12.12.6.2 TDM Bus and Clock Timing Parameters
The TDM Bus parameters are described in the table below.
Table 12-52: TDM Bus and Clock Timing Parameters
Parameter Description
TDM Bus Parameters
Web/EMS: PCM Law Select
[PCMLawSelect]
Determines the type of PCM companding law in input/output TDM
bus.
[1] Alaw = Alaw (default)
[3] MuLaw = MuLaw
Notes:
For this parameter to take effect, a device reset is required.
Typically, A-Law is used for E1 spans and Mu-Law for T1/J1
spans.
Web/EMS: 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]
Selects the clock source to which the device synchronizes.
[1] Internal = Generate clock from local source (default).
[4] Network = Recover clock from PSTN line.
For detailed information on configuring the device's clock settings,
see ''Clock Settings'' on page 637.
EMS/Web: TDM Bus Local
Reference
[TDMBusLocalReference]
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
