Datasheet
This counter increments each time a BIP error event in the Low Order Path section is detected. To
access the count, the microprocessor must provide a Write command to the MSB address bit of
register x6H at least 3 byte clock periods (0.5us in STM-0) before the two Read commands. The
Write command clears the counter after buffering it.

15H;

9H=Bits<15:8>,
x
8H=Bits<7:0> (Byte access only)
This counter increments each frame in which the receive V5 REI bit is set. To access the count, the
microprocessor must provide a Write command to the MSB address bit of register x9H at least
three byte clock periods (0.5us in STM-0) before the two Read commands. The Write command
clears the counter after buffering it.

K4_STA
K4 Status (

AH)
x
=1
15H
The K4 byte provides an Enhanced RDI that can be retrieved via a read of this register. This
register is updated only if there is a change in the V5 RDI bit and the tributary source supports K4
ERDI.
8.6.5
V5_STA
V5 Status Register (
x
BH)
x
=1
15H
The V5 status register is provided for raw access to the received V5 byte (see Figure 4). There is no
alarm or INT generation directly associated with this register. The value in this register changes
every multiframe (500uS).
