Receive X-Bit Number 2: This bit position indicates the receive state of
X2. This bit position is updated each frame.
Receive X-Bit Number 1: This bit position indicates the receive state of
X1. This bit position is updated each frame.
FEBE Transmission Disabled: A one written into this position disables
the transmission of a FEBE when an F-bit or M-bit error or C-bit parity error
occurs.
Transmit DS3 Alarm Indication Signal: A one written into this bit position
causes the DS3F to transmit a DS3 AIS. A one must also be written (if not
already written) into bit 0 (XTX) in this register location in order to satisfy
the definition of DS3 AIS. TXAIS is not effective when input pin XFSI is
active low while operating with a bit-serial terminal side interface.
Enable Transmit DS3 Alarm Indication Signal Automatically: A one
written into this bit position causes the DS3F to transmit DS3 AIS when the
RXOOF bit (Register 00, bit 6) is set to 1.
Transmit DS3 Idle Signal: A one written into this bit position causes the
DS3F to transmit a DS3 idle signal. A one must also be written (if not
already written) into bit 0 (XTX) in this register location, in order to satisfy
the definition of DS3 idle.
mode as specified in Bellcore TR-TSY-000009, and the ANSI T1.107-1995
standard. The M13 operating mode is available for the bit-serial terminal
side interface only. A zero enables the DS3F to operate in the C-bit parity
mode that is specified in the ANSI T1.107-1995 standard. The C-bit oper-
ating mode is available for either a serial or parallel terminal side interface.
Serial Interface Terminal Side: A one configures the DS3F terminal side
to be a serial interface for both receive and transmit. A zero configures the
terminal side to be a nibble interface. The serial interface is operational in
either the M13 or C-bit parity mode. The nibble interface is operational for
the C-bit parity mode only. In the M13 operating mode, the transmit C-bit
interface is disabled and terminal side C-bits are transmitted as user data.
DS3 Transmit-to-Receive Loopback: A one written into this bit position
disables the receive input and causes the transmit output to be looped
back as receive data. Transmit data is provided at the output (D3TD).
Transmit X-Bits: The X-bits may be used to transmit a yellow alarm or as
a low-speed signaling channel. A one written into this bit position causes
the DS3F to transmit a one for both X1 and X2.
