SLV Sample Interval (secs)
Possible Settings: 10 – 3600
Default Setting: 60
Sets the inband communications interval between FrameSaver SLV devices. Inband
communications are used to pass frames that calculate latency, as well as transmission
success and other SLV information.
10 – 3600 – Sets the SLV Sample Interval (secs) in seconds.
SLV Delivery Ratio
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether communication of Frame and Data Delivery Ratios (FDR/DDR)
between FrameSaver SLV devices is enabled. To use this capability, both ends of all
PVCs must be FrameSaver SLV devices. If some of the units are FrameSaver 9124s or
9624s, they must be running software version 1.2 or higher.
Enable – An extra byte for FDR/DDR statistics collection is included with each frame,
which is used at the receiving end to determine the amount of data dropped by the
network.
Disable – Extra byte is not included.
DLCI Down on SLV Timeout
Available Settings: Enable, Disable
Default Setting: Disable
Determines whether a DLCI is declared Inactive after the configured threshold for SLV
Timeout has been exceeded.
NOTE: This option does not apply to multiplexed DLCIs connected to a far-end unit
with hardware bypass capability.
Enable – After the configured threshold for missed SLV packets has been exceeded,
the DLCI’s status is changed to Inactive.
Disable – An SLV Timeout Error Event does not affect DLCI status.
SLV Timeout Error Event Threshold
Available Settings: 1, 2, 3, 4 . . . 20
Default Setting: 3
Specifies the number of consecutive missed SLV communications that must be
detected before a DLCI Inactive status is declared.
1–20 – Sets the limit for these error events.
