7.5.1 Introduction
The AUX interface cable is used to connect the AUX interface on the NE40E to a modem to
remotely transmit the configuration data of the NE40E.
The AUX interface cable is an 8-core shielded cable. One end of the cable is an RJ45
connector connected to the AUX interface on the MPU. The other end has DB9 and DB25
connectors, either of which is connected to the serial interface on a computer.

As shown in Figure 7-2 the structure of the AUX interface cable is the same as that of the
console interface cable. Table 7-20 shows the pin assignment on the AUX interface cable.
