User's Manual 69. Configuration Parameters Reference
Parameter Description
TDM Bus Clock Source
[TDMBusClockSource]
Defines the clock source to which the device
synchronizes.
 [1] Internal = (Default) Generate clock from local
source.
 [4] Network = Recover clock from PSTN line.
Note:
 For the parameter to take effect, a device reset is
required.
TDM Bus Local Reference
configure voip > media tdm > 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: The parameter is applicable only if the parameter
TDMBusClockSource is set to 4 and the parameter
TDMBusPSTNAutoClockEnable is set to 0.
TDM Bus Enable Fallback
[TDMBusEnableFallback]
Defines the automatic fallback of the clock.
 [0] Manual (default)
 [1] Auto Non-Revertive
 [2] Auto Revertive
TDM Bus Fallback Clock Source
[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
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
TDM Bus PSTN Auto FallBack Clock
configure voip > media tdm > pstn-bus-
auto-clock
[TDMBusPSTNAutoClockEnable]
Enables the PSTN trunk Auto-Fallback Clock feature.
 [0] Disable = (Default) Recovers the clock from the
trunk line defined by the parameter
TDMBusLocalReference.
 [1] Enable = Recovers the clock from any connected
synchronized slave trunk 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.
Note:
 For the parameter to take effect, a device reset is
required.
 The parameter is applicable only if the
TDMBusClockSource parameter is set to 4.
TDM Bus PSTN Auto Clock Reverting Enables the PSTN trunk Auto-Fallback Reverting
