T1/FT1 NIM C

OMMANDS

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. 

Note: the Dual T1 NIM supports a single clock source for both T1 

interfaces. Changing the clock source on one T1 interface automatically affects the 

configuration of the other T1 interface. For example, setting the clock source to 

line

 on the first 

T1 configures the clock source of the second T1 as 

through

.

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 alternate T1 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. 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.

test-pattern [clear | errors | insert | ones | p215 | p220 | 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.

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.
