D-Link DI-624 Wireless Router unable to split a T1?

[Polishwonder74]

I just read a little something at Buy.com:
buy.com review

This guy is complaining that he had trouble splitting a T1 with his D-Link DI-624 Wireless router, called customer support and they eventually told him that his router just flat out won't do it.

Does anyone know whether or not this is actually true? I'm thinking of buying one, they're on sale.

nope...a t1 needs a CSU/DSU and a router.

Uh, how are they doing it at Tom's then?

that is totally wrong. I used Dlink 614+to support about 45 computers before I put a firewall router.

I'm not entirely sure if my post is correct but I'll try to explain anyway. The universities probably already have a CSU/DSU and router (as spidey07) mentioned. The students are just hooking up their router as a switch or a router onto a router. Tom's Hardware recommends using either a switch or a router with DHCP disabled (which essentially makes it a switch). Hope this helps.

Well, I had a nice detailed explanation of why you cant do this typed out, but apparently either Anandtech's servers or my ISP decided to take a momentary leave of abscence, and I lost the post when I hit reply. I'm not gonna type it all again, so here's the basics of it

Basically, T1 is a different physical medium than Ethernet. If there is a T1 coming into the dorm, theres a dedicated CSU/DSU terminating it, and router translating it into Ethernet. Ethernet is what goes into the dorm rooms and what they're plugging into their routers.

You cant terminate a T1 with router that only has Ethernet ports on it, gotta have the CSU/DSU.

aw man, isn't it always the way?? Type up a real nice response and it gets sucked into the black hole never to return.

Thanks for the effort though. I was pretty sure you must be able to split up a T1 with that router, probably by disabling the dhcp stuff and let the school's routers handle the new IP's

If there is no CSU/DSU on the router (which there isn't...not on that kind of a router) then you cant. Period. End of story. Close the book.

Plugging a T1 circuit into an Ethernet port and expecting it to work is like having someone speak Farsi to a West Texan and expect them to understand and comprehend everything. T1 and Ethernet are different languages, so to speak. You can think of a Router with a CSU/DSU in it as a translator. Without a CSU/DSU, the router is just another West Texan that doesn't know how to speak Farsi.
