CH0, CH1, CH2
In linecard mode one FSC frame is a multiplex of eight IOM-2 channels, each of them
consisting of B1-, B2-, MONITOR-, D- and C/I-channel and MR- and MX-bits.
So in LT-T and LT-S mode one of eight channels on the IOM-2 interface is selected by
CH0-2. These pins must be strapped to VDD or VSS according to table 4.
Table 16 IOM-2 Channel Selection
For DCL = 1.536 MHz one of the IOM-2 channels 0 - 2 can be selected, for DCL = 4.096
MHz any of the eight IOM-2 channels can be selected.
PCMIN, PCMOUT
PCMIN and PCMOUT are receive and transmit lines of the general PCM interface. If
enabled, the B-channels on the IOM-2 interface can flexibly be switched to any timeslot
of the PCM interface.
If the PCM Interface is not used (PCFG:PLD=1), these pins serve as general I/O pins.
FBOUT (FSC/BCL Output)
In LT-T and LT-S mode this pin can be programmed to one of two functions:
• FSC Output (PCFG:FBS=0):
• BCL Output (PCFG:FBS=1):
If the PCM Interface is not used (PCFG:PLD=1), this pin serves as a general I/O pin.
CH2
An FSC clock is output which is derived from the DCL input (SCLK provides a 1.536
MHz output in LT-T mode) divided by 192. This is especially suitable for multiline
applications, where one of several IPACs generates the common FSC.
This pin can output a single bit clock (DCL input divided by 2) equal to the IOM-2 data
rate, especially to serve non IOM-2 compatible peripheral devices on the PCM
interface.
