Framing (Ds3); Framing (E-3); Idle-Cycle-Flag - Alcatel-Lucent 7750 SR OS Interface Configuration Manual

Configuration Commands
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

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:
E-3 ATM:
Parameters g751 — Configures the E-3 port/channel for g751 framing.
g832 — Configures the E-3 port/channel for g832 framing.

idle-cycle-flag

Syntax idle-cycle-flag {flags | ones}

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.
