RGLU2 – Loop/Ground Start CO Line Interface Unit
System:
DK40i Expansion KSU, DK424, DK424i
Circuits per PCB:
four line circuits
Interfaces with:
loop or ground start lines
Older Version(s):
RGLU1 (does not have hookflash to CO)
The RGLU2 also provides ring detection, dial outpulsing, and hold. Each RGLU2 line can be
programmed for DTMF or dial pulse signaling and gas tube secondary protection.
RGLU2 controls, indicators, and interface connectors are shown in
Table 9-17.

RGLU2 Installation

Note The decibel (dB) PAD switches SW101, SW201, SW301, and SW401 control excessive
loudness resulting from close proximity to a central office or PBX telephone office by
providing a -3 dB signal level drop to, or from, the PBX or central office when set to the 3
position. Switches are factory set to the 0 (0 dB signal level drop) position.
➤ To install an RGLU2 PCB
1. If the DK KSU is within one mile of the PBX or central office, set the dB PAD switches
SW101, SW201, SW301, and SW401 to the 3 (-3 dB signal level drop) position.
2. Set each line for ground start (GND) or loop start (LOOP) by setting the following jumper
plugs: SW103 for line 1, SW203 for line 2, SW303 for line 3, and SW403 for line 4.
3. Insert the RGLU2 (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors. RGLU2 can be installed in place of RCOU,
per tables in Chapter 2 – DK40i
4. After installing the RGLU2, gently pull the PCB outward. If the connectors are properly
mated, a slight resistance is felt.

RGLU2 Programming

Programming for the RCOU and RGLU2 is essentially the same. See
Page 9-33, for an overview of RGLU2 programming.
