Version 7.2 1221 Mediant 800B Gateway & E-SBC
User's Manual 72. Configuration Parameters Reference
Parameter Description
[PCMLawSelect]

[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
required.
Idle ABCD Pattern
configure voip > media tdm > 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).
Note:
 For the parameter to take effect, a device reset is
required.
 The parameter is applicable only when using PSTN
interface with PRI CAS protocols.
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
