SNMP MIB Objects
E-133160-A2-GB22-10 December 1996
Output Signal Table – “rs232OutSigName”
(rs232OutSigEntry 2)
This object contains the identification of a hardware
output signal. Only the following values are supported by
the DSU/CSU.
• cts(2) – Clear-To-Send
• dsr(3) – Data Set Ready
Output Signal Table – “rs232OutSigState”
(rs232OutSigEntry 3)
This
object contains the current signal state. Only the
following values are supported by the DSU/CSU.
•
on(2) – The signal is asserted.
• off(3) – The signal is not asserted.
Output Signal Table –
“rs232OutSigChanges”
(rs232OutSigEntry 4)
This object is not supported by the T1 DSU/CSU.
Generic-Interface MIB
Extensions (RFC 1229)
The generic interface MIB is an experimental MIB that
provides extensions to the generic interface group defined
in MIB II. This MIB describes three tables:
• Generic Interface Extension Table
• Generic Interface Test Table
•
Generic Receive Address T
able
Only the generic interface test table is supported by the
T1 DSU/CSU. This table is supported for Network T1
interface and the synchronous DCE data ports only. It is
not supported for the DTE Drop/Insert T1 interface, the
COM port, and MODEM port.
Generic Interface Test Table, Generic
Interface MIB
The
test table is used to provide access to additional
tests (loopbacks and pattern tests) that are not provided for
in the interfaces group of MIB II. The following sections
provide clarification for objects contained in the Near End
Group when it is not clear how the object definition in the
DS1/E1 MIB is related to the DSU/CSU.
Generic Interface Test Table –
“ifExtnsTestType” Object
(ifExtnsTestEntry 4)
This
object is a control variable used to start and stop
operator-initiated tests on the interface. It provides the
capability to:
• Start/stop the Monitor QRSS test pattern on the
network T1 interface.
• Start/stop the Send QRSS/511 test pattern on a
synchronous DCE data port.
• Start sending a V.54/FT1 UP/DOWN code to the
remote unit for a synchronous DCE data port.
• Start/stop the Monitor QRSS/511 test pattern on a
synchronous DCE data port.
• Start/stop the DCLB/DTLB loopback test on a
synchronous DCE data port.
The following object identifiers are used to control the
tests on the interface. The “noT
est” and
“testFullDuplexLoopBack” object identifiers are defined
in the generic interface MIB, the other object identifiers
are defined here.
• noT
est – Stops the test in progress on the interface.
•
testFullDuplexLoopBack – Initiates a DCLB on the
interface. Only supported for the data ports.
• testLoopDTLB – Initiates a DTLB on the interface.
Only supported for the data ports.
