bingo! i wanted to see if i could use a 2620 i had laying around for its T1

the ISP here at work supplies a couple T1 lines which terminate into 1721s

i'd very much like to remove all cisco gear from the network. there are
cisco
7200s as edge routers at the ISP. anybody got advice on the cheapest way to
connect to such routers? the sangoma, accoom, etc. cards are pretty pricey.

That is highly dependent on the technology your ISP is using underneath. In case you already have the 1721s just continue to use them, but remove functionality (i.e. routing) from them --- I recall them as rather simple but solid hardware for terminating circuits.

The cheapest way that I can think of would be to get your ISP to provide
you some sort of Metro Ethernet or Ethernet over TDM solution.

That might be true, but this still depends on how your contract is (e.g. are you renting the 1721 from your ISP or are they yours)... In case your ISP provides them, switching to some kind of Ethernet would exactly do the same thing I suggested above --- the 1721 would simply act as 'dumb' line terminators... Otherwise your ISP would probably charge you something for the TDM termination equipment (EoTDM) or you would have to buy some very specific ethernet equipment (at least the 'right' type of GBICs, which might be as expensive as line cards).

As this is rather OT contact me off-list for further questions.
