1 Introduction The purpose of this document is to provide a description of the open eir Symmetrical Ethernet Access product. This document is subject to review and will be re-issued to reflect changes as new developments are introduced which shall be communicated in accordance with agreed practices. Any specific technology mentioned in this document is current as at date of issue and is for guidance purposes only. open eir reserves the right to adapt the technology used to deliver Wholesale Symmetrical Ethernet Access. This document is without prejudice to any future position that may be adopted by open eir in respect of Wholesale Symmetrical Ethernet Access. It should be read in conjunction with the relevant associated open eir documents (where appropriate, reference offer, process manual and SLA). 1.1 Wholesale Symmetrical Ethernet Access Overview Wholesale Symmetrical Ethernet Access is a product that enables an Operator to provide a physical Wholesale Symmetrical Ethernet Access circuit from an end user site to an NGN node, and to provide WSEA logical access(es) (one per available UNI port 1 on an open eir NTU) from an end user site to a nominated Operator Point of Handover (POH) via the open eir core network and a Wholesale Ethernet Interconnect Link (WEIL) as outlined in Figure 1. On the Unified Gateway (UG) an operator places one (1) single UG order for a WSEA circuit. In so doing the Operator provides open eir with the details required to place two (2) internal orders: 1. the WSEA Physical Access order (this is from the open eir NTU located at an Operator end user site; to the physical port on the serving open eir NGN node) 2. the WSEA Logical Access order (this is from the UNI port (optical or electrical) on an open eir Both the WSEA Physical and the WSEA Logical elements are explained in further details throughout this document. The WSEA Logical Access element is also referred to as a WES circuit and this WES 1. For WSEA Physical access circuits of up to1gb/s the circuit id begins with SEA512xxxxxx (irrespective of the handover type). 2. For WSEA Physical access circuits of 10Gb/s the circuit id begins with SEA513xxxxxx for CSH and SEA517xxxxxx for IBH. 3. The WSEA logical access(es) / WES circuit ID begins in all cases with WES586xxxxxx. 1 For up to 1Gb WSEA services an Operator must select an available UNI port for each additional WSEA logical access, specifying the interface. The total bandwidth of all WSEA logical accesses cannot exceed the total bandwidth of the WSEA physical access. 1606/082/2018 Version 5.0 FinalProposed 8

The WSEA may be provided to the nominated POH as Customer Sited Handover (CSH) or In-Building Handover (IBH) 2.

Wholesale Symmetrical Ethernet Access - Logical Wholesale Symmetrical Ethernet Access NGN Core Network open eir NGN Node open eir NGN Node Wholesale Ethernet Interconnect Link Figure 1a: Wholesale Symmetrical Ethernet Fibre Access showing WSEA and WEIL terminating on the same NGN Node for up to 1Gb/s services ed with In certain cases the Wholesale Symmetrical Ethernet Access and its associated Wholesale Ethernet Interconnect Link connection may be within the same serving exchange area and therefore may be connected to the same open eir NGN Node. Wholesale Symmetrical Ethernet Access / Wholesale Ethernet Interconnect Link connections served off the same open eir NGN Node provide the capability to configure the Wholesale Symmetrical Ethernet Access logical connection as an uncontended connection. The open eir NGN Node is a non-blocking device and therefore the Operator may inventory manage the Wholesale Ethernet Interconnect Link to ensure that it is not overbooked, i.e. that the sum of the Wholesale Symmetrical Ethernet Access bandwidths do not exceed the Service Access Bandwidth on the Wholesale Ethernet Interconnect Link (see the Technical Handbook for description of Service Access Bandwidths). In this scenario Quality of Service (QoS) is not required on the Wholesale Symmetrical Ethernet Access as the connection is uncontended and is not carried across the open eir core NGN network (Circuit based CoS Option 5 as described in the Technical Handbook should be specified for these connections). Conversely, the Operator may inventory manage the Wholesale Ethernet Interconnect Link which may result in the Wholesale Ethernet Interconnect Link being overbooked, i.e. that the sum of the Wholesale Symmetrical Ethernet Access bandwidths exceed the Service Access Bandwidth on the Wholesale Ethernet Interconnect Link (see the Technical Handbook for description of Service Access Bandwidths). In this scenario QoS may be required on the Wholesale Symmetrical Ethernet Access and the required level of circuit based class of service should be specified by an Operator. It should be noted that more than one open eir NGN Node may be installed in some serving exchange sites. These open eir NGN Nodes within the same serving exchange site will not be connected locally. 1606/082/2018 Version 5.0 FinalProposed 10

