  [20] T1 HKT ISDN = ISDN PRI protocol for the Hong Kong - 
HKT. 
  [21] E1 QSIG = ECMA 143 QSIG over E1 
  [22] E1 TNZ = ISDN PRI protocol for Telecom New Zealand 
(similar to ETSI)

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

Note: For supported protocols, please contact your AudioCodes 
representative. 
[ProtocolType_x] 
Same as the description for the parameter ProtocolType, but for a 
specific trunk ID (where x denotes the Trunk ID and 0 is the first 
trunk).  
[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).
