Transmit C-Bit Clock: A gapped clock signal is provided
for clocking in selected transmit C-bit data (CDT). Data is
clocked into the M13E on positive transitions.
Transmit C-Bit Data: The transmit gapped clock (CCKT)
is provided for clocking in the following C-bits: C2, C3
(depending on the setting of bit 7 of register 19H,
C3CLKI), C4, C5, C6, C13, C14, C15, C16, C17, C18,
C19, C20, and C21. An unused C-bit should be transmit-
ted as a one.
Transmit C-Bit Framing Pulse: This positive framing
pulse occurs prior to the C2 bit.
Transmit Data Link Indication: A positive pulse that
identifies the location of the three data link C-bits (C13,
C14, and C15). The transmit C-bit clock (CCKT) may be
and-gated with this signal to provide a gapped data link
clock signal. This signal is enabled by placing a high on
the signal lead labeled DLEN.
Outputs Disable: A low causes all M13E outputs and
bidirectional signal leads to be set to a high impedance
state for test purposes except the CDCCR and CDCCT
pins. The CDCCR and CDCCT pins can be tri-stated by
applying a low to the DLEN pin. This lead is provided with
an internal pull-up resistor.
Data Link Enable: Normally left open. A high enables
the transmit and receive data link indication signals,
CDCCT and CDCCR. The data link indication signals
identify the location of the three data link C-bits (C13,
C14, and C15).
TranSwitch Test Pin: Leave open.
