### Description

```asn1
sonetLineBIPs OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of Line BIP-24 (Bit Interleaved Parity) errors
that have been detected since the last time the port has
been reset. The calculated BIP-24 code is based on the line
overhead and synchronous payload envelope (SPE) of the STS-
3c stream. The line BIP-24 code is a bit interleaved parity
calculation using even parity. The calculated code is
compared with the BIP-24 code extracted from the B2 bytes of
the following frame. Differences indicate that a line layer
bit error has occurred."
