ACCULINK 3172 and 3174 E1 DSU/CSU
DS1/E1 MIB (RFC 1406)
The "ds1" object defined by RFC 1406 is supported for
both the network and DTE Drop/Insert interfaces. The
DS1 Near End Group and DS1 Fractional Group are
supported for both interfaces. The DS1 Far End Group is
not supported.
Near End Group, DS1/E1 MIB
The DS1 Near End Group consists of the following
four tables:
DS1 Configuration
DS1 Current
DS1 Interval
DS1 Total
All four tables are fully supported for the network
interface. Since statistics are not kept for the DTE
Drop/Insert interface, only the DS1 Configuration table is
fully supported. The "statistic" objects for the DTE
Drop/Insert 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
E1 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
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
interface.
E-8
Near End Group – "dsx1LineType" Object
(dsx1ConfigEntry 5)
This object corresponds to the NET Framing/DTE
Framing configuration options for the E1 interfaces on the
E1 DSU/CSU. Only the following values are supported by
the E1 DSU/CSU.
dsx1E1(4) – Indicates non-CRC-4 framing.
dsx1E1-CRC(5) – Indicates CRC-4 framing.
Near End Group – "dsx1LineCoding" Object
(dsx1ConfigEntry 6)
This object corresponds to the DTE Coding
configuration option on the E1 DSU/CSU. Only the
following values are supported by the E1 DSU/CSU.
dsx1HDB3(3) – Indicates HDB3 line coding.
dsx1AMI(5) – Indicates AMI line coding (for DTE
only, not available for NET).
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 interface. Only the following
values are supported by the E1 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 interface.
dsx1SendOtherTestPattern(8) – Specifies that the
network interface is sending a 1-in-8 test pattern.
This value is read-only. An attempt to write this
value returns a badValue response.
