B3 byte are toggled to create an error.
This type of simulation allows an NE (in this case, the
downstream equipment) to be tested to verify if (1) it can
detect incoming errors, and (2) then conduct performance
monitoring such as error counts and rates.
Generates a Remote Error Indicator over the Path layer. An
REI-P is a count of B3 errors received at the far end.
When the system transmits this error, it simulates an NE
sending an error count back to the source of its incoming
SONET signal. The system uses the G1 byte of the Path OH
to transmit the error count. This type of simulation allows an
NE (in this case, the upstream equipment) to be tested to
verify if (1) it can detect incoming remote errors, and (2) then
conduct performance monitoring such as error counts and
error rates.
(This type of error was formerly called a Path Far End Block
Error - FEBE-P.)
Generates a BIP-2 error over the VT layer. Bits in the V5
byte are toggled to create an error.
Only available when a VT mapping is selected.
Generates a Remote Error Indicator over the VT layer. An
REI-V is a count of BIP-V errors received at the far end.
When the system transmits this error, it simulates an NE
sending an error count back to the source of its incoming
SDH signal. The system uses the V5 byte of the VTOH to
transmit the error count. This type of simulation allows an NE
(in this case, the upstream equipment) to be tested to verify if
(1) it can detect incoming remote errors, and (2) then
conduct performance monitoring such as error counts and
error rates.
Only available when a VT mapping is selected.
Generates bit errors.
