Interface Configuration
7210 SAS M, T, X, R6, R12, Mxp, S, Sx Interface Configuration Guide Page 213
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.
framing (E-1)
Syntax framing {no-crc-g704 | g704 | e1-unframed}
Context config>port>tdm>e1
Description Platforms Supported: 7210 SAS-M.
This command specifies the E-1 framing to be used for the port.
Default e1-unframed
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 E1 unframed (G.703) mode for E1 interfaces. E1 unframed mode is only
applicable if the encapsulation type is set to ‘cem’.
idle-cycle-flag
Syntax idle-cycle-flag {flags | ones}
Context config>port>tdm>ds1>channel-group
config>port>tdm>ds3
config>port>tdm>e1
config>port>tdm>e1>channel-group
config>port>tdm>e3
Description Platforms Supported: 7210 SAS-M.
This command configures the value that the HDLC TDM DS-0, E-1, E-3, DS-1, or DS-3 interface transmits
during idle cycles. For ATM ports/channels/channel-groups, the configuration does not apply and only the
no form is accepted.
The no form of this command reverts the idle cycle flag to the default value.
