Introduction 147
Model 3120 RAS Administrators’ Reference Guide 11 • Digital Signal Processing (DSP)
Introduction
The access server uses between 48 and 60 digital signal processors (DSPs) to pass digital information. Each
DSP can accept two incoming calls, one on each “instance.” The DSPs are located on chips that contain eight
DSPs each. The access server can access these DSPs in several ways:
• On a per-instance basis—When a DSP is set to AvailableSecondOnly, the access server can disable the sec-
ond instance of a DSP.
• On a per-DSP basis—Each DSP can be set to available, unavailable, or RebootNow in order to enable, dis-
able, disabling or reboot both instances simultaneously

The DSP main window (see figure 60) displays the current state of the DSPs (see “DSP Settings main win-
dow”).
Clicking on the Connection Summary… link takes you to a page that displaying summarized statistics for the
DSPs as a group, and individual statistics for each DSP. For more information about the Connection Summary
window, refer to “DSP Connection Performance” on page 149).
Clicking on the
