PurposeCommand
Sets the framing on the interface.
• bypass—Configures framing bypass to use the
full T3 or E3 bandwidth.
• bypass-ds3—Configures framing bypass to use
the full T3 bandwidth.
• bypass-e3—Configures framing bypass to use
the full E3 bandwidth.
• c-bit—Specifies C-bit parity framing. This is
the default for T3.
• m13—Specifies M13 framing.
• g751— Specifies G751 framing. This is the
default for E3.
• g832—Specifies G832 framing.
T3
Router(config-if)# framing {bypass | c-bit | m13}
E3
Router(config-if)# framing {bypass | g751| g832}
8-Port Clear-Channel T3/E3 SPA
Router(config-if)# framing {bypass-ds3 | bypass-e3
| c-bit | m13 | g751 | g832}
The following table determines the T3 or E3 mode of the interface based on the framing type configured:
