Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

(OP)
I got a PRI from my provider, which I want to connect to my Avaya PBX.
Problem is they are in different rooms and I currently only have Cat5e Ethernet cables running between the two rooms.
Do I need to run a T1 cable or can I just use an Ethernet cable, just crimp that to T1 pinout?

In other words, are there any substantial differences between a factory T1 cable and an Ethernet cable (other than the pinouts), that would necessitate using a T1/PRI cable instead of a CAT5e?

RE: Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

Yeah. I mean, I'd suggest shielded cat 6. But some providers deliver from an Adtran device that hits a MM710 with a plain old cat6 straight through just fine.

(OP)
The PRI will come off of an Adtran.
Do I have to worry about pinouts at all, or can I just use cat5e (or cat6) without recrimping the cable pins to match what would traditionally be required for T1?

RE: Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

ds1 cables are shielded transmit and receive pairs. Ethernet cat5 and cat6 are not.
The wrong cables will cause grief with slips and misframes that are neither pbx hardware or provider circuit issues.
These issues will also occur if you run t1 circuits through inside wire and tie cables or house cable between floors.

Use the right cable(s)

This is a good read,

I've used Cat5e for temporary installs and currently using it for ONE permanent install but it is a short equipment to equipment run and have had no issues so far with slips or misframes.

I do agree with AvayaTier3,
Always best practice to use correct cabling.

So in the UK we have to use specific E1 primary rate cables , I have used both the 3 mile long ones that Avaya sell you for £10 sqillion , and as Kyle suggested shielded cat 6 with correctly terminated shielded plugs that I home made , both worked , but if you are unsure go with the Manufacturers cable , it takes out any worry if you do get issue's

Not that they mean a thing anymore , get a brain dump pass the test crash the system.

RE: Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

Yeah, I saw them on short runs too but with 1 or 2 errored seconds per 15 mins. You can get away with it. I wouldn't recommend it unless you're well versed in dealing with carrier isdn guys though. First problem you have that's completely unrelated and they'll hang on to that till you change the cable!

RE: Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

(OP)
So I assume this Avaya 700395445 120A CSU CABLE would be the way to go for me?
DS1 cable

I will be using TN464HP with CSU 120A5 on CM3.0

RE: Use Ethernet cable instead of T1 cable for PRI, just crimp cable to different pinout?

Yes and if you ever run into issues
