Abstract: A PCMCIA card for use in electronic equipment includes a glass laminate circuit board including a pair of substantially planar, oppositely disposed component-mounting surfaces. Printed circuitry is designed and arranged on at least one of the component-mounting surfaces. At least one integrated circuit package is assembled onto the printed circuitry and has a length dimension direction and a shorter, width dimension direction. In order to reduce the stresses which the integrated circuit package is subjected to during handling of the PCMCIA card, the integrated circuit package is arranged on the circuit board such that the integrated circuit package length dimension direction is substantially parallel to the width dimension direction of a cooperating metal case which is part of the PCMCIA card. The assembled circuit board is encapsulated with a flexible potting compound and enclosed within the metal case to complete the PCMCIA card assembly.

Abstract: A special services add-on specifically adapted for use in a dial pulse activated telephone switching office such as a step-by-step office to enable the addition of various modern features thereto, thereby extending the economic life of the office. The add-on is a stored program, processor based system that can be put into service on a line-by-line basis independent of subscriber line assignments. Among the special services provided by the add-on are incoming call alert, call conferencing, call forwarding, tone dialing, abbreviated dialing, instant recall, restricted calling, ringback, delayed ringback and ring disable. Various of the services are remotely controllable by the subscriber by dialing programming instructions to the add-on either from his own or another telephone subset.