open eir logical level. t is defined both at the physical and the The physical access is the fibre connection from the open eir location to the physical port 3 on the serving open eir NGN node. The open eir network termination point is defined as the User Network Interface (UNI) port. The UNI port is located on the open eir NTU. The open eir (e.g. comms room) for CSH and -location rack in the same exchange as the serving NGN node for IBH. The logical access for IBH is the connection (v - Ethernet Interconnect Link (WEIL). An Operator can associate each WSEA logical with a different WEIL. 1.2 Key Features and Availability The open eir Symmetrical Ethernet Access product provides Operators with the capability to develop their own E-Line and E-LAN type services to meet their end user needs. Key Features: Single mode fibre access connectivity Radial distance fibre reach of 4kms 4 [1000Base-LX] Radial distance fibre reach of 30kms 5 [1000Base-ZX] One WSEA logical access per UNI port (802.1Q trunk) on an open eir NTU 6 One S-VLAN per WSEA logical access Modular bandwidth growth steps Maximum frame size 9000 bytes One Wholesale Symmetrical Ethernet Access (physical access) per NTU C-VLAN ID preservation Class of Service options: Circuit based Traffic based Each Wholesale Symmetrical Ethernet Access (logical) must be associated with an Operator WEIL and associated SAB (existing or new 7 ) 3 From a pricing perspective the physical port is currently included in the logical access 4 1000Base-LX - theoretical maximum distance of 10km actual distances more likely to be 4km is subject to full survey and physical testing 5 1000Base-ZX - theoretical maximum distance of 70km actual distances more likely to be 30km is subject to full survey and physical testing 6 Maximum of five (5) WSEA logical accesses per open eir 1Gb NTU RAD ETX-205A or ETX-202A (for up to 1Gb/s WSEA services) and a max of three (3), (10G) WSEA logical accesses, per open eir NTU RAD ETX-220A (for up to 10Gb/s services). The RAD ETX-220A will also provide up to 10 (1G) logical ports. 1606/082/2018 Version 5.0 FinalProposed 11

Wholesale Symmetrical Ethernet Access is currently available at a number of locations. open eir will circulate and update a rollout plan as open eir continues to extend the Wholesale Symmetrical Ethernet Access reach capability. The rollout plan will be made available to Operators who have signed a Leased Line Agreement for the Wholesale Symmetrical Ethernet Access product. Operators will be requested to formally nominate a designated contact point for receipt of the rollout schedule and associated updates. This will be provided electronically on a monthly basis. The rollout plan will be in workbook format and will detail: Currently deployed locations Planned locations The rollout plan will be e-mailed to the nominated Operator representative The interim 10Gb ALU 7210 SAS-M24F2XFP box, launched on 2 nd May 2014, was withdrawn from selection on new Provide orders on 24 th January 2016 as the new integrated 10Gb RAD ETX220A box has replaced it. 7 Note: If new WEIL, the order must be already placed by open eir and order reference number received and referenced. 1606/082/2018 Version 5.0 FinalProposed 12

2.2 Wholesale Symmetrical Ethernet Access (WSEA) physical access diversity WSEA physical access diversity enables the Operator to order a secondary diverse WSEA physical circuit between the open eir NTU located at the end user site to a physical port on a serving open eir NGN node. An Operator can switch traffic from the primary WSEA physical circuit to the diverse WSEA physical circuit in the event of a fault occurring on the primary WSEA physical circuit. This provides Operators and their end users with a level of access resilience on WSEA physical circuits. The physical access is delivered on a fibre from the open eir network to an Operator POH located at or In-Building Handover for WSEA physical diversity. All WSEA physical access diversity requests are subject to a full site survey prior to order. Following completion of the survey order the Operator will be informed of the results of the survey indicating what diversity options are available. The standard price applies where a open eir owned duct 12 and is within 500 metres of an available open eir access fibre which can connect to the serving open eir NGN Node The standard price does not include the costs associated with (1) installing any new duct or (2) clearing existing duct (3) new duct/poling and/or fibre build work (4) any civil works which may be necessary to establish a connection between the nearest open eir fibre and an Operator premises. All requests are subject to full site survey. - premises is within 500 metres of the NGA fibre cabinet, the standard price will apply where the end - with the exception where bridge, dual carriageway or rail crossings are required where open eir reserves the right to recover any additional costs incurred. For nonopen eir owned duct and is within 500 metres of an available open eir access fibre which can connect to the serving open eir node. open eir reserves the right to recover any additional costs incurred. For the avoidance of doubt, in all cases (NGA and non-nga areas), an Operator is responsible for any costs associated with duct work within their end users own curtilage The same SFP (small form-factor pluggable) type should be installed at both ends of the fibre. There are two diversity options available on WSEA physical circuits. The two options are outlined below: 12 Useable duct for fibre assumes that there is sufficient space in the duct to draw in a subduct 1606/082/2018 Version 5.0 FinalProposed 23

