Let me explain our requirements for the POS terminal network. We have POS terminals with embedded V.34 standard modem protocol. Important note: Connection between terminal and telecommunication provider is plain data protocol there is not any higher protocol like PPP.
Connection and data flow:
The modems will establish dial up connection to E1 line to the Router. E1 Router will take the data from the modems and encapsulate it with TCP protocol. Encapsulated TCP packets will be sent to the TCP server that will listen on some IP address and PORT. The TCP server will respond to every connected modem according to its request. So please let us know if you can help me with configuration on this kind of scenario on Cisco as5350.
Wow that is going back some time. It's probably been more than 10 years since I seen such a configuration.
I found this reminder:
You need to configure the range of configured lines to use the autocommand and telnet.
line 1/3/xx 1/11/yyy
autocommand telnet <server ip> <server port> /stream
Accepting credit cards is a great way to increase the amount of the average sale for your business, offer customers more payment convenience -- and send your blood pressure through the roof from time to time.
To assure you're as prepared to troubleshoot at the point of sale as you can possibly be, make sure you have seven areas covered:
With those in place, you'll minimize problems. However, life will remain interesting. Here's what Bank One recommends you do in tight spots:
First, ensure that you review all procedures with new employees -- even if they may not immediately be responsible for processing sales. Make sure that your policies and practices are consistent, fair and efficient.
Problem: A customer wants a cash refund for merchandise purchased on a credit card.
Answer: "I'm sorry, ma'am, credit card purchases can't be returned for cash because processing requirements for credit cards and cash transactions are different. I can give you a credit card voucher, though."
Problem: How much money should you keep in your account to cover such things as chargebacks, discount fees and annual fees?
Answer: Bank One recommends keeping at least twice your average ticket amount plus your normal balance. Your account shouldn't overdraw.
Problem: "Boy, we're getting a lot of problems with returns."
Answer: Post a clear return policy near your register, and include your return policy on the sales receipt. Your customers know what the deal is, and it gives your sales staff something to back them up with customers.
Problem: "I had a guy the other day whose card stripe was worn, and he insisted I manually enter the number. I did, and it was fine, but it was just a little suspicious."
Answer: Any time you swipe the card and it won't go through, key-enter the card number and expiration date. But be sure you make an imprint of the card and have the customer sign the sales draft. Suggest that the customer request a new card from their card issuer. If it looks fishy, call for a Code 10 authorization -- voice authorization for suspicious transactions.
