Ericsson

Ericsson is a Swedish maker of telecommunications equipment, founded in Stockholm in 1876 by Lars Magnus Ericsson. Today it focuses on mobile network infrastructure, but for decades it also built enterprise telephone systems such as the MD110 and MX-ONE. Aastra took over Ericsson's enterprise communications business in 2008, so many older PBX boards carry both names. Seven Star LLC sources and supplies these Ericsson boards for sites in Oman and the GCC that still run such exchanges.

Ericsson telephone exchange boards listed

Two boards are on this page. The ELU34 is an analog extension board of the MX-ONE exchange family, the card that connects ordinary analog telephones to the exchange. The MGU card, listed as 2X4E1/T1 under the names Aastra and Ericsson, provides E1/T1 trunk connections. Both are spare parts for existing systems, not new network equipment.

Ordering Ericsson boards: what we need

These boards are identified by a product number printed on the front strip or on a label, typically in the form ROF followed by digits, with a revision state such as R2A. Send both, since a board name like ELU34 can cover more than one revision. Tell us the exchange type and software release, the slot the board comes from, and whether the name on the faulty board is Ericsson or Aastra. Photos of the board front and label help.

Frequently Asked Questions

How do I identify an Ericsson exchange board?
Each board has a functional name, such as ELU34 or MGU, and a product number with a revision state. The functional name says what the board does. The product number and revision say exactly which hardware it is. Copy all of them from the board front and label, or send a clear photo.
The board in our exchange says Aastra, not Ericsson. Is it the same part?
The MGU card on this page is listed under both names, and boards for these exchanges were supplied with either name on the label. What decides compatibility is the product number and revision, not the logo. Send those details and we check them against the documentation for your system.
Will a board with a different revision work?
It may or may not. Compatibility between revisions depends on the software release of the exchange. We do not assume it. Send the revision of the board you have and the release your system runs, and we look for the same revision first, then for one the system documentation accepts.
Why are Ericsson PBX boards also labelled Aastra?
Aastra took over Ericsson's enterprise communications business, including the MD110 and MX-ONE systems, in 2008. Boards made before and after that date may carry either name and are often interchangeable.
Is Seven Star LLC a distributor of Ericsson?
No. Seven Star LLC is an independent supplier with no distributor or agency relationship with Ericsson. We source these boards through commercial channels by product number and provide the documentation that the source issues with the item, on request, so you can check it.
