Provisioning tools – TL1 and CLI

TL1 – Transaction Language number 1

• for the provisioning of the GPON transport layer
• lt equipment provisioning can also be done using CLI
• pon, ont, … up to ontenet provisioning can be done using TL1

CLI – Command Line Interface

• for provisioning the ihub
• as well as the services/facilities on iacm

PON functions

transport traffic

• GEM encapsulated
• ethernet frames

polling for new ONTs

• based on ranging

BER 10-5 signal degraded signal failed configurable

• based on ranging
• configurable polling freq.

BER measurements

• BIP field in PCB
• configurable meas. period

Provision PON – AMS

PON is automatically created when you create the board

• you can only modify it

select node (NE) rack subrack slot pon port unlock

• save

Provision PON – CLI

Configure pon interface 1/1/1/2 admin-state up

• the (downstream) laser is activated
• ONTs which are connected/powered on start ranging
• this generates an alarm

minor alarm occurred for pon 1/1/1/2 : SERNUM = ALCLF9A0F50D, SLID = 12345

PONs are created at LT creation time

• state admin-state down

Provision PON – CLI

Configure pon interface 1/1/1/2

• Label -> name of the PON, string with length <= 80
• Ber-calc-period -> BER measurement period (unit 1/10 sec)
• Polling-period -> polling period for ONTs (unit 1/10 sec)
• Sig-degrade-th -> signal degraded threshold [4…10]
• Sig-fail-th -> signal failed threshold [3…8]

• Sig-fail-th -> signal failed threshold [3…8]
• Fec-dn -> Forward Error Detection for downstream (enable/disable)
• Raman-reduct -> Raman Reduction (enable/disable)
• Closest-ont -> distance of closest ONT [0 … 40km]

ONT Software flow

ONT ONT FTP

ONT ISAM AMS Download Download passive Download active

ONT software banks

active bank passive bank active bank: what the ONT tries to boot up with if the ONT fails to boot with what is in the active bank it will use the

RAM

planned software what you intend to run in RAM active sw what is actually running in RAM passive sw what is in the passive bank

it will use the passive bank if the active software is different from the planned, the P-OLT tries to download the planned software to the passive bank

ONT software banks

Active and Passive banks can only be accessed via OMCI

• ONT must be in the “unlocked” state

If Active and Planned SW are misaligned, a minor alarm is generated (CFG : SW Version mismatch)

• ONT will not be operational as long as this alarm is active

m

• Copy/Paste Active SW into Planned SW field to get rid of the alarm.

m

ONT SW related alarms

SWDLFAIL

• SW Download Failed
• Something went wrong with the download process

SWACTFAIL

• SW Activation Failed
• Downloaded SW could not be activated on the ONT

M m

SWDLFILE

• File missing or file error
• The SW file string mentioned in the SWVERPLND doesn’t exist on the P-OLT

SWDLIP (not really an alarm)

• SW Download In Progress
• SW is being downloaded from P-OLT towards the ONT over the OMCI channel

SW Perspective

Download software to ISAM Options when using scenario 2

Necessary steps and scenario’s

• 1. FTP ONT software files to AMS server
• 2. Prepare ONT software files (per ONT type) on AMS server
• 3. Download ONT software onto NE

possible scenarios:

• 1. Manual sw management (basic or pre-provisioning)
• 2. Automatic sw management based on AMS
• 3. Automatic sw management based on NE

Step 1 : Copy ONT software from CD to AMS

Prerequisite step

• ONT software files must be present on AMS
• directory:
• /var/opt/ams/shared/ams-<version>/ne/software/ONT

FTP

AMS

Step 2 : ONT Software file preparation : overview

HW version: one ONT Type can have multiple hardware implementations

Step 2 : ONT Software file preparation : List of Hardware Info (OPTIONAL)

Allows to add a new type

• f Hardware

Step 2 : ONT Software file preparation : Add ONT Load

First select the correct ONT Type from the hardware list ONT File Name: ONT software version residing on AMS server Major NE SW Version: used for automatic sw management (see later)

Load Type: using VoIP or not?

Step 3 : Download ONT software to NE

• select NE(s)
• select ONT type
• select SW load

Step 3 : Which ONT software to use?

