The PT7A6632 HDLC Controller is applied between an exter-nal memory and T1/E1 trunk interface to perform data trans-mission and reception. See Figure 1. Its signal attributes are shown in Figure 4.
PT7A6632 reads the data to be transmitted from the external memory in 8-bit parallel way, formats them and adapts data rate, then transmits the data to the T1/E1 trunk interface.
PT7A6632 receives serial data from the T1/E1 trunk interface,deformats them and adapts data rate, then stores the data into the external memory.
The channel operation modes are set up in the external memory by CPU. PT7A6632 reads the commands from the external memory and process data channel by channel, totally 64 chan-nels (32 for transmission and 32 for receive). Each channel mode can be set up in external memory independently by CPU.
