3.   CONNECTING WITH THE AKSYS
DIAL-UP SYSTEM


(Last review or update:  November 30, 2005)
 

A.   Equipment and Software. 

Transmitters and state revenue departments can use the same asynchronous modems and software that they use to communicate with IRS computers.  AKSYS can connect at any standard transmission speed between 2,400 bits per second (bps) and 53,000 bps.

The equipment and software should be set as follows:

            Transmission speed:         2,400 to 53,000 bps
           
Parity.....................              None
           
Data Bits...............               8
           
Stop Bits...............               1

           
File transfer protocols supported:

                       
                        ZMODEM (preferred)
                       
                        XMODEM
                                               
     CRC
                                               
     CHECKSUM
                                               
     1K-XMODEM
                                               
     1K-XMODEM-G
                       
                       

Unless you specify another protocol, AKSYS will assume that you will use ZMODEM file transfer protocol. 

You can change the protocol you use by giving AKSYS two hours notice, and you can change speed at any time without prior notification.  You should use the fastest speed, not greater than 53,000 bps, that your system can support. 

AKSYS's modems are set to negotiate the best error control, data compression, and speed (up to 53,000 bps) and automatically will fallback and fall forward to compensate for varying circuit conditions.  That means that if your modem connects with one of ours at 53,000 bps and during the exchange of data the telephone line conditions deteriorate to a level that will not support that speed, our modem on that system will go to a lower speed.  If the conditions improve, our modem's speed will increase. 

If your modem can connect at 28,800 bps with V.42bis data compression, throughput (the effective rate of data transfer) can be very high -- theoretically, up to 115,200 bits per second.  At that rate, a file of 1,000 acknowledgements could be transferred in about a third of a second.  In actual transmissions, the rate will be substantially slower; however, even without compression, at 28,800 bps a file of 1,000 acknowledgements will transfer in about eleven seconds over a good telephone line. At speeds higher than 28,800 bps, file transfer will be even faster. 

If the connection with AKSYS is made at a slower speed, the transfer rate will be lower and the time required to transfer files will be correspondingly longer. 

B.  Problems That You Might Encounter. 

During your first calls to an AKSYS computer, you could experience one or both of the following problems. 

1.  If AKSYS disconnects almost immediately (1 to 10 seconds) after you have connected with it, the probable cause is that the access code that AKSYS received is not recognizable. Usually, that can be corrected by changing parity.  It is important that you know how to make such changes to your communications software settings in case you have to call AKSYS for technical assistance. 

Your tax software or communications software should provide you with a means of changing certain communications settings.  Although the exact procedures for making changes differ among the different software products, most software will produce a screen that shows the current settings, and it will ask what settings you want to change and what you want to change them to.  If you have called AKSYS for technical assistance, make the changes that were recommended by the technician. 

2.  If AKSYS disconnects, without sending a file to you or receiving a file from you, approximately 30 seconds after your computer has made a connection, the most likely cause is that AKSYS did not receive an access code, or AKSYS received from you a code that it did not recognize. If you call AKSYS technical assistance, the technician most likely will ask you to call your software company to find out how their software can send the access code for you automatically.  If you know how to send the code manually (from the keyboard), AKSYS will accept that.  Make sure that the code that you send manually or that the computer transmits automatically is correct and that the case reflects the response you want from AKSYS: The code must be all in UPPER CASE or all in lower case if you want to receive your current file, and in mixed case  -- the first character in upper case and rest of the code in lower case -- for an online reposting. 

C.     Recommendations and Observations.

During past filing seasons, after they had made their initial tests, AKSYS received very few requests for assistance from software developers or large transmitters.  Nearly all requests for assistance came from smaller direct filers who might not have understood their modem and communications software.

You should understand your modem and communications software manuals, or find someone who can explain them to you.  Understanding how your modem and communications software work can eliminate most of the problems you can encounter in communicating with AKSYS. The following are some of the more common problems reported after a transmitter had connected with AKSYS and had sent his access code successfully. 

