• RFC 1213 MIB II. The Internet-standard MIB for network management of TCP/IP-based internets. It defines
objects common to all devices that support SNMP. This includes objects related to generic configuration such
as the device's name (sysName), objects related to the transport protocols (IP, TCP, ICMP, etc.), and a descrip-
tion of the chassis' interface ports (data ports as well as HDSL ports).
• pgmibhd.mib (Common MIB). An enterprise MIB (that is, unique to ADC products) that defines the top-level
branch structure for all ADC products including the WorldDSL product line.
• pgetsi.mib (ETSI Interface MIB). Enterprise MIB containing management objects for the shelf common equip-
ment (chassis and EMU-830) and DSL circuit elements (LTUs/STU-Cs, NTUs/STU-Rs, doublers), excluding
DSL performance related objects which are contained in the DSL MIB. Examples include the EMU-830 LED sta-
tus (emuLedStatus), an LTU/STU-C V.35 port data rate (ltuDataPrtTimeSlots), and PTM managed items.
• pghdsl.mib (DSL MIB). Enterprise MIB containing objects related to the
performance of the DSL links, such as 15-minute and 24-hour performance history.
• pgagtmib.mib (SNMP Agent MIB). MIB containing management objects to control and configure the operation
of the IP and SNMP parameters. Examples include the EMU IP address, boot and image mode, and trap
receiver setup.
• pgetsitr.mib (ETSI SNMP Trap MIB). MIB containing a subset of the RFC 1215 common traps as well as ADC
enterprise traps (see
T
RAPS
Traps are autonomous, interrupt-driven messages sent from a managed node (shelf) to a management station to
indicate the occurrence of an extraordinary event (such as alarms or a link going down) or a configuration change
(such as changes in alarm severity settings, circuit IDs, or loopback modes). When an event occurs, the shelf sends
a trap to the management station, which polls the shelf to determine the nature of the event. Circuit Name is also
included in the trap.
A managed node (shelf) can be configured to send traps to up to three trap receivers (that is, management stations).
The WorldDSL traps are listed in

Table 1-2. WorldDSL Traps
MIB II standard trap indicating that the EMU-830 has come on-line.
MIB II standard trap indicating that the agent received an SNMP message with
an improper community string. For example, an SNMP-managed device
assigned to the community "ETSI" receives a message for a device in the
"HGIS" community.
MIB II standard trap indicating a loss of signal condition at one of the
transmission interfaces (E1 or DSL).
ADC enterprise trap sent at the occurrence of an alarm condition on an DSL
circuit if that alarm is of a greater severity than any existing alarms on the
same circuit. Separate trap messages are sent for each DSL circuit in
the shelf.
