T1/FT1 + DSX-1 NIM COMMANDS
clock source [internal | line* | through]
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.
through Configures the unit to recover clocking from the circuit connected to
the DSX-1 interface.
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. 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. (T1 interface only.)
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.
show test-pattern
Displays results from test patterns inserted using the test-pattern command.
signaling-mode [message-oriented | none | robbed-bit*]
Configures the signaling type (robbed-bit for voice or clear channel for data) for the DS0s
mapped to the DSX-1 port.
message-oriented Specifies clear channel signaling on Channel 24 only. Use this
signaling type with QSIG installations.
none Specifies clear channel signaling on all 24 DS0s. Use this signaling
type with data-only or PRI DSX-1 installations.
robbed-bit* Specifies robbed bit signaling on all DS0s. Use this signaling type for
voice-only DSX-1 applications.
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 [56 | 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 [56 | 64*] Optional. Specifies the individual DS0 rate on the T1 and DSX-1
interfaces 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 begin 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 test pattern of random ones and zeros.
zeros Generates a test pattern of continuous zeros.
* Indicates default values.
