An impedance matching network extends the analogue outputs for POTS testing, covering the international network requirements. Functional extension for measuring longitudinal balance completes the POTS testing requests. The ability to extend RT-2X with ISDN basic rate and E1/T1/J1 primary rate interfaces promotes the RT-2X to be a truely dual-domain Telecommunications analyzer, conducting all TX and RX tests (A-A, A-D, D-D, D-A). RT-2X is the complete test solution to verify the analog parameters of e.g. linecards with analog POTS- and digital T1, E1 or J1 access interfaces.
It exceeds the functionality of the discontinued W&G PCM4 by far. RT-2X offers the full and uncompromised RT-2M functionality in a larger cabinet to inlcude additional telecomunication testing options.
