PON

The PON profile controls the configuration of PON ports on the OLT. 

   

 

 

PON Profile Attributes 

Attribute  Values  Default  Req Description
Name Printable string N/A Y The name of the PON Profile
alarm-down-cir true | false False N Whether to alarm when the actual pon bandwidth is exceeding the configured PON threshold.  Indicates that the PON is congested and needs to be addressed if consistently happening.
Alarm-down-eir true | false False N

Whether to alarm when the actual pon bandwidth is exceeding the configured PON threshold.  Indicates that the PON is congested and needs to be addressed if consistently happens.
Alarm-excessive-arrival true | false True N Whether to alarm when an ONT arrives on the PON too many times close together.  Typically indicative of an issue with the ONT or the transmission facility.
Alarm-up-cir true | false  False N Whether to alarm when the upstream guaranteed bandwidth is oversubscribed.
Alarm-up-eir true | false False N Whether to alarm when the actual bandwidth is exceeding the configured threshold.
Auto-convert-ont true | false False N Whether to auto convert an ONT when the ONT type is determined to not match the configured ONT.  This allows provisioining to be preserved whenever the ONT type changes.
Auto-create-max-ont-id 1.64 64 N The maximum ONT ID to be used when performing auto creates of ONTs.
Auto-create-min-ont-id 1.64 1 N A timer use to determine the timeout on messages between the authenticator and RADIUS server.
Auto-create-onts true | false False N The minimum ONT ID to be used when auto creating ONTs.
Discover-onts true | false True N Whether to automatically discover new ONTs on the PON.  Typically would be set to true and ONTs would be added to the unexpected ONT list.  Certain secure sites or if doing data rate testing, this feature should be disabled.
Down-cir-threshold 0..100 100 N Percent of the committed information rate that when exceeded will cause an alarm.
Down-eir-threshold 0..100 95 N Percent of the PON bandwidth that when utilized will cause an alarm on the PON.
Enable-auto-disable     N ???? Open question???
Enable-range-locking true | false True N Allows locking of ONT to the same distance.  Prevents ONT from being moved. 
Enable-roaming-lock true | false False N Whether the ONT is allowed to be configured in more than one location.  Typically only used for lab or other situations where a device is moved back and forth between two locations.  Can also be useful for PON copy actions. 
Fec-enabled true | false False N Whether Forward Error Correction is enabled on the PON.  It will typically increase the SNR of the link by 3dB and is helpful in situations where the fiber facility is impaired.  It will reduce the PON bandwidth to approximately 8.5G.
integration-period <1..60> 1 N The time over which to integrate the tcss in minutes.
Path-protection true | false False N Whether to enable path protection.  If path protection is enabled and PPG is present then if the uplink loses connectivity to the network, the PON will switch to the other PON.  Allows routing around an OLT that might have been isolated.
Periods-to-monitor 1..10 3 N The number of periods over which to integrate the TCA alarms.
Pon-reach reach-0-20 |
reach-0-30 |
reach-20-40 |
reach-30-50		 Reach-0-20 N The supported reaches of the PON. 
  • reach-0-20: closest ont 0km, farthest 20km
  • reach-0-30 closest ont 0km, farthest 30km
  • reach-20-40 closest 20km, farthest 40km
  • reach-30-50 closest 30km, farthest 50km
Note: Standard states that closest to farthest ONT can only differ by 20km.  Also the split ratios will be lower at the longer distances to ensure sufficient optical budget.  Please consult Tellabs on all longer distance applications.
Pon-type gpon | xgspon Xgspon N The PON standard the system is configured for.  Only gpon and xgspon are supported at this time.
Storm-control-broadcast-percent 0..100 10 N The percent of the PON bandwidth that is allowed to be consumed by broadcast traffic.  Any traffic above the configured percentage will be dropped.
Storm-control-unknown-multicast-percent 0..100 30 N The percent of the PON bandwidth allowed to be used by flooded multicast.  IGMP controlled multicast is not affected by this setting.  Excess flooded multicast above the percentage is dropped.
Up-ber-fail-threshold -10..-4 -4 N The exponent for bit error loss ratios that when exceeded will alarm and fail the PON.  -4 equates to 10e-4 for example.
Up-ber-maint-threshold -10..-4 -4 N The maintenance threshold for bit interleaved parity errors.  If the ratio is exceeded, the PON will be alarmed.  Indicates that the PON is operational but in need of optical maintenance to ensure QoS.  The ber threshold indicates the error ratio allowed before alarming where -6 indicates a ber of 10e-6 or higher the PON is alarmed.
Up-cir-threshold 0..100 100 N The percent of the PON total guaranteed bandwidth that when exceeded should be alarmed.  Indicates the PON is oversubscribed when alarmed.
Up-eir-threshold 0..100 95  N The percent of the PON total bandwidth when exceeded would be alarmed.  Used for determining when bandwidth is nearing exhaustion.
