Access to CM
DIO = 0
Transparent Switching (i.e. the MUSAC works exactly like a MTSC)
D9
Validity bit: A logical 0 enables the programmed connection,
a logical 1 tristates the outputs
D8 … D0
Logical line and time-slot number of the inputs
IA7… IA0
Logical line and time-slot number of the outputs
D9 – D0
Is written to the CM address IA7 – IA0
DIO = 1
Conference Switching or Multipoint Switching Mode
D9
Validity bit: A logical 0 enables the programmed connection,
a logical 1 tristates the outputs
D8 … D6
Logical 0
D5 … D0
Conference control address
IA7 … IA0
Logical line and time-slot number of the outputs
D9 – D0
Is written to the CM address IA7 – IA0. D5 – D0 contain the address which points
to the appropriate CCM location.
D8 – D0 and IA7 – IA0 contain the information for the logical line and time-slot numbers of the
programmed connection, D8 – D0 for the inputs, IA7 – IA0 for the outputs.
Table 10
shows the
programming of these bits for standard configuration,
table 11 and 12
for the primary access
configuration.
