SHDSL NIM COMMANDS
alarm-threshold [loop-attenuation | snr-margin]
Sets thresholds for specific alarm conditions. Use the no form of this command to
disable threshold settings.
loop-attenuation <value> Specifies a loop-attenuation threshold value from
1 to 127 dB. If signal energy loss on the loop
exceeds the configured value, the router issues an
alarm.
snr-margin <value> Specifies a value for signal-to-noise ratio (SNR)
margin from 1 to 15 dB. If the difference in amplitude
between the baseband signal and the noise exceeds
the configured value, the router issues an alarm.
boot alternate-image
Executes new code after a firmware upgrade.
equipment-type [co |cpe*]
Determines the operating mode for the SHDSL interface.
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. Use the no form
of this command to disable inband-detection.
inband-protocol [pn127 | v54]
Designates the inband loopback pattern to send/detect on the SHDSL interface. Use
the no form of this command to return to default.
pn127 Selects PN127 as the inband loopback pattern to
send/detect.
v54 Selects V.54 as the inband loopback pattern to
send/detect.
linerate <value>
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.
<value> Specifies the line rate in kbps. Range: 200 to
2312 kbps in 64k increments.
loopback network
Initiates a loopback test on the SHDSL network on the SHDSL interface, looping the
data toward the network. Use the no form of this command to deactivate the
loopback.
loopback remote
Sends a loopback request to the remote unit. This command is functional only in co
operating mode (see the description for the equipment-type command). Use the no
form of this command to send a loopdown code to the remote unit to deactivate the
loopback.
loopback remote inband
Injects the selected inband loop-up pattern into the data stream to cause a loopback
at the far end. Use the no form of this command to inject a loop-down pattern into the
data stream to cause an existing inband loopback at the far end to cease.
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.
Use the no version of the command to disable this feature.
test-pattern [clear | insert | p215]
Activates the built-in pattern generator and begins sending the selected test pattern
toward the network. Can be used to verify a data path when used in conjunction with
an active loopback. Use the no form of this command to cease pattern generation.
clear Clears the test pattern error count.
insert Inserts a single error into the currently active test
pattern.
p215 Generates a pseudorandom test pattern sequence
based on a 15-bit shift register.
*Indicates default values.
