I'm a little confused about the status of support for E1 connections on IAD2431-1T1E1 devices. Nearly all the documentation I read for this device says that it has 2 T1/E1 ports. However when I read the release notes for IOS release 12.4 it states...
'One or two T1 ports for WAN connection or with channel-associated signaling (CAS) for connection to a digital PBX, except for the Cisco IAD2430-24FXS IAD, which supports none. E1 ports are currently not supported.'
What do they mean 'E1 ports are currently not supported'? Does this mean that the T1/E1 ports are just really T1 ports or can they really be used to connect to another E1 device?
FYI...we are wanting to implement a SIP gateway connecting to our existing IVR servers running Dialogic D/600JCT-1E1 E1 cards so any advice on a good device to do this would be appreciated.
Thanks in advance!
