Appendix A
Many NT1's have settings
available to turn Termination
ON or OFF. If the setting is
ON they may also have
settings to select either 50 or
100 Ohms.
Sometimes these settings are
accomplished via switches,
other times they are done with
jumpers.
Follow the NT1 manufacturer
instructions to set the
Termination to ON or OFF as
needed.
Timing
NT1's also have a timing
setting with the options FIXED
or ADAPTIVE.
On some NT1's the options
may be labeled PB or PTP.
PB is equivalent to FIXED and
PTP is equivalent to
ADAPTIVE. Timing settings in
the following discussions are
based on NT1 manufacturer
recommendations.
