NetVanta T1/FT1 + DSX-1 Network Interface Module (NIM) P/N 1202863L1

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.

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 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, 1-10specifies 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 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.

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.

* Indicates default values.
