Cisco ASR 1000 Series Software Configuration Guide

PurposeCommand or Action
• number—Allowed values are 0 to 34368. The default is 34368.
Enables scrambling for the E3 physical layer interface. The default is no
scramble.
Router(config-controller)# scramble
Step 3
Sets the national reserved bits on an E3 line. The default is 0.Router(config-controller)# national bit
{0 | 1}
Step 4
Sets the framing on the interface, where:Router(config-controller)# framing
{bypass | g751 | g832}
Step 5
• bypass—Configures framing bypass to use the full E3 bandwidth.
• g751— Specifies g751 framing. This is the default for E3.
• g832—Specifies g832 framing.
Selects the CRC size in bits, where:Router(config-controller)# crc {16 | 32}
Step 6
• 16—16-bit CRC. This is the default
• 32—32-bit CRC.
Specifies loopback is enabled for the unchannelized E3 serial interface,
where:
Router(config-controller)# loopback
{network | local | remote}
Step 7
• local loopback—Loops data from the transmit path to the receive
path.
• network loopback—Loops data received on the external port to the
transmit path and back out the external port.
• remote loopback—Sends a far-end alarm control request to the remote
end requesting that it enter into a network line loopback.
Shuts down the E3 interface.Router(config-controller)# shutdown
Step 8
Sends a BERT pattern on an E3 line, where:Router(config-controller)# bert pattern
pattern interval 1-14400
Step 9
• pattern—Specifies the length of the repeating BERT test pattern.
Allowed values are 2^15, 2^20, 2^23, 0s, 1s, and alt-0-1.
• interval time—Specifies the duration of the BERT test, in minutes.
The interval can be a value from 1 to 14400.
Verifying the Interface Configuration
Use the show interface serial command to verify the interface configuration:
Router# show interface serial 1/0/0.1/1:0
