Homogeneous and Heterogeneous PISN
Each PBX forms a node which is networked in a PISN. In network terminology,
networked PBXs are referred to as a PINX (for Private Integrated services Network
eXchange). A PINX can be set up using the following PBX types:
• ISDN PBX from the Ascotel system family
• ISDN PBX by other manufacturers
• Virtual PBX (private numbering plan from a public network provider)
In a homogeneous network all the PINXs are from the Ascotel system family. If
PBXs by other manufacturers are also used in a network, we talk of a heteroge-
neous network.
