Chapter 1

SUMMARY

The ONT is an Optical Terminal Equipment unit for Passive Optical Networks (PON) termination in a (Fiber-To-The-

Home) FTTH / (Fiber-To-The-Cell) FTTC service delivery architecture. ONT communicates with the OLT (Optical

Line Terminal) for the PON side and with the customer’s premises for the client side. This equipment supports tripleplay services - high speed internet (HSI), voice (VoIP) and video (IPTV and/or RF Overlay) as like as implementing the mobile backhaul service in the access component in the FTTC architecture. The use of the GPON fiber access technology standard architecture does allow a significant service delivery increase when compared with traditional xDSL technology.

The ONT equipment technology is based on GEM (GPON Encapsulation Method), and complies with ITU-T G.984.x. recommendation as like as G.984.4 (OMCI) ensuring interoperability with major GPON OLT vendors.

These base functionalities, together with the support for bit rates of up to 2.5 Gbps (downstream) and 1.24 Gbps

(upstream), a splitting ratio of up to 1:64 in a single fiber and a distance range of up to 60 km, make the GPON technology and the ONT the most efficient option for passive optical network topologies.

Together with multi-vendor OLT interoperability (BBF.247 certified), other differentiated features of the ONT product family are the embedded RF Video Overlay as well as the chance to have several TV channel packs by means of using remote managed analog RF video overlay filters. The use of an embedded optical reflective component also increases probing resolution in case of FTTH probing.

As opposed to the point-to-point architecture, in which there is one physical port per client in the Central Office, in this

GPON point-to-multipoint architecture there is one single laser and photo-detector in the Central Office (CO) to serve up to 64 CPEs. All the Optical Distribution Network is built by means of passive equipment modules with a long MTBF value and very low OPEX costs. This leads to a significant cost reduction in this kind of networks rollout.

DESCRIPTION

ONT Main Functionalities

The ONT is aimed for customer premises and complies with the ITU-T G.984.x recommendation in order to transport

(over GPON) and deliver (to premises domain) the full pack of broadband services.

Broadband service applications are commonly referred as below:



High speed internet (HSI);



Voice (VoIP) services (SIP/MEGACO H.248);



TV (whether IPTV or analog RF video overlay);



Mobile Backhaul.

The multiplay environment is thus reinforced when combining the upper referred services.

Services

The ONT supports the following services:



Voice over IP (VoIP) service;



Broadband Internet Access:

 High bit rate data for High Speed Internet service – HSI;

 IPTV service.



Analog video service (RF Overlay);



Mobile Backhaul service.


Internet Over GPON

GPON is a point-to-multipoint passive optical network, in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 1-64.

A PON consists of an optical line terminal (OLT) at the central office and a number of optical network terminals (ONT) at the customer premises. Downstream signals are broadcasted to all premises sharing multiple fibers. Encryption can prevent eavesdropping. Upstream signals are combined using a multiple access protocol (Time Division Multiple

Access - TDMA). The OLT queues data to the various ONT terminal in order to provide time slot assignments for upstream communication.

In Figure 4 it is shown a scenario for Internet service user access through an ISP network.

Figure 4: Optical fiber Internet service user access

The communication between client equipment (ONT) and the ISP access routers (MAN edge) is made by an optical fiber-based passive architecture (ITU-T G.984 Recommendation). The GPON network acts as a Layer 2 Ethernet


5


metropolitan network. Access network assures and controls the media (MAC) communication through a TDMA scheme, introducing GEM (GPON Encapsulation Method) in between to adapt TDM layer to Ethernet.

The used protocol stack is shown in Figure 5.

Figure 5: Stack of protocols for GPON architecture

Several transmission containers (T-CONT) are assigned to each user. Each T-CONT has an associated GEM port and each GEM port has a VLAN identifier and an 802.1p priority level.

The ONT classifies the traffic depending on the VLAN and the marked priority, and routes it over the corresponding T-

CONT/GEM port. Thus for frame multiplexing, GEM and T-CONT ports are used for uplink while the downlink only use the GEM ports feature.

The CPE architecture is shown in Figure 6

6


Figure 6: CPE architecture


Internet access is provided through the Home Gateway (HG) to obtain a public Internet IP.

The home gateway allocates a private IP address to each client through DHCP, making the addresses conversion through NAT for Internet output.

The home gateway establishes PPPoE session with the ISP network, which authenticates the user for Internet access.

The user must be a service subscriber and the service must be provisioned at the OLT where the ONT is connected to

IPTV Service

For the IPTV service the ONT also behaves like a Layer 2 bridging device. For this service, the ONT has a specific

GEM PORT for Multicast. This same GEM PORT is requested by the user in order have access to the various IPTV channels. Every time a user request a new channel, the ONT will send to OLT a IGMP packet requesting that Channel.

