MOTOROLA
13.6.4 Example 2: ISDN SOHO PBX with Ports 1, 2, and 3
In this example, port 0 is not used. The port 0 pins are multiplexed with UART0 and in this
example, port 0 is used to connect to an external transceiver to provide an RS232 interface.
Port 1 is programmed in slave mode and an external U (or S/T) transceiver is connected to
port 1. Port 2 and port 3 are used to connect up to four external PCM CODECs.
In the above example, Motorola’s MC14LC5480 CODECs and MC145572 U transceiver
are shown. The U transceiver in this example is connected to port 1 and the FSC1 frame
sync signal is used exclusively for synchronizing the data on the U transceiver’s IDL
interface. CODECs 1 and 2 are connected to delayed frame sync 2, DFSC2, which is the
output of programmable delay 2. Programmable delay 2 generates a delayed frame sync
with reference to FSC1. Similarly CODECs 3 and 4 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 is receiving and transmitting
on the B1 or the B2 time slot (see MC14LC5480 data sheet for further information).
