The 2852 and 2853 are able to generate and receive all commonly used framing systems up to 34 Mbit/s, for both the European and North American digital hierarchies.
The instrument can be optioned as European or hybrid versions, and this includes an all bit rate version (European plus North American). Thus 2852 and 2853 have the flexibility to address global applications, including operation in International Gateways where there is a requirement to test mixtures of European and North American traffic carried on satellite systems.
