SNMP MIB Objects
E-93160-A2-GB21-50 January 1997
All four tables are fully supported for the network
interface. Since statistics are not kept for the DTE
Drop/Insert (DSX-1) interface, only the DS1
Configuration table is fully supported. The “statistic”
objects for the DTE Drop/Insert (DSX-1) interface entry
in the DS1 Current, DS1 Interval, and DS1 Total tables
are always zero (null). 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.
Near End Group – “dsx1TimeElapsed” Object(dsx1ConfigEntry 3)
Applies to the network interface only. An error status is
returned if access is attempted for the DTE Drop/Insert
(DSX-1) interface.
Near End Group – “dsx1ValidIntervals” Object(dsx1ConfigEntry 4)
Applies to the network interface only. An error status is
returned if access is attempted for the DTE Drop/Insert
(DSX-1) interface.
Near End Group – “dsx1LineType” Object(dsx1ConfigEntry 5)
This object corresponds to the NET Framing/DTE
Framing configuration options for the T1 interfaces on the
DSU/CSU. Only the following values are supported by
the DSU/CSU.
•dsx1ESF(2) – Indicates ESF framing.
•dsx1D4(2) – Indicates D4 framing.
Near End Group – “dsx1LineCoding” Object(dsx1ConfigEntry 6)
This object corresponds to the NET Coding/DTE
Coding configuration options for the T1 interfaces on the
DSU/CSU. Only the following values are supported by
the DSU/CSU.
•dsx1B8ZS(2) – Indicates B8ZS line coding.
•dsx1AMI(5) – Indicates AMI line coding.
Near End Group – “dsx1SendCode” Object(dsx1ConfigEntry 7)
This object specifies the test patterns/codes being sent
over the network interface. These tests are not supported
on the DTE Drop/Insert (DSX-1) interface. Only the
following values are supported by the DSU/CSU.
•dsx1SendNoCode(1) – Specifies that the interface
is sending normal or looped data. Setting the
interface to this value stops an active “send pattern”
test on the interface. This is the only value
supported by the DTE Drop/Insert (DSX-1)
interface.
•dsx1SendLineCode(2) – Specifies that the network
interface is sending a Remote Loopback (Rlpbk)
LLBUP code. The code is sent for 10 seconds.
•dsx1SendResetCode(4) – Specifies that the network
interface is sending Remote Loopback (Rlpbk)
LLBDN code. The code is sent for 10 seconds.
•dsx1SendQRS(5) – Specifies that the network
interface is sending a QRSS test pattern. The
pattern is sent until the test is halted (i.e., setting to
dsx1SendNoCode).
•dsx1SendOtherTestPattern(8) – Specifies that the
network interface is sending a 1-in-8 test pattern.
The pattern is sent until the test is halted (i.e.,
setting to dsx1SendNoCode).
Near End Group – “dsx1CircuitIdentifier” Object(dsx1ConfigEntry 8)
This object is only supported on the Net T1 Interface.
Near End Group – “dsx1LoopbackConfig”Object (dsx1ConfigEntry 9)
This object specifies the loopback state of the T1
interfaces. Only the following values are supported by the
DSU/CSU.
•dsx1NoLoop(1) – The T1 interface is not in a
loopback state.
•dsx1PayloadLoop(2) – Specifies that a Payload
Loopback (PLB) is active for the network interface
or a Repeater Loopback (RLB) is active for the
DTE Drop/Insert (DSX-1) interface.