The ONT is also responsible for implementing the snooping for the channels that the user requests.

RF Video Overlay

PON RF video overlay service is the way to deliver a broadcast TV service over a PON fiber network. This video overlay service is foreseen to provide mainly broadcast video transmission in contrast to unicast and/or multicast IP video transmission which is used for IPTV and/or Video-On-Demand having the need for a Set-Top-Box or a Smart TV at the customer premises.

Standardization bodies (ITU for GPON and IEEE for GEPON) have excluded the use of the 1550 -1560nm wavelength window for IP transmission on PONs and have even continued with this approach for the upcoming 10GPON and

10GEPON standards. The 1550-1560nm wavelength windows is thus exclusively reserved for the video overlay transmission, and by that mean an option to off-load unicast and/or multicast video transmission from the IP PON transmission link.


7


Within the ONT RF Video Overlay feature implementation is also an option to deliver a flavored TV channel pack service by the use of a group of embedded RF analog filters that can be remotely managed (NMS) in order to enable

each individual commercial TV Channel pack, Figure 7.

Figure 7: RF Overlay analog filter feature

Typically an extra fiber testing signal (1650nm) for optical network probing is also added to the PON optical communication link.

Voice

8

ONT voice service provisioning could be made through OLT configurations over OMCI messages or could be downloaded (FTP) from the OLT up to the ONT after the ONT registration on the PON network. The ONT SFU equipments have the ability to deliver the Voice service over two types of interface:

Logical interface (VLAN encapsulation)

If the ONT has no FXS ports and the VoIP service is transparently forwarded from the OLT up to the Home Gateway

(and vice versa) within a previously defined voice VLAN. ONT respects the defined priority and implements the traffic encapsulation from its own Ethernet interface into a specific T-CONT/GEM-Port over the PON interface and up to the

OLT equipment.

Physical interface (FXS ports)

The ONT has physical RJ11 FXS interfaces. In this version of the ONT equipment, voice interfaces are terminated in the equipment by means of FXS (RJ11) connections. The RJ11 analog terminals adapter function is auto/selfconfigured, integrated (analog/VoIP) and associated with a defined SIP or Megaco (H.248) user.

The ONT will allow VoIP or NGN (Next Generation Network) traffic from devices connected to the RJ11 or RJ45 interfaces, towards the same internal VLAN.



Apart of the SIP and Megaco (H.248) self-configuration, it is also possible to make modifications in the voice service configurations by updating the ONT SW through download from the OLT via OMCI.

The ONT equipment has a DHCP client (ONT-4GE-2FXS) to get an IP address, alternatively the ONT could be configured with a static IP (ONT-4GE-2FXS). The configuration of the static IP or DHCP client is related to the WAN side and is enabled by the OLT.

Multiple QoS Per VLAN

The ONT supports 802.1p QoS per VLAN services in which several flows (one per allowed pbit) are embedded in the same VLAN. According to the applied configuration, the ONT performs a per-flow QoS policy: dropping traffic marked with not allowed pbits and limiting to the configured value the data rate of the allowed flows.

The ONT performs transparent VLAN translation. It is transparent to upper layer protocols, such as ARP, RIP, DHCP,

IGMP, PPP, etc.

Mobile Backhaul

Due to the large increase on the bandwidth demand of the mobile backhaul networks to support 3G/4G services, PON networks are a natural option for its access component. ONT also supports this mobile backhaul service by mean of a

Layer 2 bridging communication channel. Depending on the interconnection of the mobile backhaul network architecture, ONT transports mobile data traffic over a defined combination of VLAN/GEM PORT/T-CONT. This same configuration should be known and provisioned at the OLT and upper layer network architecture.

Policing / Rate Limiting

Downstream QoS

The OLT system provides several QoS mechanisms, that can be targeted to the flow characterized by one or two VLAN according with the type of service, or can be targeted to the packets priority, where each p-bit is mapped in one of eight queues of each port.

For each of OLT ports are associated eight queues, for each of these queues is possible to configure the p-bit mapping in one of the queues, the scheduler type (Strict Priority or Weighted Fair Queuing) and the minimum and maximum bandwidth of each queue.

In the downstream direction, Figure 8, the ingress traffic first passes by a policer configured to each ONT service, which

is defined by one or two tags. After this the traffic is put in a queue according with the p-bit/queue mapping. Each of these queues is associated with a scheduler and a policer. Then the traffic flows to the GPON interface and when it arrives to the ONT it will pass by a mapping block which will map the traffic in one of the eight queues according with the p-bits, these queues have a Strict Priority scheduler in order to guarantee that the most prioritized traffic passes first.


