wanInterfaceEntryLineCoding 1.3.6.1.4.1.52.4.1.2.7.1.1.4.1.8

This object describes the variety of Zero Code suppression on this interface. For an interface on a Ds1 Port, the valid values depend on the value of the Ds1ConfigLineCode object. If that object is set to ds1xB8ZS, then this object can be set to none, JBZS, or InvHDLC. If the value of Ds1ConfigLineCode is set to ds1xAMI, then this object can only be set to JBZS, or InvHDLC. For an interface on a Synchronous Port, the valid values are none or InvHDLC. JBZS refers to Jammed Bit Zero suppression, which forces a 1 bit every 8 bit periods. InvHDLC refers to inverting the HDLC data for the interface. None refers to a mode in which some other means, such as with the Ds1ConfigLineCode object set to dsx1B8ZS, is used to insure pulse density requirements.
