11.5 RDTU Hardware and Cabling
Installation
11.5.1 RDTU Cable Length Switch
The distance between the DK280, RDTU and CSU or
RDTU to other Customer Premise Equipment (CPE)
Tl may vary (O-655 ft.) as shown in Figures 11-1,
11-2, and 1 l-3. The RDTU interface transmitter must
be equalized and its impedance must be matched to
the cable length connecting the RDTU to the CSU or
other CPE, Tl. RDTU transmit equalization/
impedance matching is accomplished by setting
RDTU SW1 for the proper cable length (see Figure
11-5 for SW1 location and Table 1 l-4 for SW1 setting
instruction).
11.5.2 RDTU Loop Back Jumper Plugs
The RDTU PC9 provides jumper plugs for Loop back
testing. Loop back tests are described in Section 11.6
of this chapter.
11.5.3 RDTU Front Panel Indicators
The RDTU PC9 provides seven LED indicators to
show the status of RDTU: Busy or Idle condition,
Alarm status, and Synchronization status. A
description and the function of each status LED is
provided below (see Figure 11-5).
