 RJ45 to RJ11 Patch Cord
I would be intrested in making a RJ45 to RJ11 Patch cord. On the I/o I have terminated pairs 4,5 ,7,8. I would like to use a RJ45 jack towards that end. The other end which goes in the telephone instrument has got to be a RJ11 connector. Kindly let me know can i do the same and if possible how do i crimp the RJ11 connector which just has 4 pins

Dear Amit,

Please explain what you are trying to do with this patch cord. The infomation provided is incomplete. Pins 4 & 5 of the pin plug (RJ45) is considered pair 1 and pins 7 & 8 is considered pair 4. The RJ11 actuals has 6 pins but but with on 2 connected (pins 3 & 4), an RJ-14 has 6 pins with 4 connected (pins 3 & 4 are line 1 and pins 2 & 5 are line 2). Are you trying to connect 2 line to a telephone?
