9.4.4 Using a Mesh Node for Local Add/Drop Channel Management
Normally, a multidegree mesh node uses four or eight 40-WXC-C cards and a four- or eight-degree patch
panel. Each of the 40-WXC-C cards uses a 40-MUX-C card to add wavelengths going to the span and a
40-DMX-C or 40-DMX-CE card to drop wavelengths coming in from the span. The 40-MUX-C and
40-DMX-C or 40-DMX-CE cards connect to their respective TXP or MXP cards. In this new local
add/drop channel management configuration, at least one of the directions of a multidegree node can be
used to manage local add/drop traffic. The advantage of this configuration is to consolidate all of the
TXP, MXP, 40-MUX-C, and 40-DMX-C or 40-DMX-CE cards where they are needed for adding or
dropping wavelengths locally. Figure 9-32 shows an example of how to set up a local add/drop
configuration.
By setting up network elements (NE) as shown in the figure, it is possible to connect the transmit ports
of TXP or MXP cards to a 40-MUX-C card and then connect the output of the 40-MUX-C card to an
OPT-BST card, which then connects to a preferred 40-WXC-C card in an NE that has been set up as a
four-degree or eight-degree mesh node. Through software configuration, the wavelengths entering the
preferred 40-WXC-C card can be selectively sent out through a multidegree patch panel and the other
40-WXC-C cards in that NE in any desired outbound direction. In the inbound direction, any of the
wavelengths entering the NE through the 40-WXC-C cards and multidegree patch panel can be
selectively routed to the preferred 40-WXC-C card facing the NE containing an OPT-PRE card and a
