EN 300 386 V1.3.2 (2003-05) Electromagnetic compatibility and Radio spectrum Matters (ERM); Telecommunication network equipment; ElectroMagnetic Compatibility (EMC) requirements

The purpose of this standard is to measure the EMC requirements for equipment intended to be used within a telecommunications network (as defined in clause 3). Examples of such equipment are:
  1. Switching equipment, such equipment includes:
    • local telephone exchanges
    • remote switching concentrators
    • international switches
    • telex switches
    • network packet switches
General purpose equipment, which is used as a part of a switching system, may be covered by the scope of other standards. For such equipment, if those other standards fully cover all the requirements of the present document, no further requirements are necessary. Switching equipment can also contain transmission functions, and this has to be recognized during testing.
  1. Non-radio transmission equipment and ancillary equipment. Such equipment includes:
    • multiplexers
    • line equipment and repeaters, e.g. equipment for:
      • Synchronous Digital Hierarchy (SDH)
      • Plesiochronous Digital Hierarchy (PDH)
      • Asynchronous Transfer Mode (ATM) Such as:
      • Digital Cross Connect systems
      • network terminations
      • transmission equipment used in the access network like XDSL
  2. Power supply equipment. Such equipment includes
    • central power plant
    • end of suite power supplies
    • uninterruptible power supplies
    • stabilized AC power supplies
    • other dedicated telecommunication network power supplies; but excludes equipment which is uniquely associated with or integrated in other equipment
  3. Supervisory equipment, such equipment includes:
    • network management equipment
    • operator access maintenance equipment
    • traffic measurement systems
    • line test units
    • functional test units
The function of supervision may either be performed by independent equipment or form part of other telecommunication equipment. If the function of supervision forms part of telecommunication equipment, the performance may be evaluated simultaneously with other functions (such as switching and transmission) during EMC testing.
