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-

•
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
revisions 1 or less), DSPs are rebooted on a per-chip basis. (For information
on displaying the PCB revision number, refer to
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.