1.   The records print on the screen too fast to be read.  Some transmitters do not know how to set up a capture file in which to store the acknowledgement records downloaded from AKSYS.  Before you attempt to retrieve files from AKSYS, you should have established a procedure for storing the acknowledgements to a file on your computer's hard disk.  Trying to read the records as they flash across a monitor screen, or printing the data to a printer, no matter how fast it is, could prove to be unsatisfactory.  Capture the acknowledgements to a file.  Study them later. 

2.   The access code must be in the correct case.  AKSYS will send your current file only when it receives the access code in UPPER CASE or lower case (ABCDEF or abcdef), and it will receive a file of social security numbers, ETINs, EFINs, or Return Sequence Numbers from you for a reposting only when the first letter of the access code is in upper case and the remainder of the code is in lower case (Abcdef)

3.   Some electronic filing software packages include procedures for connecting with AKSYS and for transferring files.  You should make sure that your software will let you use all of the features that AKSYS offers to transmitters.  Some software only will let you receive current files.  Your software might not let you request online repostings.  Ask your software company if their product will let you use all of AKSYS's features.           

4.   AKSYS is automatic.  It communicates very well with other computers.  It is less adept at communicating with humans. You will find your sessions with AKSYS much more productive and shorter if you can automate the procedure on your end.  Design batch files (or have someone do it for you) to automate the process of calling AKSYS, connecting, sending the access code, downloading an acknowledgement file or sending a file to AKSYS (for an online reposting), and disconnecting. 

5.   If you get an error or alarm condition from your computer the instant that file transfer should begin, make sure that you do not already have in your computer a file with that name.  AKSYS names files after the transmitters' access codes.  If your access code is ABCDEF, your current file of acknowledgements for state personal income tax returns always will be named ABCDEF.01.  If you already have file ABCDEF.01 in your computer's download directory, depending on the type of computer and software you are using, and the file transfer protocol, you might not be able to download another file of that name. Rename, relocate, or delete the file in your computer.  Other file names are explained here.

D.   General Instructions. 

Since different brands of communications software and modems have their own unique features, the following instructions are general.  You should adapt them to your specific situation. 

1.           Use the telephone number provided under "Systems Status" at the AKSYS Internet site, http://www.gacaksys.com.  Call an AKSYS computer manually or use the automatic dialing features of your communications software.  All AKSYS online computers will respond to the same system number. Your call will be answered immediately by the next available computer.  Enough computers are kept on line to insure that callers will not get a busy signal. 

2.            When your computer indicates that a connection has been made, not earlier than five seconds -- and not later than fifteen seconds -- following connection send the access code.

3.         As soon as you have sent the access code, you should prepare to receive or send a file.  You will not receive a sign-on message or prompts from AKSYS.  Once you have sent the access code and AKSYS has validated it, AKSYS will send an acknowledgement file to you within fifteen seconds, or it will prepare to receive a file of social security numbers from you. 

4.         After it has sent a current file to you (or received a file from you), AKSYS will disconnect. 

5.         If you did not receive a file, although you were supposed to receive one, a probable cause is that your hardware and software were not set up quickly enough to receive a file.  Automating the procedure on your end can eliminate that problem.

6.         If you are unable to receive a file from AKSYS, call AKSYS technical assistance.  A technician will monitor your call into the system.  He will help you to correct problems, or he will advise you of whom to call for assistance.  AKSYS never can make corrections to your tax software, and only rarely to the way in which your computer is set up.  Only your software company should do that. 

In the past, some transmitters have followed our advice for a day or two then continued with the same procedures that had caused problems earlier.  You should make sure that you correct the problem in your system.  If that requires changing a software setting, you should call your software company for help. 

7.        AKSYS works best when it communicates automatically with other computers.  Some communications software will create an automatic procedure for you.  Check your software manual to see if your software has that feature.
