These Regulations are promulgated pursuant to Paragraph 3, Article 44 of the Telecommunications Management Act.

The terms adopted in these Regulations are defined as follows:
1. Telecommunications terminal equipment（hereinafter as “TTE”）: a piece of equipment that interfaces with public telecommunications network at a terminal point using wireless or wired transmission media and communicates via light or electromagnetic waves.
2. Testing body: a testing laboratory approved by a domestic accreditation body as approved by the competent authority to comply with CNS 17025 or ISO/IEC 17025.
3. Certification body: the competent authority or an institute delegated by the competent authority for the reviews of TTE.
4. Series product: a piece of TTE or non-plug-and-play restricted communications module that is qualified in review without any change to the product in the original application and meets either of the following:
（1）No change to techniques used, such as power output, modulation technique, working frequency, number of channels and layout of circuit board containing major elements, with change（s）only to antenna, appearance, color, material, associated non-telecommunications functions, power supply, accessory, brand or model, and the product with the same basic design and functions for telecommunications interface, electromagnetic compatibility and electrical safety;
（2）No change to telecommunications hardware with change（s）only to modulation technique by firmware or software, reduction of power output, frequency range, bandwidth or number of channels.
5. Non-plug-and-play restricted communications module: a wireless transmitter, wireless transceiver or wired transmission or receiving module that is provided with complete telecommunications interface functionality but unable to operate independently;
6. Platform: a piece of equipment that is fully functional even without a non-plug-and-play restricted communications module.
7. Final product: a piece of TTE assembled from a non-plug-and-play restricted communications module and a platform.
8. Approval certificate: a type approval certificate, declaration of compliance certificate, simplified declaration of compliance certificate or compliance approval certificate issued according to these Regulations.
9. Accessory: a signal cable or equipment connected to TTE or non-plug-and-play restricted communications module for normal use.
10. Peripheral: a piece of equipment connected to TTE or non-plug-and-play restricted communications module for normal use.
11. Test cable: a cable connected to TTE or non-plug-and-play restricted communications module for the purpose of testing.
12. Test fixture: a piece of equipment attached to TTE or non-plug-and-play restricted communications module for the purpose of testing.
13. Personal locator beacon（PLB）: a piece of equipment that transmits a distress signal at 406 MHz, or together with an auxiliary signal at 121.5 MHz, to a satellite in real time for the purpose of rescue when an individual is stranded.

TTE shall comply with the technical specifications established by the competent authority; for those for which the competent authority has not yet established the technical specifications, the following shall apply in the following order of priority:
1. Chinese National Standards（CNS）;
2. Standards established by an international standardization organization;
3. Standards established by a regional standardization organization.
For the criteria of electromagnetic compatibility or electrical safety in the technical specifications mentioned above, the requirements specified in other laws and regulations shall apply.

Regarding the TTE connected to a piece of telecommunications equipment established by a telecommunications enterprise operating a public telecommunications network, in the case where additional test items are required in order to comply with the conditions of connection, the approval of the competent authority shall be required in addition to compliance with the applicable technical specifications mentioned in the preceding article.
