ATM/Debit cat6 terminations

[Flatbed]

Good Morning,

Is anyone aware of a different sequence for terminating ATM/debit machines? Ran into a situation where the local phone company had to be called in for a service call, to terminate the data line. It was not a T568A/B type termination. Their termination sequence had to do with a more secure encryption.
Any help would be more than appreciated.

Thanks

What is the Cat 6 being used for in the application ?
There is a few different ways the ATM can be connected.
Is it just used as an extension of a telco circuit ?

Their termination sequence had to do with a more secure encryption.

Heh, heh "more secure encription" that what they told you? Was the cable run from an RTU "smart jack" 8 pin jack to the ATM machine?

It was a straight through from the panel, to the jack in the ATM. It is the main communication cable for the machine.

Thanks

Is this one of those ATM's in a store or other such location? It sits on the floor and is the size of, maybe a dishwasher? Or is it a full blown bank ATM?

Yes. One of those privatized machines. We may be getting a service contract with the owner. It would be nice to know the termination sequence. To call in the local phone company for a termination is quite costly.

Dunno. I have done several and they were just a regular phone line. It gets wired just like a phone jack because that's what it is. You saying that yours has an 8 pin jack on it? Why don't you get a hold of the installation or instruction manual. You could also look to see what the phone company did. It's rather inconceivable that the phone company would have some special way of wiring the jack for something like this, especially for "security". Not their job. I think they were pulling your leg.

I agree Hal. It is probably more of a redundant termination. Something to throw-off the average Joe. It may be something so simple as 1 twisted pair reversed.
Thanks for all of your help.

Cheers

Well, I asked some of my telecom buddies this question. Actually seems some have done ATMs that connected to a 4800 baud 4 wire leased data line. 2 pairs, pins 1&2 and pins 7&8. That means 568A or 568B should work just fine as long as the person who connects the end of the wire (I assume the TELCO) does it right.

I assume you ran the CAT6 from the TELCO terminal to the ATM location, installed a 568A or B jack and used a regular patch cord to connect the ATM to the jack? Who connected the other end?

Actually, from server room, to jack. BIX board568A (Canada "EH" - LOL), to jack. Same termination. Patch cord supplied by vendor. Then the local Utility came in and changed the config. on the wall jack. I have not looked at it, as removing the cord, sends an alarm. I do not need any more headaches. Interesting that they are relying on the old 4 pin system. Considering the amount of personal info that is uploaded/downloaded.

Interesting that you are in Canada. Here is what a telecom guy in Canada had to say about this:

Here in Canada, some ATM's use a POTS line and some use DVACS. We also use DVACS for supervised alarm monitoring, lottery terminals, and some interac machines. It is an old schedule 3A data network such as the telex/teletype network which was converted/modified to be used as a supervised data connection. It really is just a supervised 150 baud data network using a F1/F2 Subset (150 baud modem).

This is probably it. They just use it because it's supervised- as you found out. Someone steals the machine and they know about it at the other end.

I'll see if he can tell me what the requirement is for the jack.

Hal,

That is exactly what I am looking for. More so, knowing the why and how, is a big help.

Apparently it works the same way as lotto machines here. The few times I had to do this I just run the cable and leave a long tail hanging out of the wall. The Lotto and TELCO guys take care of the rest.

Well, here in Canada, if we install any jack for the DVACS modem, Bell just ends up ripping it out and hardwiring direct. It requires just one pair between the MDF and the modem. They also like the modem right at the machine, not on the back board. From the modem to the ATM, they use an 8 conductor flat patch cord that comes with the modem.

When I prewire for an ATM machine location, I usually install a blank telco plate and I've seen them fasten a QB terminal box right to the face of it.


So there you have it. I suppose if you don't install a jack they will do what they need to do at the time they connect the service. I don't know why they are charging extra.

Around here, all the local utility terminates is at the entry point. We handle everything else. Actually their advisory in the phone states that they are only responsible for the box on the extrerior of the house. If a customer has any problems inside the house, please contact a qualified electrician. LOL.
I much appreciate the insight into my question.

Cheers

 

[hbiss]

Yeah, BUT you are talking about a data circuit not a telephone line. Most times it will require a RTU that must be installed inside the building and requires testing (loop back among others). The TELCO is responsible for this equipment and it is always installed by them at a suitable location of their choosing.

I have dealt with Gazillions of ATM Installs (cabling, power circuitry, installation and "bringing them up"), and never heard anyone refer to Telephone circuit Pinouts - T568 A vs. B, as anything relating to an Encryption approach (assuming the thoughts are along the lines of "Strong Encryption" - like "128-Bit Encryption).
Only time "A" or "B" questions appear, is when someone runs across a possible mismatching of patch cords vs. equipment.

I am used to "Typical" installs, having at least one 56K ISDN Dedicated / Leased Line per ATM, and a Data cable linking to the MDF on site (for the ATM's PC).

Never dealt with any of those "ATM' ettes" found in Convenience Stores, etc.
Only worked around "Old Big Blue" (IBM), NCR, NEC and Diebold ATM equipment, along with De La Rue TCDs.

Just my 2 cents
