Introduction
This chapter has three parts:
• System Requirements for Software Upgrades
• Configuring and Operating the Modem
• Other Call Establishment Methods
System Requirements for Software Upgrades
This section explains the prerequisites for an upgrade to 7.9 software. This section
does not apply to new units with 7.8 or higher software installed.
A modem can be upgraded to Release 7.9 software only if it has Release 7.0, 7.5, 7.6,
or 7.7 software.
Configuring and Operating the Modem
You can configure and operate the modem in several ways:
• From the modem front panel
• From a Network Management System (NMS)
• From the modem AT Automatic Calling Unit (ACU), if it is attached to an
asynchronous “dumb” terminal—a terminal without software—or to a PC
running an asynchronous communications software package
Each of these is described in the sections that follow.
If You Are Unsure of Your DTE’s Data Format...
The DTE manual should tell you what data format—asynchronous or synchronous—
it uses. Most PC applications use an asynchronous data format.
Using the Front Panel
You can configure and operate all modem functions using the front panel’s:
• Light-emitting diodes (LEDs)
• Liquid crystal display (LCD)
• Configuration menus
• Control keys
Figures 3-1 and 3-2 show the stand-alone modem front panel. Figure 3-3 shows the
enclosure card front panel. Note the LCD, LEDs, and control keys.
NOTE: Information specific to enclosure card modems is covered in the addendum,
326X Series Modem Cards, shipped with the modem backplane.
