3.3 Expanding PS Capacity
The maximum number of Wireless PS stations has been expanded from 168 to 250 when an Integrated type
system is being used. Previously, each PS line reduced the capacity of CM10 by three ports [One port for CM1C
and two ports for CM10 (one Virtual Trunk and one Virtual Station)]. With a CPXX-C card and 1900 Series
Release 2 software, each PS line reduces the capacity of CM10 by only two...

The table below shows the example of the system capacity on NEAX2000 IVS.
Note:When the 168 PSs have been provided in the system, and more PSs are required, the all existing PSs’
office data must be cleared by the CM1C individually and re-entered. By this means, up to 250 PSs can
be provided.
For example, if 50 PSs will be added, 100 existing PSs’ office data must be cleared and re-entered.
