loopback remote v54
Initiates an E1 remote loopback test (with a V54 loopback pattern). Deactivate using
the no loopback remote v54 command.
remote-alarm [rai* | ais]
Selects the alarm signaling type to be sent when a loss of frame is detected on the
E1 receive signal.
rai* Specifies Remote Alarm Indication.
ais Specifies Alarm Indication Signal.
remote-loopback
Enables acceptance of remote loopback requests on this E1 interface. Deny
acceptance using the no remote-loopback command. This setting is enabled by
default.
sa4tx-bit [0 | 1*]
Assigns a value to the Tx spare bit in position 4.
show test-pattern
Shows current test pattern error count.
shutdown
Turns off the interface. The no version of this command turns the interface on and
allows it to pass data.
snmp trap link-status
Enables the unit interface to send SNMP traps when there is an interface status
change and controls the SNMP variable, ifLinkUpDownTrapEnable.
tdm-group <group#> timeslots <DS0 range> speed [56 | 64*]
Creates a group of contiguous DS0s on this interface to be used during the cross-
connect process.
<group#> Identifies this TDM group using a number label.
<DS0 range> Identifies DS0s in this group in the form: <starting DS0 -
ending DS0>. Valid range is 1 through 31.
56 | 64* Optional. Specifies a channel rate of 56 kbps or 64 kbps.
test pattern [clear | insert | ones | p511 | qrss | zeros]
Initiates sending the specified test pattern.
clear Clears the test pattern error count.
insert Inserts an error into currently active test pattern.
ones Generates a pattern of continuous ones.
p511 Generates a repeating pattern of ones and zeros.
qrss Generates a random test pattern.
zeros Generates a pattern of continuous zeros.
ts16
Enables timeslot 16 multiframe to be checked on the receive signal.
* Indicates default values.

An optional Dial Backup Interface Module (DIM) is
required for dial backup applications.
E1/FE1 + G.703 NIM COMMANDS
clock source [line* | internal | through]
Configures the source timing used for the interface.
line* Recovers clock from the E1 circuit.
internal Provides clocking using the internal oscillator.
through Recovers clock from the circuit connected
to the G.703 interface.
coding [ami | hdb3*]
Configures the line coding for the E1 or G.703 physical interface. This setting must
match the line coding supplied on the circuit by the service provider.
ami Specifies Alternate Mark Inversion.
hdb3* Specifies High-Density Bipolar 3.
framing [crc4]
Configures the framing format of the E1 interface.
crc4 Enables CRC-4 framing.
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. Deactivate using the no
loopback network command.
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.
