Transmit Serial Data Input (TxSERn)/Transmit Positive Digital
Input (TxPOSn):
The exact function of these pins depends on the mode of operation
selected, as described below.
DS1/E1 Mode - TxSERn
These pins function as the transmit serial data input on the system
side interface, which are latched on the rising edge of the TxSER-
CLKn pin. Any payload data applied to this pin will be inserted into an
outbound DS1/E1 frame and output to the line. In DS1 mode, the
framing alignment bits, facility data link bits, CRC-6 bits, and signaling
information can also be inserted from this input pin if configured
appropriately. In E1 mode, all data intended to be transported via
Time Slots 1 through 15 and Time slots 17 through 31 must be
applied to this input pin. Data intended for Time Slots 0 and 16 can
also be applied to this input pin If configured accordingly.
DS1 or E1 High-Speed Multiplexed Mode* - TxSERn
In this mode, these pins are used as the high-speed multiplexed data
input pin on the system side. High-speed multiplexed data of chan-
nels 0-3 must be applied to TxSER0 in a byte or bit-interleaved way.
The framer latches in the multiplexed data on TxSER0 using TxM-
SYNC/TxINCLK and demultiplexes this data into 4 serial streams.
The LIU block will then output the data to the line interface using
TxSERCLKn.
DS1 or E1 Framer Bypass Mode - TxPOSn
In this mode, TxSERn is used for the positive digital input pin
(TxPOSn) to the LIU.

1.
*High-speed multiplexed modes include (For T1/E1)
16.384MHz HMVIP, H.100, Bit-multiplexed modes, and (For
T1 only) 12.352MHz Bit-multiplexed mode.
2.
In DS1 high-speed modes, the DS-0 data is mapped into an
E1 frame by ignoring every fourth time slot (don’t care).
3.
These 8 pins are internally pulled “High” for each channel.
