SIP User's Manual
Determines the type of PCM companding law in input/output TDM
bus.
[1] Alaw = Alaw (default)
[3] MuLaw = MuLaw
Note: Typically, A-Law is used for E1 spans and µ-Law for T1/J1
spans.
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).
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 =
0000).
Note: This parameter is applicable only when using PSTN interface
with CAS protocols.
Physical Trunk ID from which the device recovers (receives) its
clock synchronization.
The range is 0 to maximum number of Trunks. The default is Trunk
ID 1.
Note: This parameter is applicable only if the parameter
TDMBusClockSource is set to 4 and the parameter
TDMBusPSTNAutoClockEnable is set to 0.
Enables or disables the PSTN trunk auto-fallback clock feature.
[0] Disable (default) = Recovers the clock from the E1/T1 line
defined by the parameter TDMBusLocalReference.
[1] Enable = Recovers the clock from any connected
synchronized slave E1/T1 line. If this trunk loses its
synchronization, the device attempts to recover the clock from
the next trunk. Note that initially, the device attempts to recover
the clock from the trunk defined by the parameter
TDMBusLocalReference.
Note: This parameter is relevant only if the parameter
TDMBusClockSource is set to 4.
