Interface Naming Conventions
Figure 2-6 OADM Module Interfaces
Filter Interfaces
The filter interface connects to a wavepatch interface on either a transponder line card or a 10-Gbps ITU
trunk card. Each filter interface corresponds to an individual wavelength filter. The filter interface
connects a wavepatch interface to a wdm interface on the same OADM module.
The naming convention for filter interfaces is as follows:
filter slot/subcard/port
Each OADM module has four filter interfaces.
Oscfilter Interfaces
The OADM modules can support an optional OSC with an oscfilter interface. This interface connects to
the wave interface on an OSC card.
The naming convention for the OSC interface on an OADM module is as follows:
oscfilter slot/subcard
Wdm Interfaces
The wdm interface is the interface on the OADM module that receives the DWDM signal containing
wavelengths to be dropped, or transmits the DWDM signal with added wavelengths. It represent the pairs
of fibers (Tx and Rx) on the front panel of an OADM module. The wdm interface connects either to a
wdm interface on another network node, or to a thru interface on an OADM module on a different chassis
in the same network node.
The naming convention for wdm interfaces is as follows:
wdm slot/subcard
