RJ45 and RJ48 question

We are about to switch ISPs and currently our ISP provides us with our CSU/DSU so we have purchased a new cisco 2611xm router with a WIC-1DSU-T1 card for our CSU/DSU.  Currently our ISP uses a cable with RJ45 connectors on both ends to go from thier box on the wall  to their CSU/DSU. We are switching to Bellsouth and they tell me their box/demark will have an RJ48 female jack.  I know that an RJ45 cable can plug into an RJ48 outlet with no problem (not visa versa though).  The WIC-1DSU-T1 CSU/DSU has a female RJ45 outlet on it.  My quesion is what kind of cable to I need to go from the new Bellsouth RJ48 to the WIC-1DSU-T1. According to


i need a RJ-45 to RJ-45 straight-through cable (provided by customer) but will this work since the Bellsouth demark is actually a RJ48?? and will the inouts be correct??

Since the rj-48 in this scenario is pin'd the same as an rj-45 (using pins 1/2 and 4/5) you'll be fine.
Just make sure you leave your current connection active till you have tested. On switch over day just try it and you can always switch back.
