Toshiba Adtran 1550 Switch Support Bulletin

A Toshiba product bulletin from April 2016 about Toshiba business phone systems. It runs 3 pages. Toshiba used bulletins to tell dealers and customers about new releases, hardware, compatibility and changes in support, so they're a reliable record of what a given release or product actually included.

Toshiba closed its phone-system division in 2017, but its phones and systems are still widely used, and our certified Toshiba technicians support them remotely and onsite.
