PCS Levels

Each item of IP Office hardware has a Product Change Status (PCS) level. This is usually included on the label on the hardware prefix with PCS.

The PCS level is increased each time a significant change is made to the components of that piece of hardware. For example the PCS level may increased when a component is replaced by one from a different supplier.

Normally changes to a PCS level are not important and items of the same hardware but with different PCS levels are still identical in operation and can be interchanged. However, there are some exceptions as listed below.
