<musing> If 3Com is listening, as I've mentioned to TG in the past, like to see 3Com come out with a DS3 <-> CT1/PRI interface internal to the hub. Even if it'd take up an entire chassis to do it, it'd be really cool to be able to plug in twin coax on the back of a chassis and be done with it, turning things up as needed but working on the DS3 level instead of having a mess of wires running around everywhere from the DS3 interface to the mux, to the dsx panel to the DSP's, etc. I don't know if the packet or TDM bus is designed to handle that much data, however. I would hope that it is. Heck, I wouldn't mind having a DS3 card which would interface to the DSP's across the TDM bus as long as we could get dual PRI or dual T1 DSP's in place. Wouldn't that be cool? :) It would mean making those LED's a bit smaller so we could see if span 1 is working vs span 2 on the dual DSP. Let's see... 28 / 2 = 14. If the DS3 card took up one one slot, that'd be 15 slots with the DSP's. Hmmm :) One for the serving gateway card, and one for the NMC... :) Sounds like just the right size to me... Am I the only one who thought of this? :) The only real disadvantage to doing this is putting so many eggs in one basket with the chassis being required to be up. If we were going to do this, we'd definitely have spare DS3 equipment on hand and thanks to a very nice arrangement with our telco, they've installed an FLM150 in our offices where we have DS3 and that's their responsiblity. As far as dual DSP's, we'd probably keep a couple on hand along with spare power supplies and a chassis. If we were going to put that much $ into a box, though, I'd definitely want to be able to peel off some of those DS1's into external RJ45's to be used by other CSU/DSU's so we could put DAP customers, etc. on it. </musing> Kevin E-Mail: s1kevin@tims.net Web: http://users.sota-oh.com/~s1kevin/ Unsolicited advertisements processing fee: $50 subject to change without notice - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
