SIP User's Manual
Enables TDM tunneling.

[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 '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 431.
Determines the type of PCM companding law in input/output
TDM bus.

[1] Alaw = Alaw (default)

[3] MuLaw = 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.
