Figure 1-14 shows how the module front panel ports are mapped and labeled. The multimode module is
mapped and labeled the same as the single-mode module.

Table 1-2 details the single-mode and multimode front panel Protection A mapping. It shows how two
DWDM receive inputs (client working and protect) provide one output signal to the customer client
equipment, using the module combiner function.
Table 1-3 details the single-mode and multimode front panel Protection A mapping. It shows how the
module splits a single receive input from the equipment into two DWDM output signals (working and
protect) to the TXP client port.
