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

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

11


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

12


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] 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 banks

RAM

planned software what you intend to run in RAMactive sw what is actually running in RAMpassive sw what is in the 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 passive bank

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

16


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

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

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

• 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

19


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:

4. Manual sw management (basic or pre-provisioning)

5. Automatic sw management based on AMS

6. Automatic sw management based on NE

20


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

21


Step 2 : ONT Software file preparation : overview

HW version: one ONT Type can have multiple hardware implementations

22


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

Allows to add a new type

of Hardware

23


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?

24


Step 3 : Download ONT software to NE

select NE(s)

select ONT type

select SW load

25


Step 3 : Which ONT software to use?ONT software must be available on the NE before it can be downloaded onto the ONT!

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

ONT provisioning3

27


Provisioning ONTsONTs can be provisioned while already physically connected to the PON:

while not physically connected to the PON at all:

Pre-provisioning

Post-provisioning

28


Provisioning ONTs (cont.)• serial number based identify the ONT by its serial number

• 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

29


Discovered ONT in case of basic provisioning• alarm at AMS: minor

• 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

Serial number of ONT

30


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

31


Scenarios on ONT details

Planned software:

• ‘UNPLANNED’ -> scenario 1 and 2

• Specific version (‘3FE…’) -> scenario 1

• AUTO : automatic from NE -> scenario 3

Provision ONT – Serial number based –CLI• Configure equipment ont interface 1/1/1/2/33 Sw-ver-pland -> software version planned (if not know, set to UNPLANNED)

Sernum -> consists of 2 parts: <VendorID:serial_number> e.g. ALCL:A0A3F342 Vendor ID: 4 char (e.g. ALCL for Alcatel-Lucent)

Actual serial number : 8 char

Subslocid -> left to its default value of WILDCARD

Battery-bkup -> presence of battery backup

Desc1 and Desc2 -> two description fields

Enable-aes -> enable AES in downstream

Admin-state -> set to up to bring In Service

37


Changing planned software version

CLI

Show equipment ont interface 1/1/1/2/33 detail To look up the active software version on the ONT

Configure equipment ont interface 1/1/1/2/33 sw-ver-pland ...

38


ONT Operational data

Show equipment ont operational-data 1/1/1/2/33 detail

39


ONT pre-provisioning3.2

40


Pre-Provisioning on ONT – SLID based

once the ONT is connected to the PON the P-OLT records the SLID and the serial number

automatic status change: to unlocked (in service)

this allows you to do pre-provisioning of the ONTCARD, services, … without the system generating any alarms!

TEACHERconnect the ONT to the PON

TEACHER

no alarm, even when the ONT is disconnected from the PON

41


Pre-Provisioning SLID on ONT

•ONT need configure SLID pre-provisioning. SLID configuration method is different for each types of ONT.

Subslocid -> Subscriber Location ID, string with maximum of 20 chars

Sernum -> left to its default value: ALCL:00000000

ONT Card provisioning4

47


Provision ONT Card – AMS (1/2)• example of a detected ONT Card:

48


Provision ONT Card – AMS (2/2)• select node … ont 55 create planned ont-card

49


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!

• Configure equipment ont slot 1/1/1/2/33/1

Planned-card-type 10_100baset, pots, vdsl2, video, ds1, e1, vdsl2pots, ethpots

Plndnumdataports [0…16]

Plndnumvoiceports [0…16]

• This will automatically provision the UNI

but they will be in the status out of service

Ethernet Port provisioning5

51


Provision Ethernet Port – AMS (1/2)

52


Provision Ethernet Port – AMS (2/2)• provision the UNI With AMS this also automatically creates bridge port!

53


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

of 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! See next chapter

54


Bridge port provisioning6

55


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:

e.g. increase #MAC addresses

56


Provision bridge port• also referred to as … … configuring the interworking function

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

• example: configure bridge port 1/1/3/3/33/1/1

Basic GPON QoS7

58


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

TC Queue TC Queue7 3 7 76 3 6 65 2 5 54 2 4 43 1 3 32 1 2 21 0 1 10 0 0 0

configure vlan id 150 mode residential-bridge

(secure-forwarding)

in-qos-prof-name name:all-in-one

all p-bits are mapped to the same TC

hence all traffic enters one single queue

the p-bit mappings are actually/also needed on the ONT

they are downloaded to the ONT when provisioning the bridge port!
