Version 1.0                           February 2014                               Page 7 of 17
Product Description – Wholesale NGA Fibre Unbundled Access




2. Product Overview
The Fibre Unbundled Access Product provides an enhanced broadband access service, between
the Service Termination Point (STP) at an end-user premises and a Wholesale Ethernet
Interconnect Link (WEIL) at an Operator’s nominated Point of Handover (POH), within the local
exchange area. It is intended to support a mix of time sensitive and high volume applications
including voice, general entertainment (including Broadcast TV), and high speed Internet.

The product is designed to use both copper and fibre as the physical access methodology. The
product supports traffic-based Class of Service.

                                       FUA Product Scope

                                        Figure 1: FUA Product Overview

FUA terminates on a Service Termination Point (STP) on the end-customers premises. This STP
will vary, depending on the access mechanism used. Where Services are delivered over fibre the
STP will be an interface on an Optical Network Terminal. Where Services are delivered over
copper the STP will be a copper Network Terminating Unit. The STP connects to a Next
Generation Access, Access Node (NGA-AN), at the exchange. The WEIL is connected directly to
the NGA-AN.


2.1     Core Components
The eircom Wholesale NGA Product range consists of a number of core components, each of
which must be ordered individually:

     Wholesale Ethernet Interconnect Link (WEIL)1 – This is the high speed link carrying
      aggregated traffic from individual users to the Operator.
     NGA-AN Connectivity – this is the connectivity from the Next Generation Access – Access
      Node (NGA-AN) to the WEIL.
     Fibre Unbundled Access – This is the connectivity to the individual end-customer. A number
      of order types will be available, depending on the access mechanism.

1The Product Description for the WEIL is a separate document. Each NGA Access Node is connected individually to the
Wholesale Ethernet Interconnect Link and presented to the WEIL in its own VLAN.




Version 1.0                                        February 2014                                             Page 8 of 17
Product Description – Wholesale NGA Fibre Unbundled Access




2.2       Traffic-based Class of Service
All traffic carried in Access Network will be assigned to one of three Class of Service (CoS)
queues:

          Expedited Forwarding (EF)
          Assured Forwarding (AF)
          Standard (Best Effort)

The Operator can dynamically map their end-user traffic, to any one of these three categories.
This provides an Operator with the ability to manage and prioritise their upstream and
downstream traffic. The utilisation on the three queues (EF, AF and Best Effortis measured at the
WEIL and used for billing.


2.2.1      Class of Service Marking
Traffic should be marked using 802.1p marking. The marking scheme is as follows:


                        C-VLAN 802.1p Marking          Forwarding Class
                                     4                         EF
                                     2                         AF
                                     0                         BE

                    Figure 2: Mapping of C-VLAN p-bits to Forwarding Classes



For multicast, see Section 2.4, an EF CoS will be automatically applied.



2.2.2      Class of Service Marking by CPE

CPE should use the same 802.1p CoS Marking, as specified in section 2.2.1. This marking will be
honoured in the Access Network and the Wholesale Ethernet Interconnect Link (WEIL).



2.2.3      CoS and Service Bandwidth

An indicative forecast of traffic levels per NGA-AN, by CoS, will be provided by the Operator. This
will be used for capacity management of the NGN-AN, Aggregation Node and interconnecting
links. Subject to viable Operator forecasts, this infrastructure will be managed by eircom to ensure
that there is no congestion. Capacity management of the WEIL will be the responsibility of the
Operator.




Version 1.0                              February 2014                                Page 9 of 17
Product Description – Wholesale NGA Fibre Unbundled Access




2.3    CPE Management
Operator’s can implement their own device management platform for their Residential Gateway
(RG) and other CPE2, e.g. using TR69 Remote Device Protocol for communication with the RG
over the eircom network.


2.4    Multicast Support
The FUA product supports IGMP Snooping and IGMP Proxy, at the NGA-AN, for multicast traffic
handling. A single BTV VLAN (i.e. a dedicated SVLAN) is configured on the WEIL to carry all
multicast traffic from an Operator. The CPE (e.g. a Set-top Box) on the end-users premises uses
the Internet Group Management Protocol (IGMP) for requests to “Join” or “Leave” a broadcast
stream.

Further details are given in the Technical Handbook.




2 In this context CPE (Customers Premises Equipment) refers to Operator’s equipment, subsequent to the Service
Termination Point.

                                            Figure 4: STP for FUA FTTH Access

The end-user Service Termination Point for the FUA FTTH Access Product is a Gigabit Ethernet
Port on the ONT. This is an auto-sensing 10/100/1000 Base-T Ethernet port (suitable for the
insertion of a RJ-45 connector). A single mode fibre patch cord will be used to connect the female
(adapter) SC/APC connector of the NTU to the female (adapter) single mode SC/APC connector
of the ONT.

Further information on the service presentation can be found in the Technical Manual3.

The customer port speed depends on the characteristics of the individual sub-loop up to a
maximum speed of 50Mb/s Downstream, 20Mb/s Upstream.


4.1      FTTC Sub-Loop Profiles
A ‘Profile’ is a set of configuration parameters that govern how a DSL Line operates. The FTTC
Line Profile determines the maximum downstream and upstream speed for that end-Customer
and whether that speed is fixed or adapts to varying line conditions. The FUA FTTC Access
Product supports two profile ranges – one for ‘High Speed Internet’ and one ‘High Stability’ range
intended primarily for Broadcast TV.




      Profile Range                    Available Profiles (Downstream/Upstream in Mbit/s)
      High Speed Internet              50M/20M, 45M,20M, 40M/20M, 35M/15M, 30M/10M,25M/8M, 20M7M, 18M/5M
      Stable/TV                        35M/16M, 30M/16M, 25M/15M, 20M/8M, 20M/10M, 8M/7M

                                         Figure 6: FTTC Sub-Loop Profiles



The High Speed Internet (HSI) range is ‘Rate Adaptive’ in both directions – this means that the
line speed in each direction varies, depending on local line conditions, up to the maximum value
specified by the profile currently set on that line. The ‘Stable’ range is Rate Adaptive upstream
and ‘Fixed’ downstream. This means that the downstream speed is set by the applied profile and
does not vary. High Speed Internet or Stable/TV is selected at Order Submission, but can be
changed subsequently.

4.2      Service Presentation
At the customers’ premises the Operator will access the VDSL2 Service via eircom’s Network
Termination Unit (NTU). The NTU will present the Operator with an RJ-11 female connection. In
certain circumstances NTU equipment will need to be installed, where a suitable Service
Termination Point does not already exist. eircom will provide the Operator with a standardised
Network Terminating Unit (NTU), to be installed and tested by the Operator, subject to agreed
installation standards.

The customers’ side of the Network Termination Unit (NTU) is the final point of eircom
responsibility for the FUA FTTC Access Product. Provision, installation, replacement and
maintenance of any additional equipment/connections on the customer’s side of the NTU is the
responsibility of the Operator.

Further information on the service presentation can be found in the Technical Handbook.4
