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:
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

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
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
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.
