Normal (CSU) Timing

The typical timing option arrangement is shown in

Figure 5-7. The PBX is looped timed sending data to the TDU

120e which is actually synchronous to the received data. The

Network Interface (NI) is the actual source of all timings.

This timing option is the same as that typically used for

CSUs. This is the preferred mode for use with a PBX

application.

This timing mode works equally well when the PBX is the

source of timing. In that configuration the network would

not be providing timing.

U-BR1TE

The U-BR1TE timing selection works like Normal (CSU)

except that timing is derived from the U interface on port 1.1.

Set Line Buildout

Selects the line build-out for the network interface. In A

UTO

mode, the TDU 120e sets the LBO based on the strength of

the receive signal and displays the selected value. Choices:

0.0 dB, 7.5 dB, 15 dB, 22 dB, and Auto.
