This procedure explains how to set the line direction (west-to-east, east-to-west) on an ONS1580x system on all types of optical amplifiers.
It is necessary to have right line direction on all optical amplifiers so that system can work properly. If line directions are wrong, the system does not start. This procedure is traffic-affecting.
Readers of this document should have knowledge of these topics:
Be familiar with CPTK in order to establish a connection with network elements (NE).
In order to follow this procedure, it is necessary to have Cisco Photonics Tool Kit (CPTK) software installed on a PC running Windows 95 Windows 98 or Windows 2000.
Depending on how you plan to establish the connection with an ONS1580x, it is necessary to have right cable. There are two possibilities:
The information in this document is based on these software and hardware versions:
Point to Point Protocol (PPP) connection
For more information, refer to the CPTK software administration manual.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

To change the line direction of an amplifier:
Connect to the ONS 1580x system (as described in the CPTK software administration manual). The Network Element Inventory Screen opens.
Select an amplifier module by clicking in the column to the left of the module name.
Click on the Action menu and select the Optical Safety Configuration option. The Optical Safety Configuration window opens.
Choose East to West or West to East from the Line Direction list.
If the module being configured is an RBA-10G, select No 24WD-RX or 24WD-RX (enabled or disabled) from the Red Demux drop-down list to specify the red band demultiplexer type required for the module.
Note: Specifying the wrong demultiplexer type can result in a lack of continuous output power in the RBA-10G module.
If the module being configured is a Red band Booster Amplifier (RBA) or Blue band Booster Amplifier (BBA) module, click Yes or No in the Optical Add Drop Multiplexer (OADM) site field to indicate if the module is in an optical add/drop multiplexing site or an optical line site.
