ISDN/CAS Testers

Linkbit products allow to run ISDN and CAS simulation and load generation tests over multiple full-duplex E1/T1 spans. Multiple signaling links and voice circuits are supported. Linkbit also supports all major CAS variants. Sigtran IUA and DUA adaptation layers are supported for converging networks.

Major ISDN protocols supported

EDSS1, NI-2, DPNSS/DASS2, 5ESS, DMS100, IUA, DUA

Major CAS protocols supported

R2 MF, R2 MFC, R2 DTMF, E & M, Wink, Loop Start, Ground Start, National R2 variants

Software Capabilities

Linkbit Simulation Studio allows to easily implement functional, load and conformance tests for ISDN protocols and networks. It allows to create tests of virtually unlimied flexibility for the protocol signalung and media paths. Linkbit Message Sequencer fully automates creation and test of message sequences. Linkbit Message Wizard allows to build any message, layer by layer, with a sequence of point and clicks.

Instant import, point-and-click edit and replay of Pcap trace logs provides a unique testing capability. Linkbit Simulation Studio seamless integration of well known scripting engines (Perl, Pythin, PHP, Jscript, VBasic) delivers the capability to build tests of any complexity.

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

ISDN PRI Load Generation

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