Title: Can the DIR-655 accept an RJ-11 connector?
Post by: anonposter on July 15, 2010, 06:16:26 PM

Pretty much as the title states... Can I plug in a RJ-11 connector into the DIR-655 without hurting any of the LAN ports?

Hi,

Ethernet port with RJ-45 connector uses 8 wires....  RJ-11 (telephone type) typically uses only 4 wires.  Can you even secure an rj-11 into a rj-45 port ?

I do not believe this is a good idea....

It's actually not that uncommon when cat5e is run for all structured wiring.  In the building I'm in, cat5e is run for both RJ-11 applications and RJ-45 applications.

The two plugs aren't the same size, the RJ-11 is smaller.

What would you accomplish by plugging the RJ-11 into the router?

RJ11 will indeed fit, but only because it is smaller in size  :)
You will not be able to make a connection.

This might help though: http://www.shoppingcentre.net/shop/rj11-rj45-adapter-p-3807.html

Assuming that you use an adapter for overcoming the pinout discrepancy, the pairing of the conductors in the Cat5e cabling will matter as well.  The minimum conductors for a viable connection are the TX and RX pairs which should each be a twisted pair.

The twisting allows for noise cancellation along the length of the cable, and reduced throughput and collisions will be experienced if you are in a "noisy" environment.

Those "extra" wires in the RJ-45 connector are extremely important.  When I first started to make my own cables, I was not following the wire color coding guides.  Most of these "first cables" were never able to get the 100 Mb/s speeds that the 10 / 100 RJ-45 port can operate with.  As soon as I started following color coding, I can now get 1GB speeds.
