### Description

docsQosPHSMask OBJECT-TYPE
SYNTAX OCTET STRING(SIZE(0..32))
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Payload header suppression mask defines the
bit mask which used in combination with the
docsQosPHSField defines which bytes in header
must be suppressed/restored by the sending or
receiving device.
Each bit of this bit mask corresponds to a byte
in the docsQosPHSField, with the least
significant bit corresponding to first byte of
the docsQosPHSField.
Each bit of the bit mask specifies whether of
not the corresponding byte should be suppressed
in the packet. A bit value of '1' indicates that
the byte should be suppressed by the sending
device and restored by the receiving device.
A bit value of '0' indicates that
the byte should not be suppressed by the sending
device or restored by the receiving device.
If the bit mask does not contain a bit for each
byte in the docsQosPHSField then the bit mask is
extended with bit values of '1' to be the
necessary length."
