IRING
HDSL and subscriber wiring are threaded through rubber grommets at the bottom of the RT. Subscriber line
connections are made through the right-hand side of the Line Modules. Use a No. 1 Phillips screwdriver to punch
two small holes in the bottom of the rubber grommet on the left-hand bottom side and one small hole in the
right-hand grommet of the RT.
Be careful when installing or modifying telephone lines. Dangerous voltages can be present. It is unsafe to
install telephone wiring during a lightning storm. Always disconnect all telephone lines and power
connections before servicing or disassembling this equipment.
All wiring external to the product should follow the local wiring codes.
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 COLU, because dangerous voltages are present on the HDSL
pair.
The COLU, unless previously disabled by means of Craft provisioning, periodically attempts to power up
the RT by ap130 Vdc with respect to ground to the HDSL pair. The COLU also initiates a start-up
after a momentary short has been applied to the HDSL pair. The COLU responds with start-up voltage 3
seconds after removal of the short.
Cutting the grommet with a utility knife or something similar is not recommended, because this can cause
too large an opening thus allowing contaminants to enter.