9


Figure 8: Downstream QoS Diagram

Upstream QoS

In the upstream direction, Figure 9, for each T-CONT the ingress traffic in the ONT passes by a mapping block that

maps the traffic in one of the eight queues according with the p-bit, these queues have a Strict Priority Scheduler. The

ONT “waits” until the OLT assigns a transmission timeslot for that T-CONT, so that the most prioritized queues are the ones that transmit first. In the OLT ingress, the traffic is put into a queue according with what is defined in the queue/pbit mapping. Each of these queues has an associated scheduler and policer that control the traffic sent to the uplink.

Dynamic Bandwidth Allocation (DBA)

The DBA (Dynamic Bandwidth Allocation) is available in order to optimize the upstream bandwidth. This mechanism

consists in defining an adequate T-CONT to the service traffic in question, Figure 10. There are five types of T-CONT,

defined by the Fixed, Assured and Maximum Parameters:



Type 1: Only fixed Bandwidth;



Type 2: Only Assured Bandwidth;



Type 3: Assured + Maximum Bandwidth;



Type 4: Only Maximum Bandwidth (Best Effort);

Interfaces

GPON

The ONT GPON layer as G.984.x uses 1490nm downstream and 1310nm upstream of the optical wavelengh, with

2,488Gbps downstream and 1,244Gbps upstream by using an SC/APC protected optical connector.

Ethernet

Ethernet is the wired LAN technology and is revised in the IEEE 802.3 standard. At the OSI reference system, Ethernet is at the Data Link layer. In the ONT equipment the LAN type of physical interface is 10/100/1000BASE-T AUTO-

MIX Ethernet type over RJ45 connectors.

RF Overlay

Broadcast video signal travels over fiber from the CO in the 1550nm wavelength and is demuxed and converted in the

ONT to a F connector (75 Ohm) RF Overlay interface to deliver a RF TV signal going from 47MHz up to 1 GHz of

12



bandwidth. As it was already referred in one of the previous sub-chapters, ONT may also implement multiple analog filtering of the RF Interface in order to turn the open RF Spectrum in a group of sliced TV channels packs that are remotely enabled from the NMS.

* ONT RX= -8~-30 dBm (The ONT sensitivity assumes the use of the optional RS (255,239) FEC capability of the

G-PON TC layer with the current class B+ ONU detector technology; The ONU overload is set at –8 dBm to be common with the class B+ value, even though in this application –10 dBm is sufficient).

Optical solution: B+ and C+.

Connector type: SC/APC.

IEC 60825-1: "Class 1 Laser Product''.

The B+ and C+ triplexer is embedded on the ONT equipment version.

ONU Single Fiber - G.984.2 (03/2003) + G.984.2 Amd 1 (02/2006) and 2 (03/2008), G.983.3 (03/2001).

Optical Metering

The equipment measures the downstream received power from the OLT in 1490nm and reports this value through

OMCI. The accuracy of the measurement is +/- 3dBm, maximum. Optionally, ONT has also the chance to have an embedded optical reflective component in order to increase the FTTH probing capabilities in a 50 centimeters resolution factor, which turns to have a single probing system to probe all GPON network ONTs even when its number increases over Million customers.

Wavelength Filtering

The optical interface has WDM filters that allow GPON coexistence with RF video services (1550-1560nm) and the new generation of NGPON1 technology, according to G.984.5 Recommendation.

ITU-T Rec. G987.1 is also granted for XGPON, (following FSAN NG-PON2).

In order to face the final user´s demands, current GPON networks have to confront the first evolution in terms of terminals equipments and actual infrastructure. Migration will be available through a new wavelength planning, by allowing the co-existence of two different technologies over the same fiber. The ITU-T Rec. G987.1 provides a mechanism for GPON to XGPON migration with the possibility to achieve 2.5Gbps upstream path. Nominally downstream will be 10 Gbps.

The next figure, Figure 11, depicts the wavelength planning of ITU-T Rec. G987.1

Figure 11: Wavelength planning

In order to accomplish to that plan, the upstream wavelength for GPON must be restricted to ONU (ONT) equipment based on the ordinary DFB lasers, while the XGPON downstream signal range is defined from 1575 nm to 1580 nm and the XGPON upstream signal from 1260 nm to 1280 nm. For the coexistence of XGPON and GPON over the same fiber,


15

▀ GPON/Ethernet Characteristics

the CO requires a WDM filter that combines the downstream signal (1490 nm, 1555 nm and 1577 nm), isolating the

1310 nm and 1270 nm upstream signal, with the video signal. Also the wavelength of 1650 nm, used for fiber monitoring, has to be handled.

