 Connect Phone Wire into RJ45 Female
I have a pair of telephone wire coming out from the wall. Is it possible to connect the telephone wire from the wall into a RJ-45 (female) Keystone Jack and used a RJ11 male connector to connect to the telephone? If so, where do I connect the telephone wire from the wall into the RJ-45 (female) Keystone Jack. The RJ-45 (female) Keystone Jack have eight connection.

Dear Lan,

Yes it can work perfectly. Most 8 pin modular jacks made for category 5e include color coding for both T568A and T568B wiring schemes.
For a home it is recommended that you use the T568A as this follows the color code for both an RJ-11 (one line) and an RJ-14 (2 line) telephone.
Line 1 is on the White-Blue pair and line 2 is one the White-Orange pair. The male plug on the telephone line cord will center in the 8 pin modular jack. See this link for the pin outs:
