ISDN/CAS Testers

Linkbit products allow to create and run ISDN and CAS functional, conformance, fuzzing, security, QoS and load generation tests. Multiple signaling links and voice circuits are supported. All major PRI and CAS variants are supported. Sigtran IUA and DUA adaptation layers are supported for converging networks.

Protocols supported

EDSS1, NI-2, DPNSS/DASS2, 5ESS, DMS100, IUA, DUA, R2 MF, R2 MFC, R2 DTMF, E & M, Wink, Loop Start, Ground Start, National R2 variants

Software Capabilities

Linkbit Simulation Studio allows to implement PRI testing on per packet basis. Any supported PRI message, or a message flow can be generated very quickly. Direct access to HDLC stream allow to send packets of any data contents and lenght.

CAS Interregister and Linear Signaling state machines can be graphically edited for adaptation to national variants of CAS protocols.

ISDN PRI Load Generation

Linkbit allows to fully load multiple D/B-channels over multiple E1 spans.
