I have a jack in my bedroom where I want to run both an ethernet
connection
and a phone line. I have a modular jack and I can only find RJ45
connectors
for it.

Can I use an RJ45 connector for the phone line using regular phone cable
that I bought at Home Depot? Any details would be appreciated.



First: RJ45 is a well defined standard in a telco environment. It describes
signal names and wires used on a 8p8c minimodular plug/jack. So using the
name RJ45 in an network environment is misleading. It is about the same
common error like using RS232 for a DB25 or DB9 connector.

Then: Wiring the 8p8c connectors for ethernet is deliberatly "standardised"
on using the pins 1, 2, 3 and 6. By plugging a ethernet cable into a
telephone outlet you avoid to connect it to the wires of the pins 4 and 5
which can carry pretty high telephone voltages, fatal for ethernet
equipment.

Wiring one 8p8c outlet for both telephone and ethernet can be done but you
have to use cat 5 UTP cable, at least fot the ethernet part. You can use the
same cable for telephone if you wish, but you can't use plain telephone
cable for the ethernet part. Not reliably.

Somewhere outside the outlet you have to split the cable. Where I live they
are for sale in any DIY shop where it is named ISDN splitter.
