Application Examples
Figure 13-37. ISDN SOHO PABX Example
In the above example, Motorola’s MC14LC5480 CODECs and MC145574 S/T transceiver
are shown. The S/T transceiver in this example is connected to port 0 and the FSC0 frame
sync signal is used exclusively for synchronizing the data on the transceiver’s IDL
interface. CODECs 1 and 2 are connected to frame sync 1, FSC1. CODECs 3 and 4 are
connected to DFSC2 which is the output of programmable delay 2. Programmable delay 2
generates a delayed frame sync with reference to FSC1. Similarly CODECs 5 and 6 are
connected to DFSC3 which is the output of programmable delay 3. Programmable delay 3
generates a delayed frame sync also with reference to FSC1. The MC14LC5480 CODECs,
when in IDL mode, may be programmed using the FSR pin, to select whether the CODEC
