into T1 or E1 mode and create a logical T1/E1 controller, use the mode command in controller
configuration mode. To disable the current mode and prepare to change modes, use the no form of this

mode {atm | cas}
no mode {atm | cas}
Sets the controller into ATM mode and creates an ATM interface (ATM 0).
When ATM mode is enabled, no channel groups, DS0 groups, PRI groups,
or time-division multiplexing (TDM) groups are allowed, 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 extended super frame (ESF) for T1 or cyclic
redundancy check type 4 (CRC4) for E1. The line code is automatically set
to binary 8-zero substitution (B8ZS) for T1 or high-density bipolar C
(HDBC) for E1. When you remove ATM mode by entering the no mode
atm command, ATM interface 0 is deleted.
Note
(Cisco 2600 series WIC slots only) Channel-associated signaling (CAS)
mode. The T1 or E1 in this WIC slot is mapped to support T1 or E1 voice
(that is, it is configured in a DS0 group or a PRI group).
CAS mode is supported on both controller 0 and controller 1.
On the Cisco IAD2430 series IAD, CAS mode is not supported.
Modification
This command was introduced on the Cisco MC3810.
Support for this command was extended to the merged SGCP/MGCP
software.
This command was integrated into Cisco IOS Release 12.2(2)T.
This command was integrated into Cisco IOS Release 12.2(8)T for the
Cisco IAD2420.
Cisco MWR 2941 Router Command Reference, Release 15.0(1)MR
The mode atm command without the aim keyword uses software to
perform ATM segmentation and reassembly (SAR). This is
supported on Cisco 2600 series WIC slots only; it is not supported
on network module slots.
