equivalent AT commands that perform the same configuration
functions.
Network Address
A two-digit decimal address can be assigned to each DSU IV ESP.
This addressing capability makes it possible to perform remote
configuration and testing in point-to-point and multi-drop
networks. Figure 6-1 on page 6-2 shows the menu path used to
change the network address. The factory default setting is
0 .
