4. Configuration Options
4-36 September 2002 9128-A2-GB20-80
Network Initiated PLB
Possible Settings: Enable, Disable
Default Setting: Enable
Allows the initiation and termination of the paylo ad loopback (PLB) to be controlled by the
receipt of PLB-Actuate and PLB-Release commands from the network.
Display Conditions
This option only appears when Line Framing Format is set to ESF.
Enable PLB is controlled by PLB-Actuate and PLB-Release commands. Receiving a
PLB-Actuate command causes the system to enter a payload loopback (provided a PLB
can be performed in the units current state). Receiving a PLB-Release command
terminates the PLB.
Disable The FrameSaver unit ignores the PLB-Actuate and PLB-Release commands.
NOTE: When disabled, the unit is not in compliance with ANSI T1.403 or
AT&T TR 54016.
Network Initiated DCLB
Possible Settings: Disable, V.54_&_ANSI
Default Setting: V.54_&_ANSI
Allows the initiation and termination of the Data Channel Loopback (DCLB V.54 Loop 2) to
be controlled by the receipt of a DCLB-actuate or DCLB-release sequence (either V.54 or
FT1-ANSI compliant) from the network on the DS0s used f or the network frame relay link.
When enabled and a DCLB-activate sequence is received, the unit initiates a DCLB on
the network interface. When a DCLB-release sequence is received, the DCLB is st opped.
Disable DCLB-actuate and DCLB-release sequences are ignored.
V.54_&_ANSI DCLB-actuate and DCLB-releas e sequ ences that comply wi th either V.54
or ANSI T1.403, Annex B standard will be recognized and will control initiation and
termination of a DCLB for the network frame relay link. The actuate and release
sequences do not need to match (for example, a DCLB started with a V .54 actuate
sequence can be stopped with an FT1 release sequence).
ANSI Performance Report Messages
Possible Settings: Enable, Disable
Default Setting: Disable
Specifies whether ANSI T1.403 compliance performance report messages (PRMs) are
generated and sent to the network over the ESF facility data link every second.
Display Conditions
This option only appears when Line Framing Format is set to ESF.
Enable Generates and sends PRMs.
Disable Does not generate and send PRMs.
