The Ericsson ROF1575112/1 is a BTU-D (Basic Trunk Unit, Digital), a digital trunk board for Ericsson MD110 and MX-ONE enterprise PBX systems. It provides an ISDN PRI (E1, 30-channel) digital trunk interface, connecting the exchange to the public network or to another PBX over a primary-rate digital line.
The board fits a line-trunk module slot in an MD110 or MX-ONE magazine and handles the signalling and 2 Mbit/s framing for the trunk. It is the base variant of the BTU-D family used across these systems.
As legacy MD110 and MX-ONE hardware it remains in demand for maintaining and expanding installed systems. Available from Tech Star as new or refurbished stock. Submit a price enquiry for availability and lead time.
