65.10.6.2 TDM Bus and Clock Timing Parameters
The TDM Bus parameters are described in the table below.
Table 65-57: TDM Bus and Clock Timing Parameters
Parameter Description
TDM Bus Parameters
PCM Law Select
configure voip > media tdm > 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. E1 defaults to
ALaw; T1 defaults to MuLaw. If the Protocol Type is set
to NONE, the default is MuLaw.
Note:
 For the parameter to take effect, a device reset is
required.
 Typically, A-Law is used for E1 spans; Mu-Law for
T1/J1 spans.
 Typically, A-Law is used for most BRI variants.
Idle PCM Pattern
configure voip > media tdm > idle-pcm-
pattern
[IdlePCMPattern]
Defines the PCM Pattern that is applied to the PSTN
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 the parameter to take effect, a device reset is
