T1/FT1 NIM C

OMMANDS

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 line-status
Controls the Simple Network Management Protocol (SNMP) variable

dsx1LineStatusChangeTrapEnable (RFC2495) 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.
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.
snmp trap threshold-reached
Controls the Simple Network Management Protocol (SNMP) variable

adGenAOSDs1ThresholdReached (adGenAOSDs1-Ext MIB) to enable the interface to send

SNMP traps when a DS1 performance counter threshold is reached. Use the no form of this

command to disable this trap.
tdm-group <group number> timeslots <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

Specifies the individual DS0 rate on the T1 interface to be 64 kbps.

This is the only supported speed on this module.

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.

p215

Generates a pseudorandom test pattern sequence based on a 15-bit

shift register.

p220

Generates a pseudorandom test pattern sequence based on a 20-bit

shift register.

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.
