10 DATA COMMUNICATION SETTINGS
This section describes attributes used to configure and read out misc data communication
settings.
10.1 NCP – Node Communications Path
This attribute reads and configures node communications path.
10.1.1 Usage
Attribute type: Read and write
This attribute is used to read and configure what rack position the fiber optic repeater /
slave node is connected. This configuration is used when performing optical loss
adjustments (ACT OLA) from slaves to masters and for trouble shooting purposes. For
this reason it is important to configure the Node Communications Path.
Format on getting parameter:
Rack1:Slot1 Rack2:Slot2 .. Rack24:Slot24
where
RackN:SlotN indi cates rack (1..4) and slot (1..6) where node N is installed.
If configuration for node is not made, 0:0 is replied.
If node is not configured, a '-' (dash) is replied.
Example:
GET NCP
Reply:
1:1 1:2 1:3 1:4 0:0 2:1 2:2 2:3 3:1 - - - - - - - - - - - - - - -
meaning that system has 9 nodes, but node 5 does not have node communications path
configured.
Format on setting parameter:
SET NCP <Node#> <Rack>:<Slot>
where
<Node#> determines node to be configured (1..24).
<Rack> is the rack (1..4) and
<Slot> is the slot (1..6) containing Fiber Optic master used to communicate with slave.
Example:
SET NCP 5 1:5
configures node 5 as being connected to fiber optic module in rack 1, slot 5.
10.2 OCP – Opto Communication Path Configurations
This attribute is used to read and enable/disable communications over opto fiber.
10.2.1 Usage
Attribute type: Read and Write
For trouble shooting purposes and to disable data from a fiber optic device that pollutes
communications data with other slaves it is possible to enable or disable data
communications over the opto fiber connected to a certain FiberOptic Master Unit.
Format on getting parameter:
<OCP:1:1> .. <OCP1:6> <OCP2:1> .. <OCP4:6>
where OCP1:1..OCP4:6 indicates enable / disable communication over fiber connected to
fiber optic masters in <rack 1, slot 1> .. <rack4, slot 6>.
0 means communications path is disabled.
1 means communications path is enabled.
If optical master is not configured, a '-' (dash) is reported in corresponding position.
Example:
GET OCP
