Functional Description
Thus the data rate per subscriber connection (corresponding to one channel) is 256 kbit/s,
whereas the bit rate is 2048 kbit/s. The IOM-2 interface signals are:
IDP0, 1 : 2048 kbit/s
DCLK
FSC1/2* :
: 4096 kHz input
8 kHz input
*Note: FSC1 and FSC2 should be connected together (see figure 12).
Additionally the ISAC-S supplies two programmable strobe signals (SDS1/2), active over the
B-channels of the selected IOM channel (cf. ADF2:DxC2-0).
