Figure 113 Physical mapping of entities and ICP/CCP
Note: TS25 – TS31 are only applicable for 2048 kbit/s systems.
Each ICP (IS Connection Point) or CCP (CON Connection Point)
represents a 16 kbit/s connection point. They are numbered from 4 to
711. A 16 kbit/s channel is established by connecting two ICPs to each
other. A 32 or 64 kbit/s signalling channel is established by connecting
two or four pairs of consecutive ICPs to each other. The consecutive
ICPs must belong to the same TS or SCH.
