WLR3 ISDN2e
Offer your own-branded phone services over our digital network with Wholesale Digital Access (WLR3) Integrated Services Digital Network (ISDN2e).
We provide, maintain and repair the ISDN2e lines, while you set the prices and bill your customers directly.
How it works
We digitally transmit voice calls and data over ordinary copper phone wires. There are two options: ISDN Standard and ISDN System. Both give you the flexibility of numbering and channel configuration to meet your customers’ needs. Even in its simplest two-channel configuration (i.e. Standard), a single WLR3 ISDN2e line can integrate everything a small office or home-based business needs at the desktop – computer, phone and internet access.
ISDN Standard and ISDN System are also both access products. That means they give you the option to carry calls via the Openreach network and carrier pre select (CPS) or indirect access networks. The calls package provider will then charge your customers for calls.

How-to guides for using Openreach products.
Information on what happens when you order a product or raise a fault with us. You’ll also find links to documents like product descriptions, pricing information and contracts.
The following documents explain the functional changes and upgrades we’ve made with each release, and how they affect the way our system interacts with yours.
They’re aimed at your technical teams who design and build interfaces into the Openreach B2B gateway.
When we’re going to make a change, we’ll create a new document which we’ll publish before testing or release. We’ll then update this if we need to, based on our findings. So keep checking back for updates.
(We reserve the right to change functionality as part of a release, and to add a new document to reflect this.)
We have a standardised process which we use to tell you about product releases. It’s called external information points (EIP). Find out more.
You can now find Functional Specification, and B2B/XML Release Documentation on iPublish, which can be found within the 'Your tools' section on your Dashboard.
