDN = ISDN PRI protocol for the
Nortel™ DMS Meridian switch
 [36] T1 NI1 ISDN = National ISDN 1 PRI protocol
 [40] E1 NI2 ISDN = National ISDN 2 PRI protocol over E1
 [50] BRI EURO ISDN = Euro ISDN over BRI
 [54] BRI QSIG = QSIG over BRI
 [55] BRI FRENCH VN6 ISDN = VN6 over BRI
 [56] BRI NTT = BRI ISDN Japan (Nippon Telegraph)
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 with E1 or T1 trunks.
[ProtocolType_x]
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.
[ISDNTimerT310]
Defines the T310 override timer for DMS, Euro ISDN, and ISDN
NI2 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.
[ISDNDMSTimerT310]
Overrides the 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 value 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).
[ISDNJapanNTTTimerT3JA]
Defines the T3_JA timer (in seconds). This parameter overrides the
internal PSTN T301 timeout on the Users Side (TE side).