2.2.1 WSEA physical access diversity- Option A Dual NTU/Single NGN Node/Dual Fibre/Dual Duct Two separate WSEA physical circuits are implemented between two open eir NTUs located at the end user site to two physical ports on the same serving open eir NGN node. Both WSEA circuits are active and both fibre strands are located in separate ducts. The Operator controls the failover between the two WSEA physical circuits through the use of Operator CPE which ensures switchover from one WSEA physical circuit to the other in the event of a failure occurring on one WSEA physical circuit. It is the responsibility of the Operator to provide CPE with the relevant functionality which ensures that should a fault occur on either WSEA physical circuit all traffic will be re-routed onto the other WSEA physical circuit.

An Operator, when ordering a CSH Wholesale Symmetrical Ethernet Access, will be required to specify the Service Access Bandwidth (SAB) on their relevant Wholesale Ethernet Interconnect Link (WEIL) to which an Operator wishes to have each WSEA logical connection mapped. An Operator must ensure that their relevant Wholesale Ethernet Interconnect Link (WEIL) and associated Service Access Bandwidth (SAB) are appropriately configured to support Wholesale Symmetrical Ethernet Access (WSEA) connections. An Operator has the capability to manage and prioritise its Wholesale Symmetrical Ethernet Access provided per UNI port on an open eir NTU. Please refer to Appendix 4 (Example 1) for a worked example. 2.2.5 In-Building Handover Logical Connection 1606/082/2018 Version 5.0 FinalProposed 26

The logical connection preserves C-VLAN (if present) from the UNI and presents it on an Operator WEIL at the Point of Handover where 802.1Q support is provided on the open eir NTU. An Operator, when ordering WSEA IBH, will be required to specify the relevant Service Access Bandwidth (SAB) on the relevant Operator Wholesale Ethernet Interconnect Link (WEIL) to which an Operator wishes to have the logical connection mapped. An Operator must ensure that their Wholesale Ethernet Interconnect Link (WEIL) and associated Service Access Bandwidth (SAB) are appropriately configured to support Wholesale Symmetrical Ethernet Access (WSEA) connections. An Operator has the capability to manage and prioritise its Wholesale Symmetrical Ethernet Access provided per UNI port on an open eir NTU. Please refer to Appendix 4 (Example 1) for a worked example. 2.2.6 Automatic Failover to Alternative WEIL. WES failover provides the ability to protect a WES with a pre-provisioned secondary WES homed to an alternative WEIL. In the event of a failure of the active WEIL the associated WES will then be automatically switched to a redundant EIL over a secondary service. (See Appendix 6 for further information) 2.3 Class of Service The Operator end user traffic can be marked as circuit based or traffic based CoS. Class of Service utilises two defined values that determine how the traffic will be prioritised and delivered. These are: Committed Information Rate (CIR) This is the maximum capacity of the bandwidth selected for the end user site that will be guaranteed to be delivered. Peak Information Rate (PIR) This is the maximum capacity of burstable traffic which is capable of being delivered. The difference between the PIR and CIR is referred to as Excess Information Rate (EIR) and there is a possibility that this traffic may be dropped in the open eir network. open eir guarantees that the Committed Information Rate selected by an Operator will be transmitted across the open eir specific network queues (Expedited Forwarding [EF], Assured Forwarding [AF], Standard). This is used to prioritise traffic within the end user access and then map to core open eir network queues to allow for an end to end Class of Service. the Operator WEIL and SAB where the end user traffic is to be delivered and to manage the capacity of their WEIL and associated parameters. 1606/082/2018 Version 5.0 FinalProposed 27

