Configuration Commands
Page 284 7710 SR OS Interface Configuration Guide
feac-loop-respond
Syntax [ no ] feac-loop-respond
Context config>port>tdm>ds3
config>port>tdm>e3
Description This command enables the associated DS-3 interface to respond to remote loop signals.
The DS-3 far-end alarm and control (FEAC) signal is used to send alarm or status information from
the far-end terminal back to the local terminal. DS-3 loopbacks at the far-end terminal from the local
terminal are initiated.
The no form of this command prevents the associated DS-3/E-3 interface from responding to remote
loop signals.
Default no feac-loop-respond
framing (DS-1)
Syntax framing { esf | sf | ds1-unframed }
Context config>port>>tdm>ds1
Description This command specifies the DS-1 framing to be used with the associated channel.
Default DS1: esf
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 ds-1 unframed (G.703) mode for DS-1 interfaces. This parameter allows
the configuration of an unstructured DS-1 channel on a CES MDA. In G.704, timeslot 0 is used
to carry timing information by a service provider, thus, only 31 slots are made available to the
end user. In G.703, all 32 time slots are available to the end user. Timing is provided by the end
user. When an e1-unframed channel is shutdown, it sends the AIS pattern to the far-end DS-1
which does not react. The operational status remains up and no alarms are generated while the
near-end (shutdown) is operationally down. This is normal behavior since the G.703 option does
not have framing. G.703 framing is only applicable for FR, PPP, and C-HDLC encapsulations.
