Determines the Tx clock source of the E1/T1 line.

[0] Recovered = Generate the clock according to the Rx of the
E1/T1 line (default).

[1] Generated = Generate the clock according to the internal
TDM bus.
Notes:

The source of the internal TDM bus clock is determined by the
parameter TDMBusClockSource.
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 for all trunks.

[0] = Lock the trunk; stops trunk traffic to configure the trunk
protocol type.

[1] = Shutting down (read only).

[2] = Unlock the trunk (default); enables trunk traffic.
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 depicts the trunk
number.

[0] = Lock the trunk; stops trunk traffic to configure the trunk
protocol type.

[1] = shutting down (read only).

[2] = Unlock the trunk (default); 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.
