40-DMX-C or 40-DMX-CE card. These wavelengths are then sent along to the corresponding TXP/MXP
receive port. The NEs are in separate shelves with separate IP addresses and communicate through DCN
extensions.
The advantage of this configuration is that all of the transponder cards, 40-MUX-C cards, and
40-DMX-C or 40-DMX-CE cards can be located in a single NE, which then communicates with a second
mesh NE containing only 40-WXC-C cards and a multidegree patch panel. Normally, each 40-WXC-C
card in the multidegree node would have its own 40-MUX-C and 40-DMX-C or 40-DMX-CE card and
corresponding TXP/MXP cards. Using this new configuration, the extra 40-MUX-C cards, 40-DMX-C
or 40-DMX-CE cards, and corresponding TXP and MXP cards are eliminated. You now also have a
dedicated NE from which you can send and receive wavelengths to and from any desired direction in the
multidegree node. In addition, the wavelengths and the direction in which they leave the node are
reconfigurable through software and require no manual recabling.
An example of using a mesh node for local add/drop channel management is shown in Figure 9-32.

9.5 DWDM Node Cabling
DWDM node cabling is specified by the Cisco TransportPlanner Internal Connections table. The
following sections provide examples of the cabling that you will typically install for common DWDM
node types.
