SHDSL NIM C
OMMANDS
alarm-threshold
{
loop-attenuation | snr-margin
}
Sets thresholds for specific alarm conditions.
loop-attenuation
Enter a value from 1-127 dB. If signal energy loss on
the loop exceeds the configured value, NetVanta
issues an alarm.
snr-margin
Signal-to-noise ratio margin. Enter a value from
1-15 dB. If the difference in amplitude between the
baseband signal and the noise exceeds the
configured value, NetVanta issues an alarm.
alias
<text>
Comment line to provide the text name assigned by the SNMP network management
system.
boot alternate-image
Executes new code after a firmware upgrade.
description
<text>
Comment line to provide an identifier for this interface (for example, circuit ID, contact
information, etc.).
equipment-type
{
co |cpe
}
Determines the operating mode for the SHDSL interface. The default for this
command is
cpe
.
co
Use this option only in a campus environment when
operating two SHDSL NIMs back-to-back. In this
setup, configure the Master NIM to
co
and the Slave
NIM to
cpe
.
cpe
Use this option when interfacing directly with your
service provider or when acting as the Slave NIM in
a campus environment.
inband-detection
Enables inband loopback pattern detection on the SHDSL interface.
inband-protocol
{
pn127 | v54
}
Designates the inband loopback pattern to send/detect on the SHDSL interface.
pn127
Selects PN127 as the inband loopback pattern to
send/detect.
v54
Selects V.54 as the inband loopback pattern to send/
detect.
linerate
<selections are 200 to 2312 kbps in 64k increments>
Defines the line rate for the SHDSL interface (the value includes 8 kbps of framing
overhead). This command is functional only in
co
operating mode (see the description
for the
equipment-type
command). The default for this command is 2056 kbps. The
first two selections listed (72 and 136 kbps) are not supported by this unit.
loopback
{
network |remote
}
Initiates a loopback on the SHDSL interface.
network
Initiates a loopback test, looping the data toward the
network.
remote
Sends a network loopback request to the remote
unit to initiate a loopback. This command is
functional only in
co
operating mode (see the
description for the
equipment-type
command).
outage-retrain
Causes the SHDSL interface to force the SHDSL retrain sequence (which takes the
line down temporarily) if the interface detects more than ten consecutive errored
seconds. A retrain is forced in hopes that the newly retrained line will perform better.
snmp
{
trap | trap link-status
}
Controls SNMP trap functionality for the SHDSL interface.
trap
Enables traps for the SHDSL interface.
trap link-status
Controls the SNMP variable,
ifLinkUpDownTrapEnable (RFC 2863), which
enables/disables the interface to send SNMP traps
when there is an interface status change.
test-pattern
{
2^15 | clear, | insert | show
}
Activates built-in pattern generation, which can be used to verify a data path when
used in conjunction with an active loopback.
2^15
Initiates test pattern generation from the unit.
clear
Clears the test pattern results.
insert
Inserts a single error into the currently active test
pattern.
show
Displays the test pattern results.
