framing [crc4]
Use the framing command to configure the framing format for the E1 interface. This parameter should
match the framing format set on the external device. Use the no form of this command to return to the
default value.
Syntax Description
crc4 Enables CRC4 bits to be transmitted in the outgoing data stream. Also, the
received signal is checked for CRC4 errors.
Default Values
By default, crc4 is enabled.
Command Modes
(config-e1 1/1)# E1 or G.703 Interface Configuration Mode required.
(config-e1 1/2)#
Functional Notes
The framing value must match the configuration of the E1 circuit. A mis-match will result in a loss of frame
alarm.
Usage Examples
The following example configures the E1 interface for CRC4 framing:
(config)#interface e1 1/1
(config-e1 1/1)#framing crc4
