Tx FIFO Reset Enable:
automatic recovery from Tx FIFO
underflow/overflow enabled
Reset Tx FIFO:
Transition from “0” to “1” causes a
reset of the Tx FIFO. Control bit is
reset to "0" upon completion of
operation.
Disable Tx Line AIS Detection:
detection of AIS-L at Tx Terminal
Port disabled. If bits 6, 7, and 8 of
the Byte are indeterminate, then
DISTLAIS must be set to "1" to
inhibit the TAIS-L Alarm.
Loop Back AIS Generation
Enable: generate AIS in Tx Line
Port Data during Tx-Rx Loop
Loop Back AIS Select:
AIS-L generated (all Bytes = "1"
except the 9 SOH Bytes)
Tx Frame Reference Input
Enable: failure at TFRI pin included
in LOTR equation
Datacom Frame Reference Input
Enable: failure at DFRI/DFRI pin
included in LOTR equation
Tx Terminal Datacom Data Delay:
delay time from Rising Edge of
TSPEI/O to sampling of data at Tx
Terminal Port is:
Serial Datacom - 4½ bit times to
MSB of serial data (See Figure 62)
Parallel Datacom - 3 clock times
(See Figures
Bit Equal to "1"
