RE: RJ48-RJ48 cable [7:70596]
A regular cat5 ethernet cable would work. It used pin 1,2,4,5.

RJ-45 and RJ-48 as used for a T1 circuit are effectively the same. As long as the distance is not too great from the demarc to the router, Cat 5 UTP cable can be used. For long distances, shielded UTP is called for. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thomas N Sent: Thursday, June 12, 2003 1:39 PM To: [EMAIL PROTECTED] Subject: RJ48-RJ48 cable [7:70596] Hi All, I am wondering what is the difference between the RJ48 and RJ45 connector/cable?

Thanks >in advance! > >Thomas. An RJ48 connector is basically an RJ45 connector with only pins 1,2,4 and 5 terminated for a T-1. I don't recall if there are any other differences. I think just about any short, straight-thru, flat satin cable will work just fine. Many of them have ferrite rings on them for noise reduction, I believe. In a pinch a straight thru Cat 5 cable would work just fine. There may be some technical reasons why you wouldn't want to use twisted pair cable, but I don't know about them. I try not to use UTP unless I have to, though. Someone else here is bound to have more technical details and they can fill in what I've neglected to mention or correct any mistakes I made.

Thomas, You can use a straight-through CAT5 or CAT3 patch cable. The difference is in the meaning of the pins. From a cabling perspective it doesn't matter. - Tom Thomas N wrote: > Hi All, > > I am wondering what is the difference between the RJ48 and RJ45 > connector/cable?

Yah you can use 1,2,4 and 5. Here 1,2 and 4,5 are Tx and Rx pairs and you have to reverse them once to have SPs Tx at your Rx and vice versa.

Re: RJ48-RJ48 cable [7:70596]
Thanks Scott! So if I didn't understand it wrong, I can just use a regular CAT5 Ethernet cable (with all 8 pin) to connect the WIC-1DSU-T1 on the router to that RJ48 hand-off connector from the ISP?
