mode (ATM/T1/E1 controller)
mode (ATM/T1/E1 controller)
To set the DSL controller into ATM mode and create an ATM interface or to set the T1 or E1 controller
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
command.
mode {atm | cas}
no mode {atm | cas}
Syntax Description
Command Default The controller mode is disabled.
Command Modes Controller configuration
atm 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 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.
cas Sets the controller into 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.
