Notes:

For this parameter to take effect, a device reset is required.

When the device is locked from the Web interface, this
parameter changes to 0.

To define the administrative state per trunk, use the
TrunkAdministrativeState parameter.
Defines the administrative state per trunk, where x denotes the
trunk number.

[0] = Lock the trunk; stops trunk traffic to configure the trunk
protocol type.

[1] = shutting down (read only).

[2] = (Default) Unlock the trunk; enables trunk traffic.
Defines the line build out loss for the selected T1 trunk.

[0] 0 dB (default)

[1] -7.5 dB

[2] -15 dB

[3] -22.5 dB
Note: This parameter is applicable only to T1 trunks.
Defines static TDM hair-pinning (cross-connection) performed at
initialization. The connection is between trunks with an option to
exclude a single B-channel in each trunk.
Format example: T0-T1/B3,T2-T3,T4-T5/B2.
Note: For this parameter to take effect, a device reset is required.
Enables TDM tunneling.

[0] Disable (default)

[1] Enable
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.
