i have recently installed (i had no involvement in purchasing) a 3640 with primary e1 controllers and 2 modules of digital mica modems. users have been complaining of slow connections, upon investigation it seems that the modems are running as v34 with portware of 18.104.22.168. which does not support v90 standard.
On an identical 3640 (which is not yet in use and has no isdn connected to it) i have upgraded the portware to 22.214.171.124 which does support v90 (it is now set as so in s register - s29=6 v.90 modem standard) but if i try to set s30 to anything above 33000 it returns an error and when i do a show modem slot/port under type it shows unknown.
My question is do i have hardware that will not support v90 (the date on the module when i looked was 1996) or does upgrading the portware enable the hardware to support newer standards.
