• Redundant serial port information
• Meridian Mail LSL, AML and other TNs.
Note: Although the above items are removed during the conversion
process, the data in the compact flash remains intact with the small
system database.
The CP PM Call Server project introduces a package (410) for enabling and
disabling the Campus Redundancy or High Availability (HA) feature. For
more information, refer to "Appendix A: Upgrading to a High Availability
system" on page 215.
Software determines if the HA package is present in the keycode. If the
package is present, the CP PM call server behaves in the same manner as the
Release 4.5 CP PII or CP PIV (for example, it uses the High Speed Pipe
(HSP) to detect the presence of the other core). If the other core is detected,
then both the cores negotiate to determine which core is active and which core
is the standby.
If the CP PM call server is unable to detect the other core, then it comes up as
a single core system. If the HA package is not present in the keycode, then the
existing call server software is modified to block the HSP connection so that
the CP PM call server does not attempt to detect the presence of the core. In
the absence of the HA package, the CP PM call server runs as a single core
system—even in a system with two cores where the HSP ports on both cores
are connected.
