3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
2.2.6.5
The four User Cell Filter – Pattern Registers permit the user to specify the Header Byte Pattern for the
Transmit User Cell Filter. There are four User Cell Filter – Pattern Registers (one for each of the four (4)
header bytes, within an ATM cell). The bit-format of these “User Cell Filter – Pattern Registers” is presented
below.
Transmit ATM Filter # 0, # 1, # 2, # 3 Pattern – Header Byte 1 (Address = 0xNF44, 0xNF54, 0xNF64,
0xNF74)
Transmit ATM Filter # 0, # 1, # 2, # 3 Pattern – Header Byte 2 (Address = 0xNF45, 0xNF55, 0xNF65,
0xNF75)
Transmit ATM Filter # 0, # 1, # 2, # 3 Pattern – Header Byte 3 (Address = 0xNF46, 0xNF56, 0xNF66,
0xNF76)
Transmit ATM Filter # 0, # 1, # 2, # 3 Pattern – Header Byte 4 (Address = 0xNF47, 0xNF57, 0xNF67,
0xNF77)
