• Description: ISDN SubscribernAccess Controller
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

X1 and FSC2 are driven between the first and the second falling edge of the DCL signal. They
are always not connected between the first rising and the first falling edge as well as the
second falling and the first rising edge.
Note: This feature should not be used if a PSB 2186 ISAC-S TE is considered to replace the

In IOM-2 terminal mode (SPCR:SPM=0) the IOM interface can be switched off for external
devices via IOF bit in ADF1 register. If IOF=1, the interface is switched off i.e. DCL, FSC1,
IDP0/1 and BCL are high impedance.