2.3.1 Circuit based Class of Service access basis. The traffic is mapped into the open eir core network queues based on the Class of Service selected. open eir across the open eir core network transparently, therefore preserving an Operator/end user traffic classification (C-VLAN preservation). open eir will apply the Class of Service requested by an Operator on the Wholesale Symmetrical Ethernet Access logical access to all traffic on the logical connection (via the UNI port). Only one Class of Service can be applied to each Wholesale Symmetrical Ethernet Access logical access at a time. Table 3 outlines the six different circuit based Class of Service options offered by open eir. The percentage values in this table refer to the percentage of the bandwidth selected by the Operator for that end user site. The maximum class of service bandwidth column in this table details the maximum bandwidth that can be ordered for the end user access based on the circuit based Class of Service option selected i.e. if a circuit based Class of Service option 1 has been selected the maximum bandwidth that can be ordered is 1000Mb/s (1Gb/s) on a 1Gb SEA and 3000Mb/s (3Gb/s) on a 10Gb SEA. Please refer to Appendix 2 for worked examples of circuit based Class of Service. 1606/082/2018 Version 5.0 FinalProposed 28

Notes regarding APT sites 100% AF or less, up to and including 600Mb/s, is available at all location, with the exception of 1Gb APT Nodes where the limit is 300 Mb/s and at 10Gb APT Nodes the limit is 1Gb. 1606/082/2018 Version 5.0 FinalProposed 31

At APT nodes where a customer is moved to a dedicated fibre the Class of Service Bandwidth with a CIR of 100% AF or less, up to and including 6Gb/s and 3Gb/s EF may be available and is determined on a site by site basis. The A percentage value in the table above refers to the CIR for the EF queue. For EF traffic, the CIR value equals the PIR value and hence EF traffic will not be allowed to burst above the A percentage value specified above for a Wholesale Symmetrical Ethernet Access connection. The B percentage value in the table above refers to the CIR for the AF queue. For AF traffic the PIR value equals the bandwidth specified for the Wholesale Symmetrical Ethernet Access connection. Therefore AF traffic can burst up to the maximum bandwidth of the Wholesale Symmetrical Ethernet Access connection but only the B % value specified in the table above will be committed bandwidth. Standard traffic can burst up to the maximum bandwidth of the Wholesale Symmetrical Ethernet Access connection. There is no CIR associated with the Standard queue. It is important to note that the sum of the A % and B % cannot exceed 95% of the relevant Wholesale Symmetrical Ethernet Access bandwidth. The A percentage and B percentage must be expressed in percentage increments as follows: Percentage EF/AF Mix Increment 1-5% EF only 1% 5% EF and AF 10-20% EF and AF 10% 25% Fixed option EF=50% AF=25% 30-50% EF and AF 10% 55% Fixed option EF=20% AF=55% 55% EF only 60-70% EF and AF 10% 75% Fixed option EF=0% AF=75% 80-90% EF and AF 10% 95% Fixed option EF=95% AF=0% Table 5: EF and AF Percentage See Appendix 5 for details of the available permutations. 1606/082/2018 Version 5.0 FinalProposed 32

See the process manual section on Quotations for further details. All WSEA physical access diversity requests are subject to a full site survey. The results of the survey detail what diversity options are available to the Operator and the price of each option. 4.3 Ordering, Provisioning and Assurance The Ordering, Provisioning and Maintenance processes will be supported by the Unified Gateway (UG) which will be used to log orders and report faults for the product via the UG web GUI. The UG is an order management and fault handling system designed to be the primary interface between open eir and an Operator. Operators will be able to enter all the necessary data via structured on line screens for both ordering and fault reporting. Once all the data has been entered an order or fault can be submitted. The UG will accept and validate the relevant orders and faults and will provide appropriate notifications in response. Order and fault status updates through to completion will then be provided back to the Operator and can be viewed via the order and fault tracking screens. Service assurance on a fibre provided for an Operator on a WSEA IBH, will be provided by open eir, It is the responsibility of an Operator to prove any fault from an Operator network to the point of handover (POH). If the fibre cable needs to be replaced, it will be funded by an Operator. 4.3.1 Ordering the Service An Operator may place an order for the product via the Unified Gateway 13. There are a number of product rules that the Operator must observe before requesting the service: Order for the Wholesale Ethernet Interconnect Link (including Service Access Bandwidth) must either be ordered or delivered An Operator must nominate the relevant Service Access Bandwidth via the open eir circuit reference to which the end customer traffic shall be connected An Operator is responsible to ensure that by ordering these they do not: breach the rules of the WEIL exceed the WSEA physical capacity exceed the WSEA maximum Class of Service rules An Operator should check that the Service Access Bandwidth nominated to map the end customer traffic to, has suitable settings to support the requested bandwidth and Class of Service 13 Orders for additional WSEA logical accesses, must be placed via the open eir manual order form see the WSEA Industry Process Manual for further details. 1606/082/2018 Version 5.0 FinalProposed 36

