mscHtdsFramerDataInversion
Module: Nortel-MsCarrier-MscPassport-HdlcTransparentMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-HdlcTransparentMIB::mscHtdsFramerDataInversion
OID (numeric): 1.3.6.1.4.1.562.36.2.1.82.2.11.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute determines whether data bits are to be inverted (1 to 0 and 0 to 1) before transmission of frames to the interface. If the value of this attribute is On, the incoming data bits will also be inverted when frames are received from the link before being processed.
This option is typically used in hdlc framing mode when inversion is used to guarantee 1's density.
Note that aborts (in hdlc and interrupting modes) are corrupted when data is inverted.
What is mscHtdsFramerDataInversion?
Controls whether data bits are inverted (1s and 0s swapped) both when transmitting frames to the link and when receiving them, off(0, the default) or on(16); typically used in HDLC framing to guarantee sufficient 1s-density on the line. The DESCRIPTION notes that turning this on corrupts abort-sequence detection in HDLC and interrupting modes, so an admin should weigh that trade-off before enabling it.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.82.2.11.1.2 snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-HdlcTransparentMIB::mscHtdsFramerDataInversion
Get a specific instance (index 1):
