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-Configures the LBO (in dB) for T1 interfaces with cable lengths

0>	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-patterncommand.

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, 1-10specifies 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-patterncommand.
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.
