A method that allows trimming glass comprising a hydrophobic andor oil-repellent surface coating, where a temporary protective layer is coated on the surface of said glass and the temporary protective layer imparts to the glass a surface energy of at least 15 mJm2. The method may be modified to operate in UM mode or AM mode and to transmit data over one of several radio bearers. The multiple issue pipeline is scaleable to greater parallel issue of packets, and tunable to differing switch engine architectures, differing interface speeds and widths, and differing clock rates and buffer sizes.
