DS1/E1 MIB (RFC 1406)

The ªds1º object defined by RFC 1406 is supported for both the network and G.703 DTE 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 G.703 DTE interface, only the DS1 Configuration table is fully supported. The ªstatisticº objects for the G.703 DTE 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 NTU.

Near End Group ± ªdsx1TimeElapsedº Object (dsx1ConfigEntry 3)

Applies to the network interface only. An error status is returned if access is attempted for the G.703 DTE interface.

Near End Group ± ªdsx1ValidIntervalsº Object (dsx1ConfigEntry 4)

Applies to the network interface only. An error status is returned if access is attempted for the G.703 DTE interface.

Near End Group ± ªdsx1LineTypeº Object (dsx1ConfigEntry 5)

This object corresponds to the NET Framing/DTE Framing configuration options for the E1 interfaces on the E1 NTU. Only the following values are supported by the E1 NTU.

•dsx1E1(4) ± Indicates non-CRC-4 framing.

•dsx1E1-CRC(5) ± Indicates CRC-4 framing.

Near End Group ± ªdsx1LineCodingº Object (dsx1ConfigEntry 6)

This object corresponds to the DTE Coding configuration option on the E1 NTU. Only the following values are supported by the E1 NTU.

•dsx1HDB3(3) ± Indicates HDB3 line coding.

•dsx1AMI(5) ± Indicates AMI line coding (for DTE only, not available for NET).

Near End Group ± ªdsx1SendCodeº Object (dsx1ConfigEntry 7)

This object specifies the test patterns/codes being sent over the network interface. These tests are not supported on the G.703 DTE interface. Only the following values are supported by the E1 NTU.

•dsx1SendNoCode(1) ± Specifies that the interface is sending normal or looped data. Setting the interface to this value stops an active ªsend patternº test on the interface. This is the only value supported by the G.703 DTE interface.

•dsx1SendOtherTestPattern(8) ± Specifies that the network interface is sending a 1-in-8 or a 32767 test pattern. This value is read-only. An attempt to write this value returns a badValue response.

Near End Group ± ªdsx1CircuitIdentifierº Object (dsx1ConfigEntry 8)

This object is only supported on the network interface.
