KlasHopper M4 – the premium ISDN card for M4 satellite phones

KlasHopper M4 is an ISDN card specifically designed to support satellite and terrestrial ISDN networks. The KlasHopper M4 is easy to install on any Windows PC and is optimised to give excellent throughput. Two KlasHopper M4 cards installed in a PC can support two M4 satellite calls giving users the option of combining satellite channels and doubling the available bandwidth. KlasHopper is available in both PCI and PCMCIA format and supports Windows 95/98, Windows Me, Windows NT 4.0 Windows 2000 and Windows XP.

Details:
Tested with all M4 terminals KlasHopper M4 support Euro-ISDN as default and has been tested with the leading single-channel (64K) and dual-channel (128K) M4 terminals: Nera World Communicator, Thrane & Thrane Capsat Messenger, MTI 128K and O’GARA E-Lite.

Support:
Klas offer free technical support for all KlasHopper M4 users. We are conversant in all satellite issues including the effect of satellite transit delay on the performance of standard applications.

Optimization and TCP/IP:
KlasHopper M4 installs two independent dial-up devices which integrate fully into the Windows operating system. This means that they use the built-in TCP/IP stack of Windows which is much easier to optimize for satellite than stand-alone TCP/IP stacks found in routers or external TA’s. For example, Windows 2000/XP have self-tuning TCP/IP stacks that work well over satellite. However, an external TA with its’ own TCP/IP stack can often cancel out the benefits of the Windows self-tuning stack.

Dial and Answer at 128K:
KlasHopper M4 can be configured to dial and answer calls at 128K in all Windows operating systems. Many ISDN TA’s have difficulty answering calls at 128K, especially from M4 terminals.

Full OS Support:
KlasHopper M4 supports all major Windows operating systems including Windows 95/98, Windows Me, Windows NT 4.0, Windows 2000 and Windows XP.
