ACCULINK 3350 E1 NTU
Interface Group – "ifAdminStatus" Object
(ifEntry 7)
This object specifies the desired state (configuration)
of the interface. This object is supported only for the
COM port. It provides the ability to switch between using
the port for SNMP or ASCII operations. The value of this
object will not affect the state of any of the interfaces on
the E1 NTU other than the COM port. Only the following
values are supported by the E1 NTU:
up(1) – The SNMP management link is active on
the COM port.
testing(3) – The SNMP management link is inactive
on the COM port; the COM port can be used for
proprietary ASCII functions.
Interface Group – "ifOperStatus" Object
(ifEntry 8)
This object specifies the current operational state of the
interface. The value of this object for each interface is
defined as follows:
Network E1: The interface is up(1) when no
alarm conditions exist.
The interface is down(2) when an
alarm condition is active.
The interface is testing(3) when a
test is active on the interface.
DTE E1: The interface is up(1) when no
alarm conditions exist and the
interface is enabled.
The interface is down(2) when an
alarm condition is active or the
interface is disabled.
The interface is testing(3) when a
test is active on the interface.

Interface Group – "ifLastChange" Object
(ifEntry 9)
This object contains the value of "sysUpTime" at the
time the interface entered its current operational state. For
the E1 NTU, this object is only updated for the "up" and
"down" states. This is done since the "testing" state is not
mutually exclusive with the "up" and "down" states.
Interface Group – Input Counters
(objects ifEntry 10 to ifEntry 15)
These objects collect statistics on the data received by
the COM port and the AUX port when these ports are
configured as SNMP management links. For interfaces
that are not configured as an SNMP management link,
these statistics are not provided and an error status is
returned if access is attempted. The objects used to collect
input statistics are listed below:
ifInOctets (ifEntry 10)
ifInUcastPkts (ifEntry 11)
ifInNUcastPkts (ifEntry 12)
ifInDiscards (ifEntry 13)
ifInErrors (ifEntry 14)
ifInUnknownProtos (ifEntry 15)

When configured as an SNMP
management link, up and down are
based on the current state of the
link layer protocol. Otherwise, the
interface is always up(1).
The interface is never in the
testing(3) state.
