Compliance Codes
Table 2 shows the Compliance Codes for the Total
Reach DDS-R and the T400/T200 housing when
installed together. The Total Reach DDS-R
Standalone unit complies with the requirements
covered under UL 1459 third edition. The Total
Reach DDS-R Standalone unit is intended for
installation in restricted access locations only.

NOTE
The DDS customer port is classified as suitable
for connection to intra-building or non-exposed
wiring only.
LED Indication
The Total Reach DDS-R front panel LEDs display the
operating status and service rate. The LEDs are
described in Table 3.
Signal Meter
The Total Reach DDS-R front panel signal meter
approximates the amount of dB loss on the Total
Reach DDS loop at 13.3 kHz (135 Ω termination), the
Nyquist frequency of Total Reach DDS. The signal
meter on the Total Reach DDS-R can be used to verify
that the loop loss is within Total Reach DDS
deployment guidelines without the requirement of
peripheral test equipment. The signal meter is
activated automatically upon power-up during the
Total Reach DDS training sequence and remains
activated until synchronization occurs (usually 30-90
seconds after power-up). If the signal meter only
illuminates the 2.4 LED, then the loop loss is too great
for Total Reach DDS deployment. If the signal meter
illuminates 2.4 and 4.8 (two LEDs), then the Total
Reach DDS loop loss is between 50 and 56 dB and the
loop is considered marginal for Total Reach DDS
deployment.
