Table 5-33: TDM Bus Settings Parameters (continues on pages 157 to 158)
Parameter Description
Idle ABCD Pattern
[IdleABCDPattern]
ABCD (CAS) Pattern to be applied to CAS signaling bus when the
channel is idle.
Range 0x0 to 0xF
Default = -1 (default, pattern = 0000)
Note: This is only relevant when using PSTN interface with CAS
protocols.
TDM Bus Local Reference
[TDMBusLocalReference]
0 to 4 (default = 0)
Physical Trunk ID from which the gateway recovers its clock.
Note: Applicable only if TDMBusClockSource = 4 and
TDMBusPSTNAutoClockEnable = 0.
TDM Bus PSTN Auto Clock
[TDMBusPSTNAutoClockEnable]
0 = Recovers the clock from the E1/T1 line defined by the
parameter TDMBusLocalReference (default)
1 = Recovers the clock from any connected synchronized slave
E1/T1 line. If this trunk loses its synchronization, the gateway
attempts to recover the clock from the next trunk. Note that initially
the gateway attempts to recover the clock from the trunk defined
by the parameter TDMBusLocalReference.
Note: This parameter is relevant only if TDMBusClockSource = 4.
TDM Bus PSTN Auto Clock Reverting
[TDMBusPSTNAutoClockRevertingEnabl
e]
Enables or disables the PSTN trunk auto-fallback reverting
feature. If a trunk with a higher priority than the current
LocalReference is being synchronized, the board LocalReference
changes to the new trunk.
Valid options include:
0 = Disable (default)
1 = Enable
Note: The parameter is valid only when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
TDM Bus Clock Source
[TDMBusClockSource]
1 = Generate clock from local source (default).
4 = Recover clock from PSTN line.
For detailed information on configuring the gateway’s clock
settings, refer to Section
10.1 on page 293.