For WSEA physical access diversity circuits a survey must have been completed prior to ordering. The survey reference number must be referenced in the relevant input field when placing the order. A WSEA CSH order will provide connectivity from the Operators end customer premises to the open eir network. The physical order will require the installation of fibre and an NTU at the Operator end customer premises. Once the physical delivery is completed the logical component shall be delivered, which will include logical test results within the welcome pack. This element of the order enables provision of the logical component according to the CoS and bandwidth nominated by the Operator, and references both the WSEA physical and nominated SAB to which the service is to be delivered. A WSEA IBH order will provide connectivity from the open eir - Building Handover point located within an open eir exchange. The WSEA physical connectivity will require preparation and installation of open eir fibre and equipment within the same open eir exchange as the serving open eir NGN Node. Before placing the order on the UG an Operator must have a Co-location footprint in place in compliance with the Process Manual for open eir Physical Co-location Service. On request, (QIB Order Type) open eir will undertake to assess the work that is required to prepare the open eir exchange facility for an In-Building Handover and provide a quotation for an Operator for the WSEA. open eir will install (PIB Order Type) the physical connectivity of the WSEA from the POH to the open eir NGN Node within the same open eir exchange in line with the order for the WSEA.

Appendix 1 NTU Specification (legacy) 1. Details ers: orders. These older NTU do not support handover testing of logical circuits. For handover testing to operate the logical service (WES) must terminate on either a RAD ETX205A and/or RAD ETX220A at the WSEA and WEIL location. 1.1 NTU Type: RAD ETX-202A for up to 1Gb WSEA services This NTU model was available for selection on new Provide (PDC) orders between 2010 and 24 th January 2016. From 25 th January 2016 the RAD ETX-202A was no longer available and has been replaced by a more suitable NTU type. The RAD ETX 202A (AP-1 below) was used for <=1Gb services only. It has one port (port 1) reserved for open eir network connectivity and one optical (port 2) and four electrical ports (ports 3-6) are available for Operator use to terminate WSEA logical accesses at the Operator end user site on an open eir NTU. If an Operator requires either different combinations of interface presentation types on the NTU or more logical services on the WSEA than the ETX-202A NTU(s) can support please contact your Account Manager to discuss alternative NTU solutions. The Operator can specify either a fibre or copper port to handoff the product. Each port is referred to as the User Network Interface (UNI) port and is configured as a 802.1Q port.

These CoS options and speeds are available at certain NGN / Reach Nodes only. See the latest version of the NGN Rollout plan for a list of these locations. 1606/082/2018 Version 5.0 FinalProposed 58

Appendix 6 WEIL Automatic Failover to Alternative In the event of a primary WEIL failure openeir have developed an automated failover solution for a WES to failover to a secondary WEIL This is enabled by created a second logical WES to the alternative WEIL This second logical WES has all the attributes of the primary WES with the exception of EIL, SAB and s-vlan id WES failover provides the ability to protect a WES with a pre-provisioned secondary WES homed to an alternative WEIL. In the event of a failure of the activew EIL the associated WES will then be automatically switched to a redundant EIL over a secondary service. This failover takes approx. 90ms. The failure conditions that will instigate a WES switch from primaryweil to its secondary can be defined as follows. Fibre cut or node failure on the primary WEIL resulting in an mpls error flag getting forwarded to the SEA WES. Network connectivity fault resulting in the primary WES going to an operationally down state instigating a switch to the standby WES. service band active and standby service. The operator can then implement redundancy using the following two approaches: active standby or active active. an 1606/082/2018 Version 5.0 FinalProposed 59

Some criteria around diversity will need to be enforced, WEIL resilience will only be allowed in the following scenarios: 1. Main Active WES is SNN then resilience RES must also be SNN (but on a different agg. node) 2. Main Active WES is SNR then resilience RES must also be SNR or SNN 3. Main Active WES is DR then resilience RES must also be DR or SNR or SNN 1606/082/2018 Version 5.0 FinalProposed 60
