Cisco ONS 15454 SDH Product Overview

Cisco Transport Controller

When a bidirectional signal fails, both the transmit and receive signals switch

away from the point of failure (the port or card). A unidirectional signal switches

only the failure direction, either transmit or receive.

Protection Channel Access (PCA)

1:1 and 1+1 protection configurations utilize only a portion of ring bandwidth.

The remaining bandwidth is idle until a switch occurs. PCA circuits run through

the idle bandwidth on 2-fiber and 4-fiber MS-SPRings. Since they are considered

to be lower priority, PCA circuits are pre-empted when a switch occurs to make

room for the protected circuits. They are restored when the protected circuit is no

longer needed. PCA circuits help you to utilize networks more efficiently by

lowering overall network cost per bit, leveraging untapped network bandwidth,

and sharing network costs across a larger service base. ONS 15454 SDH PCA

circuits are compliant with Telcordia GR-1230-CORE Section 3.4.

Cisco Transport Controller

Cisco Transport Controller (CTC) is a software program that gives you control of

OAM&P activities for the ONS 15454 SDH. The program is automatically

downloaded from the TCC-I card to your workstation when you connect to the

ONS 15454 SDH. CTC also provides a setup wizard that installs the files needed

to use CTC on a PC or Solaris workstation.

Graphical User Interface

The CTC graphical user interface (GUI), also called the CTC window, provides

three primary views, or modes. These modes include:

• Network view—Provides information about the ONS 15454 SDH network

and displays a user-defined map with ONS 15454 SDH nodes represented by

colored icons. The color of the icon represents the node status. You can

perform network management tasks or display any node in this view. See the

“Customized Network View” section on page 24 for information about

changing the default network map and adding domains.
