for PSTN support<BR></FONT><BR></DIV>
<DIV></DIV>Hi. Does anyone knows for sure if this T1 (2 port) Multi-Flex
Trunk WAN daughter card VWIC is supported using the 2 T1 ports for voice to the
PSTN??? I read a docuement which I'm not clear with what it says: <BR><BR>
<UL>
<LI>Enhanced clocking capabilities--The 2-port MFT VWIC2s can enable each port
to be clocked from independent clock sources for data applications. This
independent clocking capability is not supported for voice applications and
not supported with the AIM-ATM-VOICE-30 module.
</LI></UL><BR><BR>http://www.cisco.com/en/US/products/hw/modules/ps2617/products_configuration_example09186a008052c920.shtml
<BR><BR><BR>I've had clocking problems with slips errors on the controllers even
using the network-clock participate and select commands for example:
<BR><BR>network-clock-participate wic 0 <BR>network-clock-select 1 T1 0/0/0
<BR><BR>In this scenario controller T1 0/0/0 will give me no errors but 0/0/1
will have slips for example. I can live with this errors but faxes don't.
