RJ45 or RJ48?

To date, we have always used standard RJ45 leads on all our E1 voice PRIs. Most of the CCO documentation refers to using an RJ48 lead.

Does is matter? If yes, what affect can the RJ45 have?

thanks

Mark.

Re: RJ45 or RJ48?

I don't know that it matters. You can use a standard Cat5 patch cable with the correct pinouts as long as the cable length is not too long. If it's a longer cable run then you would want to look into T1/E1 quality cable with a better wire gauge.
