SIP User's Manual
Same as the description for parameter ClockMaster, but for a
specific Trunk ID (where x denotes the Trunk ID and 0 is the first
Trunk).
Selects B8ZS or AMI for T1 spans, and HDB3 or AMI for E1 spans.

[0] B8ZS = use B8ZS line code (for T1 trunks only) default.

[1] AMI = use AMI line code.

[2] HDB3 = use HDB3 line code (for E1 trunks only).
Same as the description for parameter LineCode, but for a specific
trunk ID (where 0 depicts the first trunk).
Defines the administrative state of a trunk.


[0] 0 dB (default)

[1] -7.5 dB


Note: This parameter is not applicable for PRI E1 trunks.
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 'IP to Trunk Group' 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, refer to TDM Tunneling on
page 481.
