DATA SHEET
TranSwitch Test Pin: Leave open.
Overhead Enable: An active high signal that enables
an overhead error to be introduced into the overhead
bit in the next 85th group by placing a low on the
FORCEOE pin.
DS3 Received X-Bit 1: An output indication of the
state of the first X-bit received in the DS3 frame
(bit 1). The indication is active until the next X1 state
is detected.
DS3 Received X-Bit 2: An output indication of the
state of the second X-bit received in the DS3 frame
(bit 680). The indication is active until the next X2
state is detected.
C-Bit Transmit Data: Serial interface for transmit-
ting the following C-bits in the C-bit parity mode:
C2, C4, C5, C6, C13, C14, C15, C16, C17, C18,
C19, C20, and C21. C-bit data is clocked into the
DS3F on rising edges of the C-bit gapped clock
(CXCK). A C-bit must be transmitted as a one if not
used.
C-Bit Transmit Data Link Clock: A gapped clock
provided for clocking the three data link bits (C13,
C14, and C15). In Extended mode, a control bit is
available to convert the three cycles into a single
envelope pulse (see Figure 10).
C-Bit Transmit Framing Pulse: Identifies the loca-
tion of the first C-bit in the DS3 frame.
C-Bit Transmit Clock: A gapped clock which
clocks the external C-bit serial data into the DS3F
on rising edges.
