REI Enable: A 1 enables the local B3 parity error count or the remote B3
parity error count to be inserted as the REI value. A 0 written into this posi-
tion permits the microprocessor to control the value of the REI count.
The logic diagram for sending REI for all conditions is given below. The +
symbol represents an OR function, while & represents an AND function.
Control bit states are given by the = sign.
(ISTAn and PAISn) to control alarm generation instead of AIS in the E1
byte. A 0 causes alarm generation to be based on E1AIS from the Drop
bus.
Reserved: Must be set to zero when register is written.
send SDH/SONET DS3 AIS or E3 AIS automatically when a transmit line
clock failure is detected.
The logic diagram for transmitting a line AIS is given below. The + symbol
represents an OR function, while & represents an AND function. Control bit
states are given by the = sign.
Transmit Loss Of Signal (TPOSn/TNEGn) AIS Enable: A 1 enables the
channel to send DS3 or E3 AIS automatically when a transmit line signal
failure is detected, as shown in the logic diagram above.
Clear On Read: A 0 enables all performance counters for that channel to
become non- saturating with roll over capability. The contents of the
counter are not affected by a read cycle. A 1 causes the performance
counters to become saturating counters, which clear on a read cycle.
Reserved: Must be set to zero when register is written.
