Parameter Description
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.
The ISDN BRI North American variants (NI-2, DMS-100, and
5ESS) are partially supported by the device. Please contact
your AudioCodes sales representative before implementing
this protocol.
[ProtocolType_x] Defines the protocol type for a specific trunk ID (where x denotes
the Trunk ID and 0 is the first trunk). Fo
r more information, see the
ProtocolType parameter.
[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 reset 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 reset is required.
The parameter is applicable only to the QSIG variant.
[ISDNJapanNTTTimerT3JA] Defines the T3_JA timer (in seconds). The parameter overrides
the internal PSTN T301 timeout on the Users Side (TE side). If an
outgoing call from the device to ISDN is not answered during this
timeout, the call is released.
The valid value is -1 to 300. The default is 0 (meaning 50 sec).
The value -1 means that no timer is activated.
