Note: See the 7210 SAS-M Services guide for more information on CESoPSN services.
Default
all-ones
Parameters
all-ones — Defines the 8 bit value to be transmitted as 11111111.
pattern — Transmits a user-defined pattern.
Values
idle-signal-fill
Syntax idle-signal-fill {all-ones | pattern pattern}
no idle-signal-fill
Context config>port>tdm>ds1>channel-group
config>port>tdm>e1>channel-group
Description This command defines the signaling pattern to be transmitted (4-bit value) when the circuit emulation
service is not operational or temporarily experiences underrun conditions. This command is only valid for
CES with CAS.
Note: See the 7210 SAS-M Services guide for more information on CESoPSN
Default all-ones
Parameters all-ones — Defines the 4 bit value to be transmitted as 1111.
pattern — Transmits a user-defined pattern.
Values
loopback
Syntax loopback {line | internal | fdl-ansi | fdl-bellcore | payload-ansi}
no loopback
Context config>port>tdm>ds1
config>port>tdm>e1
Note: Only line and internal options are supported for "e1".
Description This command puts the specified port or channel into a loopback mode. A line loopback, loops frames
received on the corresponding port or channel back towards the transmit (egress) direction before reaching
the framer. The bit stream is not reframed. The electrical signal is regenerated by the Tx line interface unit
(LIU) and the timing is provided by the Rx LIU.
An internal loopback, loops the frames from the local router back to the framer. This is usually referred to as
an equipment loopback. The Tx signal is looped back and received by the interface.
Note: The loopback command is not saved to the system configuration.
The no form of this command disables the specified type of loopback.
