framing (DS1)
Syntax framing {esf | sf | ds1-unframed}
Context config>port>tdm>ds1
Description This command specifies the DS1 framing to be used for the port.
The ds1-unframed parameter allows the configuration of an unstructured DS1 channel on
the following:
• 16-port T1/E1 ASAP Adapter card
• 32-port T1/E1 ASAP Adapter card
• 2-port OC3/STM1 Channelized Adapter card
• 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card
• 4-port DS3/E3 Adapter card (DS3 ports only)
• 4-port T1/E1 and RS-232 Combination module (T1/E1 ports only)
When an unframed DS1 channel is shut down, it sends the AIS pattern to the far-end DS1.
The far end does not react to the AIS pattern if the far-end DS1 is configured as unframed. If
the far-end DS1 is configured as framed, the far end declares AIS. The operational status
remains up and no alarms are generated while the near end is operationally down. This is
normal behavior for unframed G.703 mode.
Default esf
Parameters esf — configures the DS1 port for extended superframe framing
sf — configures the DS1 port for superframe framing
ds1-unframed — specifies DS1 unframed (G.703) mode for DS1 interfaces. DS1
unframed mode is only applicable if the encapsulation type is set to cem or ppp-auto.
framing (E1)
Syntax framing {no-crc-g704 | g704 | e1-unframed}
Context config>port>tdm>e1
Description This command specifies the E1 framing to be used for the port.
The e1-unframed parameter allows the configuration of an unstructured E1 channel on the
following:
• 16-port T1/E1 ASAP Adapter card
• 32-port T1/E1 ASAP Adapter card
• 2-port OC3/STM1 Channelized Adapter card
• 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card
