lapbdStatusIndicationIdentifies the lapbdStatusEvent trap which has occurred. This trap is
only generated when global object lapbdTraps is set to value 'enabled'.
Options:
lapbdTeiMacSapNumber: The MAC service access point this trap applies to.
lapbdTeiSapi: TheSAPI number this trap applies to.
lapbdTeiNumber: The TEI number this trap applies to.

RFC1155-SMIDetermines the lower global resource threshold (available buffer space),
that when reached, causes the LAPB/D layer to initiate flow control
(transmission of RNRs). This is a global value that applies across all
lower SAPs (service access points). Thus if resources are low, all links
are affected.
The value set for this object must not exceed the value set for the object
lapbdUpperPoolThreshold.

lapbdUpperPoolThresholdDetermines the upper global resource threshold (available buffer space),
that when reached, causes the LAPB/D layer to cancel flow control. This is
a global value that applies across all lower SAPs (service access points).

lapbdDlSapNumberIdentifies the data link service access point by a unique numerical
value, commonly referred to as the SAPI (service access point identifier).
The SAPI identifies the type of protocol that is supported by this SAP. It
is a LAPD concept which permits the multiplexing of different types of
traffic on the same TEI.
When LAPD service is selected (object lapbdMacSapLapType set to value
'lapd'), and a row is added to the lapbdSapTable, three data link SAPs are
automatically created with following SAPI values: 0, 16, 63
SAPI is not used within LAPB, and as a result when LAPB service is
selected (object lapbdMacSapLapType value 'lapb'), and a row is added to
the lapbdSapTable, only one data link SAP with the value 16 (X.25) is
automatically created.
Options:
0: This SAP is associated with ISDN B- channel call control procedures.
16: This SAP is associated with X.25 over ISDN.
63: This SAP is associated with ISDN management procedures.

to 'modulo 128', which affects the maximum setting that can be made to
this object.
