T1/FT1 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 Configures the unit to provide clocking using the internal
oscillator.
line
*
Configures the unit to recover clocking from the T1 circuit.
coding [ami | b8zs*]
Configures the line coding for a T1 physical interface. This setting must match the line
coding supplied on the circuit by the service provider.
ami Configures the line coding for alternate mark inversion (AMI).
b8zs
*
Configures the line coding for bipolar eight zero substitution
(B8ZS).
fdl [ansi* | att | none]
Configures the format for the facility data link (FDL) channel on the T1 circuit. FDL
channels are only available on point-to-point circuits. Use the no form of this command
to return to the default value.
ansi
*
Configures the FDL for ANSI T1.403 standard.
att Configures the FDL for AT&T TR 54016 standard.
none Disables FDL on this circuit.
framing [d4 | esf*]
Configures the framing format for the T1 interface. This parameter should match the
framing format supplied by your network provider. Use the no form of this command to
return to the default value.
d4 Specifies D4 superframe (SF) format.
esf
*
Specifies extended superframe (ESF) format.
lbo [long <-22.5, -15, -7.5- 0> | short <0 to 655>]
Configures the line build out (LBO) for the T1 interface. Use the no form of this
command to return to the default value.
long <-22.5, -15, -7.5- 0> Configures the LBO (in dB) for T1 interfaces with cable
lengths greater than 655 feet. Choices are -22.5, -15, -7.5,
and 0 dB.
short <0 to 655> Configures the LBO (in feet) for T1 interfaces with cable
lengths less than 655 feet. Range is 0 to 655 feet.
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 T1 network
interface.
payload Initiates a loopback of the T1 framer (CSU portion) of the T1
network interface.
loopback remote line [fdl | inband]
Sends a loopback code to the remote unit to initiate a line loopback. Use the no form of
this command to send a loopdown code to the remote unit to deactivate the loopback.
fdl Uses the facility data link (FDL) to initiate a full 1.544 Mbps
physical (metallic) loopback of the signal received by the
remote unit from the network.
inband Uses the inband channel to initiate a full 1.544 Mbps physical
physical (metallic) loopback of the signal received from the
network.
loopback remote payload
Sends a loopback code to the remote unit to initiate a payload loopback. A payload
loopback is a 1.536 Mbps loopback of the payload data received from the network
maintaining bit-sequence integrity for the information bits by synchronizing
(regenerating) the timing. Use the no form of this command to send a loopdown code
to the remote unit to deactivate the loopback.
remote-alarm [rai]
Selects the alarm signaling type to be sent when a loss of frame is detected on the T1
receive signal. Use the no form of this command to disable all transmitted alarms.
rai Specifies sending 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.
remote-loopback
Configures the interface to respond to loopbacks initiated by a remote unit (or service
provider). Use the no form of this command to disable this feature.
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> timeslot <1-24> speed 64*
Creates a group of contiguous DS0s on this interface to be used during the cross-
connect process.
<group number> Identifies the created TDM group (valid range: 1 to 255).
timeslots <1-24> Specifies the DS0s to be used in the TDM group. This can be
entered as a single number representing one of the 24 T1
channel timeslots or as a contiguous group of DS0s. (For
example, 1-10 specifies the first 10 channels of the T1.)
speed 64* Optional. Specifies the individual DS0 rate on the T1 interface to
be 64 kbps.
test-pattern [clear | errors | 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.
errors Displays 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 test pattern of random ones and zeros.
zeros Generates a test pattern of continuous zeros.
* Indicates default values.
