The functional block diagram of the ISAC-S TE is shown in figure 8.
The left-hand side of the diagram contains the layer-1 functions, according to CCITT I series
recommendations:
– S-bus transmitter and receiver
– timing recovery and synchronization by means of digital PLL circuitry
– activation/deactivation
– access to S and Q channels
– handling of D channel
– test loops
– send single/continuous AMI pulses (diagnostics).
