Aeroflex has announced its 6103 AIME/CT GSM, GPRS, EGPRS mobile terminal protocol test system to include the DTM (Dual Transfer Mode) test cases, a comprehensive suite of DARP (Downlink Advanced Receiver Performance) test cases including three that are the suite of 3GPP Release 4 and EGPRS test cases as defined by the GCF (Global Certification Forum) and PTCRB (PCS Type Certification Review Board). DTM provides the ability to make a circuit-switched connection at the same time as a packet switched connection that enables users to surf the Internet or use applications such as MMS and IMPS at the same time as making a voice call using a single handset. DTM is a standard feature of WCDMA but test cases are needed for EGPRS to ensure a seamless service when moving between 3G and 2G networks. The 6103 AIME/CT supports all the DTM protocol test cases at the GCF that do not also require a WCDMA protocol test system. The DTM test case support on the 6103 AIME/CT is the most comprehensive currently available on any 2.5G mobile terminal protocol test system.
