Access Server Administrators’ Reference Guide 11 • Digital Signal Processing (DSP)

Introduction

The access server uses between 12 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

Note On boards manufactured before October 31, 2001 (printed circuit board revisions 1 or less), DSPs are rebooted on a per-chip basis. (For information on displaying the PCB revision number, refer to “PCB Revision (boxManu- facturePcbRevision)” on page 233.) When a DSP is selected to be rebooted, not only will that DSP be rebooted, but so will the other seven DSPs that are located on the same chip. For example, if DSP1 is set to reboot, DSPs 2–8 will also reboot.

Click on DSP under the Configuration Menu to display the DSP Settings main window.

The DSP main window (see figure 59) 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 147).

Clicking on the DSP Index link displays detailed information about the DSP (see section “DSP information window” on page 151.
