EUROPEAN ANALOG TELECOM MEASUREMENT SERVICES

Communication Certification Laboratory

offers measurement services to the European Analog Telecom Specifications. Manufacturers of analog telecom equipment are finally able to have their products tested in the United States.

The PACT (PSTN Access Conformance Tester),

used by CCL, is a complete and modern conformance test system using the latest in measurement technology. The system was developed in Europe by CETECOM, to perform testing to European Analog Technical Specifications.

 

European Analog Standards

Communication Certification Laboratory offers measurement services for the following European Telecommunications - Analog Standards:

ETSI Standards
TBR21	PSTN access requirements for non-voice TE
TBR38	Acoustics Testing

TBR 38. This TBR specifies the technical characteristics (electrical and acoustic requirements) under Article 4(g) of Directive 91/263/EEC to be provided by a single, handset telephony, terminal equipment which is intended: (a) for pan-European approval; and (b) for connection by 2-wires to an analogue interface of a PSTN. This interface is characterized by a d.c. loop to indicate seizure and clearing, low frequency a.c. ringing signals below the speech pass band to indicate an incoming call and in the transmission phase has a approximate bandwidth of 3 kHz at the network termination point; and (c) for supporting the voice telephony justified case service.

TBR 21. This TBR is for Terminal Equipment (TE); Attachment requirements for pan-European approval for connection to the analogue Public Switched Telephone Networks (PSTNs) of TE (excluding TE supporting the voice telephony service) in which network addressing, if provided, is by means of Dual Tone Multi Frequency (DTMF) signaling.
