Default
looped-timed
Parameters
loop-timed — The link recovers the clock from the received data stream.
node-timed — The link uses the internal clock when transmitting data. The internal clock is a free-running
clock.
adaptive — The clocking is derived from the incoming pseudowire packets from the MPLS network.
encap-type
Syntax encap-type {cem}
no-encap-type
Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description
This command configures the encapsulation method used to on the specified port, path, or channel for the
port on the T1/E1 CES MDA. This parameter can be set on access ports. For access mode, only cem
encapsulation is supported.
Default no encap-type
Parameters cem — Specifies the encapsulation type as circuit emulation mode for TDM pseudowires on the CES MDA.
framing (DS-1)
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 a T1/E1 MDA. If a DS1 unframed channel is shut down,
the channel sends an AIS pattern to the far-end DS1. If the far-end DS1 is configured as unframed, it does
not react to the AIS pattern. If the far-end DS1 is configured as framed, the far end declares the AIS pattern.
The operational status remains up and no alarms are generated when the near end is operationally down.
This is normal behavior for unframed G.703 mode.
Default
dsl-unframed
Parameters
esf — Configures the DS-1 port for extended super frame framing.
sf — Configures the DS-1 port for super frame framing.
ds1-unframed — Specifies the DS1 unframed (G.703) mode for DS1 interfaces. DS1 unframed mode is
only applicable if the encapsulation type is set to cem.
