1. Foundation and Scope
1.1 Foundation
The specification is issued pursuant to paragraph 1 of Article 42 of the Telecommunications Acts.
1.2 Scope
An S-PCN MES may be a handheld, portable, vehicle-mounted, host connected, semi-fixed or fixed equipment, or may be an element in a multi-mode terminal. It may consist of a number of modules with associated connections and user interface, or may be a self contained single unit.
If the MES is an element in a multi-mode terminal, unless otherwise stated in this Guidelines, its requirements apply only to the S-PCN MES element of the terminal operating in one or more of the MSS frequency bands given in table 1.
1.3 Contents and Reference
The guidelines regulation are based on "Compliance Approval Regulations of Telecommunications Terminal Equipment", including the test items, standards, methods, related technical requirements, and considering the specialty of globalization and internationalization of satellite mobile communications.
In order to meet international standards, we will comply the related regulations of ETSI TBR 41's latest version and take it as reference for making our regulations perfect.
