Adtran Total Access Console Wiring

So Adtran has a series of CSUs and Channel banks under the Total Access line that do not have the "modern" DB9 for accessing the console. As far as i can tell, this involves anything under the Total Access 600 series (600R, 604, 608, 612, 616, 624). I needed to get into one today but found that it only has an RJ45 "Craft" port, and none of my DB9/RJ45 adapters and cable combinations worked. I also found that the internet is plain wrong, and none of their solutions worked correctly, so i took it upon myself to figure it out. Note that the manual indicates that this is a proprietary adapter, however they were kind enough to give the pinouts of the unit itself.

Basically if you don't care about flow control, you can set it up pretty easily with just 3 wires. To make my life easy, i did this with a section of Cat5e and two RJ45 keystones, but you can easily adapt this to be an inline cable or something else.

The first thing i did was map out how my RJ45 to DB9 adapter was wired. I believe this is pretty standard (i checked a few of mine), but you may have to pull yours apart to make sure. In the table NC means not connected and i'm assuming that you are using EIA/TIA-568B for wiring.

The next step was to make the adapter to work for this proprietary Craft port. I took the two keystones and a small length of Cat5e and did the following:

  1. Punch in one end as EIA/TIA-568B (Orange/White, Orange, Green/White, etc.)
  2. Punch in the other end as follows:
    Keystone PinKeystone ColorCable Color
    1Orange/WhiteBlue/White
    3Green/WhiteGreen/White
    5Blue/WhiteGreen

At this point use any straight-thru cable to go from the keystone to your adapter, and to the unit, and you should be done. Note that this is a basic implementation and does not provide flow control, so you will need to disable that. The settings you would want to use are 9600/1/none/none (baud/stop/parity/flow). Also note that this cable can't be reversed, the side terminated normally should plug into the Adtran.

In case anybody is interested, Pin 1 is the Ground, and Pins 3/5 are Transmit and Receive. In this case, the RJ45 Craft port on the Adtran uses 3 for RX and 5 for TX, so you have to swap those around for the sending side. Pins 2 and 8 are used for Flow Control which i did not wire in. Pins 4 and 6 are DTR (Data Terminal Ready) and CD (Carrier Detect) which i also left unattached.


Update: Here is how you would make it if you want to use a pre-made Cisco console cable (one of the teal RJ45 to DB9 ones). Still terminate the first keystone with EIA/TIA-568B, then use this pinout for the second one:
