NSTALLING
THE
DICOLU
You can install the DICOLU in any slot except the three positions labeled COMMON, MUX 1, and MUX 2. Refer
to the cabling tables provided in the COTS documentation for slot and Telco cabling assignment.
1
Open the retaining latch on the front of the DICOLU.
2
Insert the DICOLU into the card guides in a vacant slot in the COTS that corresponds to the location of the
wiring from the CO switch. Engage the retaining latch to hold the card in place.
Always treat the HDSL pair as if it were live with high voltage present. Use caution when installing an
HDSL pair that is already connected to a DICOLU, because dangerous voltages are present on the HDSL
pair. The DICOLU, unless previously disabled by means of craft provisioning, periodically attempts to
power up the RT by ap 100 Vdc with respect to ground to the HDSL pair. The DICOLU also
initiates a start-up after a momentary short has been applied to the HDSL pair and responds with start-up
voltage three seconds after removal of the short.
Electrostatic Discharge (ESD) susceptibility symbols indicate that a device or assembly is susceptible to
damage from electrostatic discharge. You must wear an antistatic wrist strap connected to the appropriate
ground connection prior to performing installation procedures. You must also observe normal ESD
precautions when handling electronic equipment. Do not hold electronic plugs by their edges. Do not touch
components or circuitry.
