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.
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 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.
Default flags (0x7E)
no flags (ATM)
Parameters flags — Specifies that 0x7E is used as the idle cycle flag.
ones — Specifies that 0xFF is used as the idle cycle flag.
