Proximus Reference Offer for Bitstream xDSL Access

A regulated offer that enables wholesale customers to offer data access services to their end-users, using the fixed copper network of Proximus

Your network is linked to the Proximus network in specific Access Points, from where your data traffic is carried over the Proximus Ethernet network to the local exchange where you are connected. In function of your requirements, Proximus shapes an xDSL (ADSL, ADSL2+, Re-ADSL2 or VDSL2) signal on the local lines to your end-users.

The conditions for providing Bitstream xDSL services are set out in the Proximus Reference Offer for Bitstream xDSL Access.

Regulated offer

The version 4 of the Proximus Reference Offer has been approved by BIPT on 17/02/2023 and is published here below.

Key features

The Welcome Pack explains how a new operator can implement the Bitstream xDSL offer and deliver its first end-user lines.


The Bistream xDSL offer consists of various building blocks to deliver data access to the end-users


The OAL (OLO Access Line) is the connection between Proximus’s network and the OLO’s network. The network is divided into 5 areas and approximately 600 local networks. There are two PoPs per area and one LEX per local network. The OLO must order an OAL in a Proximus Service PoP or a LEX to provide data access to the end-users of the corresponding area.

Ethernet Transport

Between the LEX where the OLO wants to be active and the OAL, data are carried on Proximus Ethernet network through VLANs. When ordering VLANs, the OLO can choose between 4 service qualities and two VLAN options (Shared or Dedicated VLAN). With Shared VLAN, the data from the end-users will be bundled in 4 VLANs (one per service quality). With Dedicated VLAN, a specific VLAN will be created to bundle all the traffic from each specific end-user.

End-user lines

The end-user line is the link between the DSLAM (situated in the LEX or in a ROP - Remote Optical Platform) and the end-user. It uses one of the available xDSL technologies to provide a fast end-user access on Proximus copper pairs. The access speed depends on the distance and quality of the copper pair between the end-user and the DSLAM or ROP.


The VDSL2 technology requires a specific configuration of the CPE (modem). Therefore, only CPEs provided by Proximus or CPEs specifically tested for Proximus network will be accepted.
