Communications test equipment maker ikon GmbH is preparing to offer a communications tester targeting next-generation UMTS Node B (Universal Mobile Telecommunications System) modules. When it becomes available, the test set will focus on the Transport Layer, in accordance with the OBSAI (Open Base Station Standard Initiative) architecture.

iKon's tester will be based on a Linux-operating system workstation (a standard PC) that's equipped with four ATM (E1) and four Fast Ethernet interfaces (in its default configuration).

The tester can be operated via a GUI (graphical user interface), or automatically via a built-in command-line interface.

In use, tests cover statically-configured connections as well as signaled connections using AAL-2 Signaling (Q.2630), and IP Connection Control Signaling (Q.2631). Besides several signaling tests, emphasis is placed on data tests over ATM AAL0/2/5 and TCP/UDP. Parameters such as correct mapping, data integrity, correct sequence, and latency are checked. Using the system's GUI, various test scenarios can be configured and run automatically.

Future extensions

ikon also plans extensions to this system, such as RNC simulation or the support of ATM OC3/STM-1, and Gigabit Ethernet interfaces. In addition, user-specific extension can be integrated at any time.

ikon says it will also eventually offer extensions supporting ISDN and VoIP.

At press time, the company hadn't finished writing the datasheet for this product, nor has it supplied pricing information. Consider it a work-in-progress.