In addition, ONT devices require the use of a triplexer type transceiver that include an integrated filter or a discrete

WDM filter to distinguish the different signals that may be present on the fiber. The current networks, equipped with

ONT in accordance with the current ITU-T Rec. G984.5, will be easily updated to XGPON.

Class B+ optical budget are the nominal requirement for coexistence of GPON and XGPON over the same optical fiber.

Taking in account this requirement, the fiber network architecture will not limit the future of the service provider business since GPON architectures, respecting B+ class of the GPON, are easily updated by placing newest terminal equipments, namely XOLT and XONT, and by replacing the current WDM filter by the new one in order to handle the new XGPON signals.

XGPON must support/emulate all GPON legacy services in case of total migration.

Like GPON, XGPON is required to support triple play services (data, voice and video), as well as mobile backhauling

(accurate frequency/phase/time synchronization) application through its high quality of service and high bit rate feature capabilities. Access to Ethernet services such as point-to-point, multipoint-to-multipoint and rooted-multipoint Ethernet

Virtual Connection services should be provided. Finally, as a global requirement, XG-PON needs to support IPv6.

GPON/Ethernet Characteristics

SETUP

Before Installing Your ONT Device



Check for site’s environmental conditions and look for power and optical access points nearby.



Do not install the device in environments where the temperature or humidity exceeds the standard limits.



This device is a passive cooling device. There are thermal holes in the surface of the box. To prevent the overheating do not obstruct these thermal holes.



The ONT device is not designed for outdoor setup. Please place it in a convenient indoor/cabinet environment.



Use only the provided power kit. The use of a 3rd party power adapter may not guarantee its proper operation.



To avoid any hazard or damage in your eyes, please never look directly into a fiber optic connector.



Never assume that the laser beam is inactive or that the optical fiber is switched off.

How To Setup Your ONT

The ONT may be installed horizontally on a flat surface, wall mounted and ETSI rack (ONT-MBH), quick steps for both of these setups are described below.

Wall-mount



Remove the ONT lower cover;



Mount the cover on the wall using two screws inserted into the mountings shown in Figure 12 (c). The lower

mounting is used to regulate the spatial orientation of the box. The space between the two screws should be about 4.8 cm;



Place the optical cable in one of the openings, (a) or (b) shown in Figure 12;



Pass the optical cable, in a clockwise direction, round the circular guide inside the ONT, wrapping it round as many times as necessary;



Fit the ONT into the cover as shown in Figure 12;



Attach the fiber to the optical connector inside the ONT;



Place a 3 mm plastic clip round the support and the optical cable before the point at which the cable exits the

box Figure 12 d). Tighten this just enough to ensure the optical fiber will not move;



Close the ONT.

CONFIGURATION

ONT Activation

The ONT activation process has a distributed set of procedures that allow the connection of a inactive equipment to a

PON network. This configuration is done following the procedure described in the OMCI protocol.

Customization

For customization process, the requirements specified in the G.984.4, G.984.5 and ‘Implementer’s Guide’ in the

G.984.4 v1 are taken into account.

Software Download from the OLT

The software download is made following the OMCI-based procedure included in the ‘Implementer’s Guide’ of the

G.984.4 Recommendation.

The Managed Entity (ME) in charge of managing the software download is named Software Image. Per each ME containing independently-manageable software, the ONT creates two software images. Each image will have three attributes:



Valid - if it has been verified that it’s content is an image with executable code;



Committed - if once the ONT is rebooted, it is loaded and executed;



Active - if it is loaded and it is being executed in the ONT.

There can be only one active image and only one committed image at a given moment. The ONT goes through a series of states in order to download and activate a software image. Each state is defined according to the states of the variables of both images. The OLT controls the ONT state through a series of commands:



Start download

 It starts the software download sequence. This action is only valid for inactive and non-committed software images;



Download section

 It downloads a section of a software image. This action is only valid for an image that is being downloaded;



End download

 It indicates the end of a download sequence, providing the CRC and information about version for the final verification of the downloaded software image. This action is only valid for a software image that is being downloaded;


25

▀ Customization



Activate image

 It loads/executes a valid software image. When this action is applied to an inactive software image, the execution of the current code image is suspended, the associated software image is loaded from the non-volatile memory and the execution of the new code image is started. When this action is applied over a software image that is active, a reboot is executed;



Commit image

 It selects a valid SW image to be loaded and executed by default when the ONT is restarted;



Composition of the Software Image

 A software image is divided into sections of 31 bytes, with one section per OMCC message and each section protected by the CRC of the OMCC. A group of sections makes up a window, and a group of windows constituting the image.