ONT software must be available on the NE before it can be downloaded

• nto the ONT!

when you plan the SW for the ONT, you have to add a “3’’ to the name 3FE50853AIAA05

Provisioning ONTs

ONTs can be provisioned

• while already physically connected to the PON:

Post-provisioning

• while not physically connected to the PON at all:

Pre-provisioning Post-provisioning

Provisioning ONTs (cont.)

serial number based

• identify the ONT by its serial number

ALCLA0A28965 ONT not connected? ALARM

Subscriber Location ID (SLID) based

• identify the ONT by its subscriber location id
• SLID up to 10 characters long
• SLID is configured beforehand in the ONT

TEACHER NO ALARM

Discovered ONT in case of basic provisioning

alarm at AMS: minor

Serial number of ONT

alarm at CLI and TL1: minor

• … minor alarm occurred for pon 1/1/3/2 : SERNUM = …, SLID = …
• "PON-1-1-3-2,PON:MN,NEWONT,NSA,,,,:

CFG alarm: new ONT discovered

Choosing the scenario

‘from AMS’: used for manual sw management and automatic based on AMS ‘from NE’: used for automatic sw management based on NE

Scenarios on ONT details

Planned software:

• ‘UNPLANNED’ -> scenario 1 and 2
• Specific version (‘3FE…’) -> scenario 1
• AUTO : automatic from NE -> scenario 3

• AUTO : automatic from NE -> scenario 3

Object details

‘Planned Variant’ not filled in ‘Planned Software’ is set to UNPLANNED ‘Download Software’ is set to DISABLED

AMS will set planned software first to ‘UNPLANNED’. Upon detection of ‘software version mismatch’ alarm, the AMS will fill in the correct version.

Automatic software management based on NE

When choosing ‘From NE’, the NE will be responsible for the SW Version Control Table. With each download of ONT Software towards NE, an entry will be created in the Version Control Table. Download to Passive bank

Download to Passive bank Download to Active bank, which will trigger a reset of ONT

Object details

When provisioning the ONT , the AMS will set ‘planned software’ to AUTO and the ‘Planned Variant’ to DO

Automatic download if hardware version and planned variant has a matching entry in the ONT software control table

• Allows mass download of ONT software to ONTs that match key criteria specified in the

select node … ont 55 create planned ont-card

Provision ONT Card - CLI The ONTs do report which ONT Cards (or ont slots in CLI) are available, but they still need to be provisioned!

Provision Ethernet Port - CLI The UNIs are automatically created during the provisioning

• f the ont slot (ONT Card), they only still need to be configured!

Configure interface port uni:1/1/1/2/33/1/1 admin-up

you still need to provision the bridge port in the ISAM!

Provision bridge port - AMS

when the ONTENET and UNI was provisioned using AMS, the bridge port was created automatically!

adapt bridge port settings, if needed:

if needed: e.g. increase #MAC addresses

Provision bridge port

also referred to as …

• … configuring the interworking function

syntax:

• configure bridge port <rack/shelf/slot/port/ont/ontcard/ontenet>

Basic GPON QoS

Ingress QoS profile: p-bits and traffic classes

p-bit-to-queue mapping: 2-step configuration via Traffic Classes (TC)

• TC-to-queue mapping (fixed, system-wide setting)
• based on a 4 queue or 8 queue (fixed) constellation:

• p-bit-to-TC mapping (L2 FWR setting)
• ingress Profile: dot1p0 TCx1, dot1p1 TCx2, etc

Ingress QoS profile: CLI configuration

configure qos profiles ingress-qos all-in-one dot1-p0-tc 0 dot1-p1-tc 0 … dot1-p7-tc 0

all p-bits are mapped to the same TC hence all traffic enters one single queue

configure vlan id 150 mode residential-bridge (secure-forwarding) in-qos-prof-name name:all-in-one

the p-bit mappings are actually/also needed on the ONT they are downloaded to the ONT when provisioning the bridge port!

Ingress QoS profile: AMS configuration

Bandwidth profile: T-CONT types

• Bandwidth parameters of T-CONT define the T-CONT type
• DBA will issue grants to for the T-CONT to ensure that average rate does not exceed

the maximum of CIR, AIR and EIR

• fixed BW T-CONT type 1: rate limiting to CIR
• best-effort BW T-CONT type 4: rate limiting to EIR
