This option selects the signaling mode of the FXS/DPO.
See Table 6 for detailed descriptions of Mode Options.
2-Wire Termination 600 ohms + 2.16 µF
900 ohms + 2.16 µF
This option selects the impedance of the 2-wire
interface.
Transmit TLP –7.0 to +9.0 dB (+0.0) This is the transmit channel attenuation in 0.1 dB steps.
Receive TLP –9.0 to +0.0 dB (+0.0) This is the receive channel attenuation in 0.1 dB steps.
Trunk Processing Busy in CFA
Idle in CFA
This option selects signaling on the loop during a
Carrier Fail Alarm (CFA).
On-Hook Messaging Disabled
Enabled
When On-Hook Messaging is Disabled, full battery
voltage is provided to the loop when on-hook. This is
utilized to provide compatibility with some station sets.
Note that except for Caller ID, this prevents
transmission in the on-hook state. When Enabled, a
small amount of overhead voltage is reserved for AC
transmission.
NBOC 0 - 126 µF (0 µF) This option selects setting for Network Build Out
Capacitance to balance the FXS/DPO access module to
the loop. Setting should be equivalent to the additional
capacitance added due to the length of the cable.
Tandem Mode Options

options.
Ringback Tone Generation
(2)
Disabled
Enabled
This option is used in PLAR D3, PLAR D4, or FX
Ringdown modes only. When Enabled, the FXS/DPO
provides ringback tone toward the Network.
Defaults are in bold type.
(1)
Only available if Tandem Mode is selected.
(2)

(3)
Only provisionable through software provisioning (reference Software Provisioning on page 6).
