Configuration Commands
Page 284 7750 SR OS Interface Configuration Guide
Parameters g704 — Configure the E-1 port for G.704 framing.
no-crc-g70 — Configures the E-1 for G.704 with no CRC4.
e1-unframed — Specifies E-1 unframed (G.703) mode for E-1 interfaces. This parameter also
allows the configuration of an unstructured E-1 channel on an ASAP or 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 E-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
CHDLC and CEM encapsulations.
framing (DS3)
Syntax framing { c-bit | m23 }
Context config>port>tdm>ds3
Description This command specifies DS-3 framing for the associated DS-3 port or channel.
Default c-bit
Parameters c-bit — Configures the DS-3 port/channels for C-Bit framing.
m23 — Configures the DS-3 port/channel for M23 framing.
framing (E-3)
Syntax framing { g751 | g832 }
Context config>port>tdm>e3
Description This command specifies E-3 framing for the associated E-3 port or channel.
Default E-3 non-ATM: g751 and cannot be changed.
E-3 ATM: g832 and cannot be changed.
Parameters g751 — Configures the E-3 port/channel for g751 framing.
g832 — Configures the E-3 port/channel for g832 framing.
