93 Annex 1 Specifications for products as found in the previously available RDSLO Offer This annex features an abridged version of the basic technical and financial specifications for the formerly available products and services of the RDSLO (Reference DSL Offer). New products and services with these specifications will be available during a transitional period of 3 months after the entry into force of the ROB. Support for existing services or services purchased during the transitional phase will be provided according to the terms and conditions laid down for Bitstream Services in Schedule 4 - Fault Repair and Reporting and Schedule 5 - Service Level Agreement of the ROB.

95 1. Service Description - Connect IP The Connect IP Service allows the Operator to connect to EPT s DSL Network. Therefore, an IP interconnection is established with the EPT s platform aggregating the DSL Access lines. Within the scope of the RDSLO two scenarios are possible depending which xdsl service is used Transport of HSI traffic for standard, professional and VDSL services Description Connect IP Service uses L2TP tunnelling between EPT s BRAS and the Operator s tunnelling termination equipment. The tunnels are initiated by EPT s BRAS(s), which ensure(s) the LAC (L2TP Access Concentrator) function. The equipment(s) of the Operator are terminating the tunnels and ensure as such the function of the LNS (L2TP Network Server). The Connect IP Service offered by EPT covers the Ethernet interface on EPT s BRAS, as well as the routing of the traffic of the Operator s End Users from the BRAS to the said interface (POI). All Operators DSL access lines can be reached via one single Connect IP service. This is independent from the number of BRAS(s) used by EPT within its DSL Network. The necessary routing between the different BRAS(s) lies under EPT s responsibility. The following bandwidths are available: Total bandwidth of the Connect IP Service Interface 100 Mbit/s FastEthernet 200 Mbit/s GbitEthernet 400 Mbit/s GbitEthernet 700 Mbit/s GbitEthernet 1 Gbit/s GbitEthernet Reference Offer for Broadband Services (ROB) Version Annex 1 : RDSLO 3/15

The necessary IP-addresses used to establish the IP connectivity between End User s Active Equipment and the Operator s tunnelling terminating equipment are provided and owned by the Operator. Via the said Connect IP access, a L2TP tunnel is established via an internal EPT trunking from each EPT s BRAS to the Operator.

For each DSLAM one VLAN is available (Point 1 to Point 2). The identification of each VLAN is done by the S-TAG, the C-TAG is for identification of the service, in this case VoE. For a VLAN between the ConnectIP demarcation point and each DSLAM a bandwidth of 3 Mbit/s is offered by default. Packets exceeding this limit will be rejected by EPT s network. However, based on justified reasons, the Operator can require additional bandwidth for those VLANs. The overall capacity ordered at the Connect IP demarcation point (Point 3) is thus divided into two streams: (i) a VLAN for HSI traffic, (best effort quality), and (ii) one stream for VoE traffic (regrouping all VLANs VoE between the DSLAMs and the ConnectIP demarcation Point with priority bit). With the Order fir the ConnectIP the Operator has to specify the capacity required for HSI traffic as well as the total needed traffic for VoE at Point 3. a i The ordered VoE capacity may differ from the sum of all VoE-VLANs (å ) In case of violation of the defined service parameters for the VLANs VoE, EPT will apply policing as defined by the MEF 1. The Operator has thus to guarantee that his IP-streams fulfill the defined service parameters. The configuration of the VLANs VoE between the ConnectIP demarcation point and the DSLAMs (Point 1 and Point 2) is as follows: 1 (last access ) Reference Offer for Broadband Services (ROB) Version Annex 1 : RDSLO 5/15
