Below is a picture of the printed circuit board of the PP-00, a Primary Rate ISDN E1/T1 adapter with PCI Interface. This design is quite special since it was designed and manufactured from scratch in just below 5 weeks. It is designed with the future availibility of components in the back of the mind. Both an ISDN stack and Windows NT 4.0 drivers are available for special E1/T1 projects. Move with your mouse over the picture for in-depth information.
