Profile
Port |
The port assigned to this interface. |
Oper Status |
Indicates the operational status of the GPON OLT port. |
Admin Status |
The administrative status of the interface. Up: The interface is enabled and up, and the status of the interface should become standby or operational. Down: The interface is disabled and down, and the status of the interface whould become shutdown. |
Description |
Test description of the interface. |
Link Status Trap |
Indicates whether linkUp/linkDown traps should be generated for this interface. enabled for interfaces which do not operate on top of any other interface. disabled if they do. |
Max RT Propagation Delay |
Maximum round trip propagation delay. Combined with maximum ONU response time and preassigned delay determines maximum logical PON distance. Default 200 usec |
Max ONU Response Time |
Combined with maximum round trip propagation delay, determines maximum logical PON distance. Default 50 |
Preassigned EQD |
Combined with maximum round trip propagation delay and maximum ONU response time determines max logical PON distance. Default 0 |
LOS Alpha |
Number of Loss-of-Signal occurrences to trigger an alarm. Default 4 |
LOF Alpha |
Number of Loss-of-Frame occurrences to trigger an alarm. Default 4 |
LOAM Alpha |
Number of loss-of-OAM occurrences to trigger an alarm. Default 3 |
Scrambler |
Default enabled |
FEC Mode |
Enables or disables forward error correction. Default disabled |
Auto Learn |
Enable or disable password auto-learn mode. Default enabled |
Power Level |
OLT power level. For the Broadlight 3000, values will be rounded down to one of 0, 3, or 6. Default 0 |
Guard Bit Count |
Number of guard bits for upstream transmission. Default 32 |
DBA Mode |
Dynamic Bandwidth Allocation (DBA) is specified in the ITU standard 984.3. This feature is used to grant upstream bandwidth to ONUs based on their demand and service-level agreement. The OLT will grant ONUs an increase in their slot time for more bandwidth while granting a reduced slot time to others. Through DBA, a GPON link can be oversubscribed for upstream traffic, and improve bandwidth usage efficiency. Working mode values: predictive piggyback wholeReport Default predictive |
GEM Block Size |
Basic unit in bytes used by all ONUs for DBA reports of their queue occupancy (for piggyback and whole-reportDBA only) Default 16 |
Upstream BER Interval |
Interval for upstream bit error rate calculation. Default 5000 |
Downstream BER Interval |
Interval used for downstream bit error rate calculation. Default 500 |
BER Signal Fail Threshold |
Threshold is 10**(-N) for signal fail. Default 3 |
BER Signal Degrade Threshold |
Threshold is 10**(-N) for signal degrade. Must exceed sf threshold. Default 5 |
FEC Request |
Indicates whether OLT turns on FEC indication for all Alloc-Id in the Upstream Bandwidth Map. Default Disabled |
Key Exchange |
Specifies whether Single Key exchange should be performed during ONU activation process. Default disabled |
Min RT Propagation Delay |
If the closest ONU location is known, the GPON stack uses this value in order to limit the size of the quiet zone. Default 0 |
Min ONU Response Time |
GPON stack uses this value in order to limit the size of the quiet zone. Default 10 |
EQD measure Cycle |
Defines the number of measurement cycles in the Ranging process. Default 5 |
Drift Control Interval |
Defines the interval of periodic monitoring on drifts of upstream data. Default 1000 |
Drift Control Limit |
Indicates the limit of upstream data drift. Default 3 |
Alloc Cycle Length |
Alloc-ID assignment map cycle length. Default 2 |
Min Upstream Alloc |
Size of minimal upstream allocation per frame. Default 16 |
Ack Timeout |
Timeout length of Acknowledge message. Default 2000 |
PLS Max Alloc Size |
Indicates a size of unassigned allocation that should be attached to the end of ranging window. Default 120 |
DBA Cycle |
The Dynamic Bandwidth Allocation (DBA) cycle determines the DBA interval size. Its an integer multiplicand of 2 mili-seconds. The range of values for the DBA cycle can be between 2ms-10ms. Default 2 ms |
SR-DBA Block Size |
For DBA of SR type, the block size defines the resolution of the status reports per PON link. Default 48 bytes. |
Protect. Switchover Timer |
If the system receives a LOS alarm for a link in Active state, the link state changes to Switch Over Pending state. If the actual switch-over does not happen after this Protect. Switchover Timer expires, the link will go back to Active state. |
BIP Error Monitoring |
Disable or enable the BIP error monitoring. Values: disabled The BIP error monitoring feature is disabled. monitorOnly Monitor BIP errors. When ONU crosses the BIP error threshold, trigger a local alarm and send trap to the Network Management System. blockOnError Monitor BIP errors. When ONU crosses the BIP error threshold, trigger a local alarm , send trap to the Network Management System, disable ONU ranging and set ONU line status to DSA (i.e. disabled). Default: monitorOnly |
BIP Errors Per Sample Threshold |
If the number of BIP errors per sample exceeds this threshold, it is counted as an errored sample. Default: 100 |
BIP Errored Samples Threshold |
If the number of errored samples exceed this sample threshold, report and disable the onu if in blockOnError mode, otherwise simply report the threshold as being exceeded. Default: 10 |
BIP Max Sample Gap |
If two adjacent errored samples were taken farther apart than this threshold, do not count the earlier sample as an errored sample. This value is in the unit of seconds. Default: 10 |
