WIC-1T supported speeds

something weird happened to me.

i have 2 routers going trough a mux.

3660(wic)-----(db60)2509.

when i connected 2 routers this way the serial ptp would never come up.

(i have to point out that both routers are being used normally as DTE's)

i changed the 3662 for a another 2509 and the serial would come up no problem.

i changed wic's on the 3662 thinking i probably had a bad one. no change. finally i changed the clock rate the mux was delivering to the 3662 and everything started working. i started looking into things deeper and noticed somethign really funny:

that the serial would only come up with certain speeds configured on the mux, here's a few of them:

-64k

-256k

-2048k

-1280k

-512k

but, for example, it wouldn't come up with:

-1920k

-616k

remember that if i changed the 3662 and used a plain old 2509 with a db60 interface any speed would work.

my question is:

is a wic card restricted to work only with 'certain' speeds provided by the dce equipment? and the db60 traditional cisco serial works with any speed provided by the mux?

Re: WIC-1T supported speeds

The WIC-1T should be able to take in any clock rate, and I don't see any bugs or HW issues that should prevent this. You may want to open a case with the TAC to pursue this further, after you have tried the latest code (although SW should not be a factor).
