SIP User's Manual

[0] Disable = Disabled (default).

[1] Enable = TDM Tunneling is enabled.
When TDM Tunneling is enabled, the originating device
automatically initiates SIP calls from all enabled B-channels
pertaining to E1/T1/J1 spans that are configured with the
'Transparent' protocol. The called number of each call is the
internal phone number of the B-channel from where the call
originates. The 'The Inbound IP Routing Table is used to define the
destination IP address of the terminating device. The terminating
device automatically answers these calls if its E1/T1 protocol is set
to 'Transparent' (ProtocolType = 5).
Notes:

For this parameter to take effect, a device reset is required.

For an overview on TDM tunneling, see ''TDM Tunneling'' on
page 222.
Table A-50: TDM Bus and Clock Timing Parameters
Determines the type of pulse-code modulation (PCM) companding
algorithm law in input and output TDM bus.

[1] Alaw = A-law

[3] MuLaw = Mu-Law
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.
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.
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.
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.
Determines the clock source to which the device synchronizes.

[1] Internal = Generate clock from local source (default).

[4] Network = Recover clock from PSTN line.
