User's Manual
feature. If enabled and a trunk returning to service has
an AutoClockTrunkPriority parameter value that is
higher than the priority of the local reference trunk (set in
the TDMBusLocalReference parameter), the local
reference reverts to the trunk with the higher priority that
has returned to service for the device's clock source.

[0] Disable (default)

[1] Enable
Note:

For the parameter to take effect, a device reset is
required.

The parameter is applicable only when the
TDMBusPSTNAutoClockEnable parameter is set to
1.
Defines the trunk priority for auto-clock fallback (per
trunk parameter).
The valid range is 0 to 100, where 0 (default) is the
highest priority and 100 indicates that the device does
not perform a fallback to the trunk (typically, used to
mark untrusted source of clock).
Note: Fallback is enabled when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
Table 69-58: ISDN Parameters
Determines the ISDN termination side.

[0] User side = (Default) ISDN User Termination Equipment
(TE) side.

[1] Network side = ISDN Network Termination (NT) side.
Note: Select 'User side' when the PSTN or PBX side is
configured as 'Network side' and vice versa. If you don't know
the device's ISDN termination side, choose 'User side'. If the
D-channel alarm is indicated, choose 'Network Side'.
The BRI module supports the ITU-T I.430 standard, which
defines the ISDN-BRI layer 1 specification. When an NT port is
active, it drives a 38-V line and sends an INFO1 signal (as
defined in ITU-T I.430 Table 4) on the data line to synchronize
to a TE port that might be connected to it. To stop the voltage
and the INFO1 signal on the line, stop the trunk using the Stop
Trunk button.
Same as the description for parameter TerminationSide, but
for a specific trunk ID (where x denotes the Trunk ID and 0 is
the first Trunk).
Enables the device to ignore ISDN Disconnect messages with
PI 1 or 8.
