Configuring a Line Interface

An OCx module can have one, two, or four line interfaces.

To configure a line interface:

1. In the Instance Explorer, select the line interface you want to configure.
2. Right-click, and select Configure.

The OCx Config tab appears in the work area.

3. Set the line interface parameters (Table 38).

 Table 38:  Line Interface Parameters 

 Field
 Description

 Name

 Identifies the interface; generated automatically


 Alias

 Description of the interface; 0-15 characters; default: blank


 IfIndex

 Identifies the interface on the particular line interface; generated automatically


 Operational

 Current operational status of the interface


 Administrative

 Desired status of the interface: Up/Down; default: Up


 Transmit Clock


  
 Loop Timing—Device receives its clocking from a network source
  
 Internal Module—Device receives its clocking from a network source
  
 Internal Chassis—Device receives its clocking from the configured system clock



 Synchronous Mode


  
 SONET—Synchronous Optical Network
  
 SDH—Synchronous Digital Hierarchy



 Loopback Mode


  
 No Loopback—Disables loopback mode
  
 Line Loopback—Loops the data toward the network; connects the received network signal directly to the transmit network signal line.
  
 Internal Loopback—Loops the data toward the interface of the module; connects the local transmitted signal to the local received signal.




 

4. When you finish setting the line interface parameters, click Save.
