Test Function (Switch 2 – Test Mode)
Switch Position Type
Up (default) Built In Link Test (BILT)
Down Loopback
Built In Link Test: Set Switch 2 to the Up position for the C/CM-
10GT media converter module to initiate the Built In Link Test on
port 1. These tests consist of the media converter module
generating test patterns to be sent out on port 1 to the remote
media converter module. If the remote media converter module is
also a compatible 10GBaseT media converter module then the
remote media converter module will automatically be put into test
mode.
Note: The BILT can operate on 10G modules. This feature can
also be used with Perle S-10G media converters
Loopback: If Switch 2 is down, the specified port will be forced
into loopback mode (switch 3 determines the port number). Data
received on the receiver (RX) will be looped back to the transmitter
(TX) connection. This mode is not used in conjunction with BILT. It
can be used when other data generation methods are used.
