Parameter Description
Web: TDM Bus Fallback Clock
Source
EMS: TDM Bus Fallback Clock
[TDMBusFallbackClock]
Determines the fallback clock source on which the device
synchronizes in the event of a clock failure.
 [4] Network (default)
 [8] H.110_A
 [9] H.110_B
 [10] NetReference1
 [11] NetReference2
Web/EMS: TDM Bus Net
Reference Speed
[TDMBusNetrefSpeed]
Defines the NetRef frequency (for both generation and
synchronization).
 [0] 8 kHz (default)
 [1] 1.544 MHz
 [2] 2.048 MHz
Web: TDM Bus PSTN Auto
FallBack Clock
EMS: TDM Bus Auto Fall Back
Enable
[TDMBusPSTNAutoClockEna
ble]
Enables the PSTN trunk Auto-Fallback Clock feature.
 [0] Disable (default) = Recovers the clock from the E1/T1 line
defined by the parameter TDMBusLocalReference.
 [1] Enable = Recovers the clock from any connected
synchronized slave E1/T1 line. If this trunk loses its
synchronization, the device attempts to recover the clock from
the next trunk. Note that initially, the device attempts to recover
the clock from the trunk defined by the parameter
TDMBusLocalReference.
Notes:
 For this parameter to take effect, a device reset is required.
 This parameter is relevant only if the parameter
TDMBusClockSource is set to 4.
Web: TDM Bus PSTN Auto
Clock Reverting
EMS: TDM Bus Auto Fall Back
Reverting Enable
[TDMBusPSTNAutoClockRev
ertingEnable]
Enables the PSTN trunk Auto-Fallback Reverting 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
Notes:
 For this parameter to take effect, a device reset is required.
 This parameter is applicable only when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
Web: Auto Clock Trunk Priority
EMS: Auto Trunk Priority
[AutoClockTrunkPriority]
Defines the trunk priority for auto-clock fallback (per trunk
parameter).
 0 to 99 = priority, where 0 (default) is the highest.
 100 = the SW never performs a fallback to that trunk (usually
used to mark untrusted source of clock).
Note: Fallback is enabled when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
