The Cellular Card Phone RPE-1 is a GSM class 5 compatible cellular phone without a battery or user interface of its own. Instead, the device is computer controlled through the 68-pin PCMCIA connector. This connector is used to:

- 1) supply the card with all operating power it needs

- 2) transfer operating commands and their responses,

- 3) transfer digitized speech or GSM data and control messages and

- 4) during production or servicing transfer tuning parameters and FLASH download data.

Physically the RPE-1 is compatible with the PC Card '95 standard (and earlier PCMCIA standard) for type II extended cards.
