3-2 Getting Started

This chapter has three parts:

• System Requirements for Software Upgrades

• Configuring and Operating the Modem 

• Other Call Establishment Methods

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.

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.

The DTE manual should tell you what data format—asynchronous or synchronous—
it uses. Most PC applications use an asynchronous data format.

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.
