DESCRIPTION
O Receive Framer_n--Time Slot Octet Identifier Output-Bit 0:
These output signals (RxTSb4_n through RxTSb0_n) reflect the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being received
and output to the Terminal Equipment via the Receive Payload Data Output
Interface block associated with Framer_n. The Terminal Equipment should use
the RxTSClk_n clock to sample these five output pins in order to identify the
time-slot being processed by the Receive Section of Framer_n.

O Receive Serial Signaling Output--Receive Framer_n:
These pins can be used to output robbed-bit signaling data extracted from an
incoming DS1 frame, if Framer_n is configured accordingly.
O Receive Framer_n--Time Slot Octet Identifier Output-Bit 1:
These output signals (RxTSb4_n through RxTSb0_n) reflect the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being received
and output to the Terminal Equipment via the Receive Payload Data Output
Interface block associated with Framer_n. The Terminal Equipment should use
the RxTSClk_n clock to sample these five output pins in order to identify the
time-slot being processed by the Receive Section of Framer_n.

O Receive Serial Fractional T1/E1 Input--Receive Framer_n:
These pins can be used to output fractional DS1/E1 payload data extracted from
an inbound DS1/E1 frame, if Framer_n is configured accordingly. In this mode,
terminal equipment will use either rising edge of RxTSClk_n or RxSerClk_n to
clock in fractional DS1/E1 payload data. Please see pin description of
RxTSClk_n for details.
O Receive Framer_n--Time Slot Octet Identifier Output-Bit 2:
These output signals (RxTSb4_n through RxTSb0_n) reflect the five-bit binary
value of the number of Time Slot (in the incoming DS1 frame) being received
and output to the Terminal Equipment via the Receive Payload Data Output
Interface block associated with Framer_n. The Terminal Equipment should use
the RxTSClk_n clock to sample these five output pins in order to identify the

O Receive Framer_n -- Time Slot Identifier Serial Output
If RxTSb1_n pin is configured as RxFrTD_n to output fractional DS1 payload
data from Framer_n, then these pins 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.
