Paradyne Hotwire M/SDSL and HDSL2 Termination Units, 8747, 8777, 8779 manual LinkUp and linkDown

Standards Compliance for SNMP Traps

linkUp and linkDown

The link SNMP traps are:

HlinkUp – The unit recognizes that one of the communication interfaces is operational.

HlinkDown – The unit recognizes that one of the communication interfaces is not operational.

The network and synchronous port interfaces (physical sublayer) are represented by an entry in the MIB-II interfaces table and supported by the DS1 MIB.

The following list describes the conditions that define linkUp and linkDown:

linkUp/Down variable bindings

HifIndex (RFC 1573)

This object provides the index into the ifTable and potentially into tables in other MIBs. The ifIndexes supported are:

–3–10 DSL Network Interface

–15–22 DSX-1 or G.703 Port

–39–46 EOC Management Link

HifAdminStatus (RFC 1573)

This object specifies the operational state of the interface:

–up(1)

The interface is enabled.

–down(2)

The interface is disabled.

HifOperStatus (RFC 1573)

This object specifies the operational state of the interface:

–up(1)

DSL Port: DSL link is established and no alarms exist.

DSX-1 or G.703 Port: No alarm conditions exist.

EOC: Based on the state of the link layer protocol.

–down(2)

DSL Port: DSL link is not established or alarms exist.

DSX-1 or G.703 Port: Alarm condition exists.

EOC: Based on the state of the link layer protocol.

–testing(3)

DSL, DSX-1 or G.703 Port: A test is active on the port.

–dormant(5)

DSL Port: DSL link is negotiating.
