Managing Ports and Lines
2. Enter the identification information for the new line, and associated
port.

The Line ID will be checked for uniqueness and is case sensitive.
The maximum length is 50 characters. An automatically generated
name is proposed, with an incrementation to avoid overwrites.

If the line is to be matched to a switch port, select the switch in the
list of available choices. If no switches are available, you can only
select the OTDR. In the case of cascading switches, select the last
switch in the link to match the line and port.

Once the switch is selected, you can select the port you want to
associate to the line. The maximum length is 50 characters, and
the name is case sensitive. If you only have an OTDR in your
system, this field is disabled.
Note: If the switch is an FG-750, the port name is usually the slot the switch
module is in, and the port, separated by a comma. For example if your
switch is in slot C, and you are using the second port, then the port name
will be C,2. If the switch is an external model (Node OTAU, identified as
“Sumitomo”), then the port will be only the corresponding number.
3. Click on Add to add the line.
