AT&T Technologies Power Module 1

The AT&T Power Module 1 is a legacy power adapter originally designed for telecommunications equipment. This specific model, often associated with part numbers like 104200118 or Model 3301A, was historically used to power telephone systems and network interface units provided by AT&T. While labeled as 'AT&T Technologies,' this division was a key part of the American Bell System before various corporate restructurings.

Today, the AT&T brand is managed by AT&T Inc., which remains a global leader in telecommunications. Most contemporary power modules and similar electronic accessories under this brand are manufactured in China through contract manufacturing partnerships. The product reflects the long-standing history of AT&T's involvement in both the infrastructure and the hardware of the communications industry, spanning from the early days of Western Electric to modern fiber-optic network components.
