E1/FE1 NIM COMMANDS
clock source [internal | line*]
Configures the source timing used for the interface. Use the no form of this command
to return to the default value.
internal Provides clocking using the internal oscillator.
line* Recovers clock from the E1 circuit.
coding [ami | hdb3*]
Configures the line coding for the E1 physical interface. The settings must match the
line coding supplied on the circuit by the service provider.
ami Configures the line coding for alternate mark inversion (AMI).
hdb3
*
Configures the line coding for high-density bipolar 3 (HDB3).
description <text>
Identifies the specified interface, both physical and virtual (for example, circuit ID,
contact information, etc.), using up to 80 alphanumeric characters.
framing [crc4]
Configures the framing format for the E1 interface. This parameter should match the
framing format provided by the service provider or external device. Use the no form of
this command to return to the default value.
crc4 Enables CRC-4 bits to be transmitted in the outgoing data
stream. Received signal is checked for CRC-4 errors.
loop-alarm-detect
Enables detection of loop alarms on the E1 interface. Use the no form of this command
to disable loop alarm detection. This setting is enabled by default.
loopback network [line | payload]
Initiates a loopback on the interface toward the network. Use the no form of this
command to deactivate the loopback.
line Initiates a metallic loopback of the physical E1 network
interface.
payload Initiates a loopback of the E1 framer (CSU portion) of the E1
network interface.
loopback remote v54
Initiates an E1 remote loopback test (with a V.54 loopback pattern). Use the no form of
this command to disable this feature.
remote-alarm [rai* | ais]
Selects the alarm signaling type to be sent when a loss of frame is detected on the E1
receive signal. Use the no form of this command to disable all transmitted alarms.
rai* Sends a remote alarm indication (RAI) in response to a loss
of frame. Also prevents a received RAI from causing a
change in interface operational status.
ais Sends an alarm indication signal (AIS) as an unframed all-
ones signal
remote-loopback
Configures the interface to respond to loopbacks initiated by a remote unit (or the
service provider). Use the no form of this command to disable this feature. This
setting is enabled by default.
sa4tx-bit [0 | 1*]
Selects the Tx value of Sa4 in this E1 interface. Use the no form of this command to
return to the default value of 1.
show test-pattern
Display results from test patterns inserted using the test-pattern command.
shutdown
Disables the interface (both physical and virtual) so that no data will be passed
through. Use the no form of this command to turn on the interface and allow it to
pass data. By default, all interfaces are disabled.
snmp trap link-status
Controls the Simple Network Management Protocol (SNMP) variable
ifLinkUpDownTrapEnable (RFC2863) to enable (or disable) the interface to send
SNMP traps when there is an interface status change. Use the no form of this
command to disable this trap.
tdm-group <group number> timeslots <1-31> speed [56 | 64*]
Creates a group of contiguous channels on this interface to be used during the
cross-connect process.
<group number> Identifies the created TDM group (valid range: 1 to 255).
timeslots <1-31> Specifies the channels to be used in the TDM group. This can be
entered as a single number representing one of the 31 E1
channel timeslots or as a contiguous group of channels. (For
example, 1-10 specifies the first 10 channels of the E1.)
speed [56 | 64*] Optional. Specifies the individual channel rate on the E1 interface
to be 56 kbps or 64 kbps. The default speed is 64 kbps.
test-pattern [clear | insert | ones | p511 | qrss | zeros]
Activates the built-in pattern generator and begins sending the specified test pattern.
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 an error into the currently active test pattern. Display the
injected error result using the show test-pattern command.
ones Generates a test pattern of continuous ones.
p511 Generates a test pattern of repeating ones and zeros.
qrss Generates a pattern test of random ones and zeros.
zeros Generates a test pattern of continuous zeros.
ts16
Enables timeslot 16 multiframe to be checked on the receive signal. Use the no form
of this command to disable timeslot 16.
* Indicates default values.
