NetVanta E1/FE1 Network Interface Module (NIM) P/N 1200868L1

E1/FE1 NIM COMMANDS

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	Provides clocking using the internal oscillator.
line*	Recovers clock from the E1 circuit.
coding [ami hdb3*]

Configures the line coding for the E1 physical interface. The settings must match the line coding supplied on the circuit by the service provider.

ami	Configures the line coding for alternate mark inversion (AMI).
hdb3*	Configures the line coding for high-density bipolar 3 (HDB3).
description <text>

Identifies the specified interface, both physical and virtual (for example, circuit ID, contact information, etc.), using up to 80 alphanumeric characters.

framing [crc4]

Configures the framing format for the E1 interface. This parameter should match the framing format provided by the service provider or external device. Use the no form of this command to return to the default value.

crc4	Enables CRC-4 bits to be transmitted in the outgoing data
	stream. Received signal is checked for CRC-4 errors.
loop-alarm-detect

Enables detection of loop alarms on the E1 interface. Use the no form of this command to disable loop alarm detection. This setting is enabled by default.

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 E1 network
	interface.
payload	Initiates a loopback of the E1 framer (CSU portion) of the E1
	network interface.
loopback remote v54

Initiates an E1 remote loopback test (with a V.54 loopback pattern). Use the no form of this command to disable this feature.

remote-alarm [rai* ais]

Selects the alarm signaling type to be sent when a loss of frame is detected on the E1 receive signal. Use the no form of this command to disable all transmitted alarms.

rai*	Sends 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.
ais	Sends an alarm indication signal (AIS) as an unframed all-
	ones signal

remote-loopback

Configures the interface to respond to loopbacks initiated by a remote unit (or the service provider). Use the no form of this command to disable this feature. This setting is enabled by default.

sa4tx-bit [0 1*]

Selects the Tx value of Sa4 in this E1 interface. Use the no form of this command to return to the default value of 1.

show test-pattern

Display results from test patterns inserted using the test-patterncommand.

shutdown

Disables the interface (both physical and virtual) so that no data will be passed through. Use the no form of this command to turn on the interface and allow it to pass data. By default, all interfaces are disabled.

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> timeslots <1-31>speed [56 64*]

Creates a group of contiguous channels on this interface to be used during the cross-connect process.

<group number> Identifies the created TDM group (valid range: 1 to 255).

timeslots <1-31>Specifies the channels to be used in the TDM group. This can be entered as a single number representing one of the 31 E1 channel timeslots or as a contiguous group of channels. (For example, 1-10specifies the first 10 channels of the E1.)

speed [56 64*] Optional. Specifies the individual channel rate on the E1 interface 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 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.
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 pattern test of random ones and zeros.
zeros	Generates a test pattern of continuous zeros.
ts16

Enables timeslot 16 multiframe to be checked on the receive signal. Use the no form of this command to disable timeslot 16.

* Indicates default values.
