Cool, not all models have that though.

        Channelized E1 (unbalanced) Port adapter, 2 ports
        Port adapter is analyzed

Enter configuration commands, one per line.  End with CNTL/Z.
rtr-1.alp-hw8(config)#controller e1 4/0 rtr-1.alp-hw8(config-controller)#?
Controller configuration commands:
  channel-group  Specify the timeslots to channel-group mapping for an
                 interface
  clock          Specify the clock source for a DS1 link
  default        Set a command to its defaults
  description    Controller specific description
  exit           Exit from controller configuration mode
  framing        Specify the type of Framing on a E1 link
  help           Description of the interactive help system
  linecode       Specify the line encoding method for a E1 link
  loopback       Put the entire E1 line into loopback
  no             Negate a command or set its defaults
  pri-group      Configure the specified timeslots for PRI
  shutdown       Shut down a E1 link (send Blue Alarm)
 
rtr-1.alp-hw8(config-controller)#

See ? no line-termination command possible. This is a hardwired unbalanced
2xE1 controller.
