67.10.6.2 TDM Bus and Clock Timing Parameters
The TDM Bus parameters are described in the table below.
Table 67-56: TDM Bus and Clock Timing Parameters
Parameter Description
TDM Bus Parameters
Web/EMS: PCM Law Select
[PCMLawSelect]
Determines the type of pulse-code modulation (PCM)
companding algorithm law in input and output TDM bus.
 [1] Alaw
 [3] MuLaw
The default value is automatically selected according to the
Protocol Type of the selected trunk. If the Protocol Type is set to
NONE, the default is MuLaw.
Notes:
 For this parameter to take effect, a device reset is required.
 Typically, BRI is used for most BRI variants.
Web/EMS: Idle PCM Pattern
CLI: idle-pcm-pattern
[IdlePCMPattern]
Defines the PCM Pattern that is applied to the E1/T1 timeslot
(B-channel) when the channel is idle.
The range is 0 to 255. The default is set internally according to
the Law select 1 (0xFF for Mu-Law; 0x55 for A-law).
Note: For this parameter to take effect, a device reset is
required.
Web/EMS: Idle ABCD Pattern
[IdleABCDPattern]
Defines the ABCD (CAS) Pattern that is applied to the CAS
signaling bus when the channel is idle.
The valid range is 0x0 to 0xF. The default is -1 (i.e., default
pattern is 0000).
Notes:
 For this parameter to take effect, a device reset is required.

This parameter is applicable only when using PSTN interface
with CAS protocols.
Web/EMS: 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 this parameter to take effect, a device reset is
required.
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
