[ISDNTimerT310]
|
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 restart 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 restart is required. |
|
■
|
The parameter is applicable only to the ISDN QSIG protocol variant and the Network side of the NTT ISDN protocol variant. |
|
■
|
This timer is also affected by the [PSTNAlertTimeout] parameter. |
|
|
[TrunkLifeLineType]
|
Defines the scenarios upon which the device activates PSTN Fallback for digital interfaces. When PSTN Fallback is triggered, the device automatically routes incoming Tel calls to the PSTN (instead of to the IP).
|
■
|
[0] = (Default) PSTN Fallback is activated upon the loss of power to the device, for example, due to a power outage or the unplugging of the device's power cable. |
PSTN Fallback is provided by two ports, where one port is connected to the PBX, for example, and the other to the PSTN. When PSTN Fallback is triggered, for example, due to a power outage, the device automatically connects the two ports using a metallic relay switch. In such a scenario, calls originating from the PBX are routed directly to the PSTN (instead of the IP network). For more information on PSTN Fallback cabling, refer to the Hardware Installation Manual.
Note:
|
■
|
For the parameter to take effect, a device restart is required. |
|
■
|
The parameter is applicable only to the digital interfaces. |
|
■
|
PSTN Fallback is supported only on specific hardware configurations and where dual digital ports are provided. For more information, refer to the Hardware Installation Manual. |
|
■
|
The PSTN Fallback feature has no relation to the PSTN Fallback License Key.
|
|
|
[AdminState]
|
Defines the administrative state for all trunks.
|
■
|
[0] = Lock the trunk; stops trunk traffic to configure the trunk protocol type. |
|
■
|
[1] = Shutting down (read only). |
|
■
|
[2] = (Default) Unlock the trunk; enables trunk traffic. |
Note:
|
■
|
For the parameter to take effect, a device restart is required. |
|
■
|
When the device is locked from the Web interface, the parameter changes to 0. |
|
■
|
To define the administrative state per trunk, use the [TrunkAdministrativeState] parameter. |
|
|
[TrunkAdministrativeState_x]
|
Defines the administrative state per trunk, where x denotes the trunk number.
|
■
|
[0] = Lock the trunk; stops trunk traffic to configure the trunk protocol type. |
|
■
|
[1] = shutting down (read only). |
|
■
|
[2] = (Default) Unlock the trunk; enables trunk traffic. |

[ISO8859CharacterSet]
|
Defines the ISO 8859 character set type (languages) for representing the alphanumeric string of the calling name (caller ID) in the forwarded message, for IP-to-Tel and Tel-to-IP calls.
|
■
|
[0] = No Accented - proprietary method where incoming INVITE messages with any accented characters (e.g., á, é, í, ó, and ü), which are represented in a 2-byte unicode character, are translated to Latin-only, which are normal one-byte ASCII characters (a, e, i, o, and u, respectively). |
|
■
|
[1] = Western European (Default) |
