TP3155 Time Slot Assignment Circuit
General Description
The TP3155 is a monolithic CMOS logic circuit designed to
generate transmit and receive frame synchronization pulses
for up to 8 COMBO
pulse may be independently assigned to a time slot in a
frame of up to 32 time slots Assignments are controlled by
loading in an 8-bit word via a simple serial interface port
This control interface is compatible with that used on the
TP3020 TP3021 and 2910 2911 CODECs enabling an
easy upgrade to COMBO CODEC Filters to be made
