Any backwards compatibility issues with FT1 CSU/DSU modules?

I'm building up a bunch of 2620's using WIC-1DSU-T1 modules. It looks like I have a bad module and was wondering if an older FT1 CSU/DSU would work in the new routers. The new modules have a hardware code of PQUICC and the older WIC has HD64570. This older module is at a remote location in a 2524 so I'm unable to test until I travel out there to do the router swap..

Anywone know offhand if there will be a problem? TIA.

Craig

According to me, the 1600 and 3600 series routers support the fractional T1 CSU/DSU card. Not sure if 2600 supports it. You could try you luck and let others know if it works.

25XX modules are not WICs and will not even fit into a 26xx router.

Sorry,
