TxA
Transmit A Output
. Unipolar output that can be used in conjunction with TxB and
external line driver circuitry to generate the bipolar DS1 signal.
2
3
TxB
Transmit B Output.
Unipolar output that can be used in conjunction with TxA and
external line driver circuitry to generate the bipolar DS1 signal.

DSTo
Data ST-BUS Output.
A 2048 kbit/s serial output stream which contains the 24
PCM or data channels received from the DS1 line.

NC
No Connection.
5

RxA
Receive A Complementary Input.
Accepts a unipolar split phase signal decoded
externally from the received DS1 bipolar signal. This input, in conjunction with RxB,
detects bipolar violations in the received signal.
6
10
RxB
Receive B Complementary Input.
Accepts a unipolar split phase signal decoded
externally from the received DS1 bipolar signal. This input, in conjunction with RxA,
detects bipolar violations in the received signal.
7
11
RxD
Receive Data Input.
Unipolar RZ data signal decoded from the received DS1
signal. Generally the signals input at RxA and RxB are combined externally with a
NAND gate and the resulting composite signal is input at this pin.
8
13
CSTi1
Control ST-BUS Input #1.
A 2048 kbit/s serial control stream which carries 24 per-
channel control words.
9
14
TxFDL
Transmit Facility Data Link (Input).
A 4 kHz serial input stream that is multiplexed
into the FDL position in the ESF mode, or the F
s
pattern when in SLC-96 mode. It is
clocked in on the rising edge of TxFDLClk.

16
TxFDLClk
Transmit Facility Data Link Clock (Output).
A 4 kHz clock used to clock in the FDL
data.
