ACCULINK 317x E1 DSU/CSU
E-4 December 1996 3170-A2-GB20-20
Interface Group – “ifMtu” Object (ifEntry 4)
This object identifies the lar
gest datagram that can be
sent or received on the interface. It is applicable only to
the interface configured as the SNMP management link.
This object is zero for all other interfaces.
Interface Group – “ifSpeed” Object (ifEntry 5)
This object provides the interface’s current bandwidth
in bits per second. The value of this object for each
interface is specified as follows:
E1 Interfaces:
2,048,000 bps.
COM and
AUX:
The currently configured data rate
for the port.
Data Ports: The currently configured data rate
for the port when the port is
allocated to one of the E1
interfaces or to another port as a
backup. If the port is not allocated
the data rate is defined as zero.
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 DSU/CSU other than the COM port. Only the
following values are supported by the E1 DSU/CSU:
• 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
Drop/Insert:
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.
COM Port: 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.
AUX Port:
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 down(2).
The interface is never in the
testing(3) state.
Data Ports: The interface is up(1) when the
port is assigned to the E1 interface
or another data port as a backup,
and both CTS and DSR are ON.
The interface is down(2) when the
port is unassigned, or either CTS
or DSR is OFF.
The interface is testing(3) when a
test is active on the interface.
