Table 5-45: TDM Bus Settings Parameters

[1] Alaw = Alaw (default)
[3] MuLaw = MuLaw
Usually A-Law is used for E1 spans and µ-Law for T1 and J1
spans.
N/A.
Defines the PCM Pattern that is applied to 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).
ABCD (CAS) Pattern to be applied to CAS signaling bus when the
channel is idle.
Range 0x0 to 0xF. Default is -1 (default pattern = 0000).
Note: This is only relevant when using PSTN interface with CAS
protocols.
0 to 3 (default = 0).
Physical Trunk ID from which the gateway recovers its clock.
Note: Applicable only if TDMBusClockSource = 4 and
TDMBusPSTNAutoClockEnable = 0.
Enables or disables the PSTN trunk auto-fallback clock feature.
[0] Disable = Recovers the clock from the E1/T1 line defined
by the parameter TDMBusLocalReference (default).
[1] Enable = 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.
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 gateway
LocalReference changes to the new trunk.
[0] Disable (default)
[1] Enable
Note: The parameter is valid only when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
[1] Internal = Generate clock from local source (default).
[4] Network = Recover clock from PSTN line.
For detailed information on configuring the gateway's clock
settings, refer to 'Clock Settings' on page 439.
