Chapter 7 Circuits and Tunnels

7.2.1 Concatenated STS Time Slot Assignments

Note You cannot set up VT circuits to terminate on an ONS 15600 node. However, you can create both STS and VT circuits that have an ONS 15454 or ONS 15327 source and destination with an ONS 15600 as a pass-through node. For information on VT circuit creation and tunneling, refer to the circuit chapters in the Cisco ONS 15327 Reference Manual and the Cisco ONS 15454 Reference Manual. Note that you cannot mix protection schemes, for example, 1+1 to path protection. Acceptable schemes are unprotected to unprotected, 1+1 to 1+1, BLSR to BLSR, and path protection to path protection.

7.2.1 Concatenated STS Time Slot Assignments

Table 7-1shows the available time slot assignments for concatenated STSs when using Cisco Transport Controller (CTC) to provision circuits.
