AuroraForteA powerful tool for testing the Physical, ATM and IP layer operation of ATM circuits. Provides IMA, E1, E3, DS1, DS3, ATM25, STM1/OC3 and STM4/OC12 interfaces for unparalleled multi-circuit testing ATM, xDSL and 3G networks. Physical and ATM BER testing. Advanced features, AAL5, OAM, QoS, SVC support and IP Ping over ATM, protocol decoding and remote testing, analysis of IP traffic composition.

VictoriaSDH/ATM/IPFamily of testers that combine IP, ATM and SDH capabilities up to 2.5 Gbit/s. Transmission functions include TCM, APS, M/N alarms, G.783 sequences, frequency deviation and nx64 and Nx56kbit/s tests at E1 and DS1 levels. ATM features include generation and analysis of ATM flows,QoS, OAM flows, generation/analysis AAL1/2/5, and also provides analysis of IP traffic composition.

VictoriaJitter/WanderA cost-effective solution that provides complete loop fault management for Control Centres that support a large number of xDSL installations. Its remote testing capacities include: emulation of equipment at both central offices and customer premises, TDR, DMM, an extensive range of ana-logue measurements, spectrum analysis, ATM, PPP, IP and higher level protocol test.
