Hi George,
Have a look at that same link I posted earlier, it says about the
framing etc...I've copied it below for you. I didn't configure anything
on the e1 controller expect the clock source and mode atm. I just left
the rest as defaults. It might well be your IOS version. I don't have
access to CCO anymore but I know these two IOS's will do atm on my 3810's :
mc3810-a2isv5-mz.120-7.XK3.bin <--32M RAM
mc3810-a2jk8sv5-mz.122-16.bin <-- 64M RAM
http://www.cisco.com/univercd/cc/td/doc/product/access/multicon/3810soft/cmdref/e1t1ref.htm#26726
To set the mode of the T1/E1 controller and enter specific configuration
commands for each mode type, use the mode controller configuration
command. Use the no form of this command to restore the default mode of
the controller.
mode {atm | cas | ccs cross-connect | ccs frame-forwarding }
no mode {atm | cas | ccs cross-connect | ccs frame-forwarding }
Syntax Description
atm
Sets the controller into ATM mode and creates an ATM interface (ATM 0)
on the Cisco MC3810. When ATM mode is enabled, no channel groups, voice
groups, PRI groups, or TDM groups are possible, because ATM occupies all
the DS0s on the T1/E1 trunk.
When you set the controller to ATM mode, the controller framing is
automatically set to ESF for T1 or CRC4 for E1. The linecode is
automatically set to B8ZS for T1 or HDBC for E1. When you remove ATM
mode by entering the no mode atm command, ATM interface 0 is deleted.
ATM mode is supported on controller 0 only (T1 0 or E1 0).
Regards,
Glenn.
