DISC Commands


DISC Commands

This chapter provides disconnect (DISC) commands for the Cisco ONS 15454 SDH, Cisco ONS 15454 M2, and Cisco ONS 15454 M6.

NoteAll commands supported on the Cisco ONS 15454 SDH platform are also supported on Cisco ONS 15454 M2 and Cisco ONS 15454 M6 platforms.


The Disconnect Test Access (DISC-TACC) command disconnects the TAP and puts the connection back to its original state (no splits). The DISC-TACC command applies to the Cisco ONS 15454 SDH platform. For more information on TACC, refer to the Cisco ONS SDH and Cisco ONS 15600 SDH TL1 Reference Guide .

Usage Guidelines

For this command to be applicable, you must first create the TAP using the ED-<VC_PATH> or ED-VC12 command.

The following actions will return error messages:

  • If you send this command to an already disconnected connection, a SADC error message is returned.
  • If the system cannot release TAP, an SRTN error message is returned.

NoteIf the test access connection is intrusive, the original state of the facility/path is restored after this command is executed. Test access connections are dropped automatically if the TL1 session is terminated or is timed out.
