2. Principles
All of B-IF4.xx public PHS interface specifications documents have following principles;i)
ii)
iii)
iv)

Interface specification allows to connect Multi-vendor’s SCP Exchanges.
Interface specification allows to connect Multi-operator’s public PHS Networks.
Interface specification allows to use same SCP Exchanges in any public PHS Networks.
B-IF4.xx public PHS Network Interface specifications allow to support all public PHSservices.

3. Network Model and Reference points
Network Model and Reference Points of IF4 which uses INAP interfaces refers to the PHS-MoU
B-NW1.00-02-TS.
4. Protocol Architecture Model on IF4
The concepts, terminology, overview and description, of IF4 layer 1 to 7 are conformed to ITU-T
Recommendations. The other issues also meet to ITU-T Recommendations and they are specified in
B-IF4 Series documents. The specifications of MTP layer refers to the PHS-MoU IF3.11 to IF3.17.
Figure 4-1 / B-IF4.00 shows the protocol architecture model on IF4.
