VT tunnels allow VT circuits to pass through intermediary ONS 15327s without consuming VT matrix
Note
resources on the cross-connect card. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT
tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer
to the Circuits and Tunnels chapter in the Cisco ONS 15327 Reference Manual for more information.

Name—Assign a name to the VT tunnel. The name can be alphanumeric and up to 48 characters
(including spaces). Circuit names should be 44 characters or less if you want the ability to create
monitor circuits. If you leave the field blank, CTC assigns a default name to the tunnel.
Type—Choose VT Tunnel. The Bidirectional, Number of Circuits, Field Size, and Create
cross-connects fields in the dialog box become unavailable.
Size—Unavailable for VT tunnels.
Bidirectional—Unavailable for VT tunnels.
Number of circuits—Unavailable for VT tunnels.
Auto-ranged—Unavailable for VT tunnels.
State—Choose a service state to apply to the VT tunnel:
– IS—The VT tunnel is in service.
OOS—The VT tunnel is out of service. Traffic is not passed on the circuit.
–
OOS-AINS—The VT tunnel is in service when it receives a valid signal; until then, the tunnel
–
is out of service.
OOS-MT—The VT tunnel is in a maintenance state. The maintenance state does not interrupt
–
traffic flow; it suppresses alarms and conditions and permits loopbacks on the tunnel. Use
OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS,
OOS, or OOS-AINS when testing is complete. See the
on page 8-8.
