Parameter Description

[4] Network = Recover clock from PSTN line.
Web/EMS: TDM Bus Local
Reference
[TDMBusLocalReference]
Defines the physical Trunk ID from which the device recovers
(receives) its clock synchronization.
The range is 0 to the maximum number of Trunks. The default is
0.
Note: This parameter is applicable only if the parameter
TDMBusClockSource is set to 4 and the parameter
TDMBusPSTNAutoClockEnable is set to 0.
Web/EMS: TDM Bus Enable
Fallback
[TDMBusEnableFallback]
Defines the automatic fallback of the clock.
 [0] Manual (default)
 [1] Auto Non-Revertive
 [2] Auto Revertive
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 Master-
Slave Selection
[TDMBusMasterSlaveSelecti
on]
Defines the SC/MVIP/H.100/H.110.
 [0] SlaveMode = (Default) Slave mode (another device must
supply the clock to the TDM bus) or Master mode (the device
is the clock source for the TDM bus) or Secondary Master
mode (for H100/H110 Bus only).
 [1] MasterMode = H110A Master in Master mode.
 [2] SecondaryMasterMode = H.110B Master.
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
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
