Modem Cables
RocketModem ports use standard telephone-type
unshielded twisted-pair cables with RJ11 modular
connectors. These can be purchased anywhere commercial
telephone products are sold.
If you choose to build your own cables, use the following
information. When building cables, use Category 3 (or
better) unshielded twisted-pair wiring.

Safety Notices
Installation of inside wire may bring you close to electrical
wire, conduit, terminals and other electrical facilities.
Extreme caution must be used to avoid electrical shock
from such facilities. Avoid contact with electrical current
by following these guidelines:
•
Use tools with insulated handles.
• Do not place telephone wiring or connections in any
conduit, outlet or junction box containing electrical
wiring.
Note: Do not work on your telephone wiring at all if you
wear a pacemaker. Telephone lines carry electrical
current.
• Telephone wiring must be at least 6 feet from bare
power wiring or lightning rods and associated wires,
and at least 6 inches from other wire (antenna wires,
doorbell wires, wires from transformers to neon signs),
steam or hot water pipes, and heating ducts.
• Before working with existing inside wiring, check all
electrical outlets for a square telephone dial light
transformer and unplug it from the electrical outlet.
Failure to unplug all telephone transformers can cause
electrical shock.
• Do not place a jack where it would allow a person to
use the telephone while in a bathtub, shower,
swimming pool, or similar hazardous location.
• Protectors and grounding wire placed by the service
provider must not be connected to, removed, or
modified by the customer.
CAUTION: Do not touch telephone wiring during
lightning!
