Transmit Framer_n--Time Slot Octet Identifier Output-Bit 2:
These output signals (TxTSb4_n through TxTSb0_n) reflects the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being accepted
and processed by the Transmit Payload Data Input Interface block associated
with Framer_n.
Terminal Equipment should use the TxTSClk_n clock signal to sample the five
output pins of each channel in order to identify the time-slot being processed
by the Transmit Payload Data Input Interface block of Framer_n.
If TxTSb1_n pin is configured as TxFrTD_n to input fractional DS1 payload
data into Framer_n, the TxTSb2_n pin will serially output the five-bit binary
value of the number of the Time Slot being accepted and processed by the
Transmit Payload Data Input Interface block associated with Framer_n.
Transmit 12.352MHz Clock Output-Transmit Framer_n:
These pins can be used to output 12.352MHz clock derived from OSCClk, if
Framer_n is configured accordingly.
Transmit Framer_n-Time Slot Octet Identifier Output-Bit 3:
These output signals (TxTSb4_n through TxTSb0_n) reflects the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being accepted
and processed by the Transmit Payload Data Input Interface block associated
with Framer_n.
Terminal Equipment should use the TxTSClk_n clock signal to sample the five
output pins of each channel in order to identify the time-slot being processed
by the Transmit Payload Data Input Interface block of Framer_n.
Transmit Overhead Synchronization Pulse--Transmit Framer_n:
These pins can be used to output Overhead Synchronization Pulse that indi-
cate the first bit of each multi-frame, if Framer_n is configured accordingly.
Transmit Framer_n--Time Slot Octet Identifier Output-Bit 4:
These output signals (TxTSb4_n through TxTSb0_n) reflects the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being accepted
and processed by the Transmit Payload Data Input Interface block associated
with Framer_n.
Terminal Equipment should use the TxTSClk_n clock signal to sample the five
output pins of each channel in order to identify the time-slot being processed
by the Transmit Payload Data Input Interface block of Framer_n.
