error rates.
Generates a BIP-2 error over the Lower-Order Path layer.
Bits in the V5 byte are toggled to create an error.
Only available when a LP mapping is selected.
Generates a Remote Error Indicator over the Lower-Order
Path layer. An LP-REI is a count of LP-BIP 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 LPOH 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 LP mapping is selected.
Generates bit errors.
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 error rates.
Generates a Tandem Connection Incoming Error Count over
the Higher-Order Path layer. A TC-IEC is a count of B3
errors received by TCM equipment at the far end. Bits 1-4 of
the N1 byte are the IEC bits.
Only appears when the
configured for "HP Enable".
Generates a Tandem Connection Remote Error Indicator
over the Higher-Order Path layer between TCM equipment.
Bit 5 of the N1 byte is used for this error.
Only appears when the
configured for "HP Enable".
Generates a Tandem Connection Outgoing Error Indicator
over the Higher-Order Path layer between TCM equipment.
