teleSys announces general availabilty of the MACH7 iSTP Platform.
San Mateo, California
May 12, 2004

teleSys announces general availability of the MACH7 iSTP platform, which provides unparalleled reliability, capacity and throughput at an exceptional value, with the highest level of performance and network security. The platform supports a variety of value-added feature options, including the following:

• Global Title Translation (GTT)
• Gateway Screening (GS)
• Application Transport Access
• MACH7fe Control Chassis
• High Speed Links (HSL)

The Global Title Translation feature provides support for the signaling connection control part (SCCP) of the ANSI and ITU SS7 protocol. The address of a destination-signaling node is obtained by combining the global title and the called party address provided by the message originator. The Gateway Screening feature provides two levels of screening for network security, at the message transfer part (MTP), and signaling connection control part (SCCP) level. The feature is user-friendly, with simple Graphical User Interface (GUI) commands, and speedy download capability. The Application Transport Access feature redirects specific Ss7 message signaling units to a customized application. The feature intercepts messages that originate from the SS7 network and require further application processing, and redirects them to a specific application for further processing.

The MACH7fe Control Chassis provides a high-density, cost-effective solution to increase signaling capacity, support global connectivity, decrease space requirements, and reduce costs. The MACH7fe allows the platform to accommodate up to 144 E1 or T1 channels per fe control shelf. The High Speed Links interface modules provide greater bandwidth by using asynchronous transfer mode (ATM) technology.

SIGTRAN
SS7 over IP transport can provide significant savings for customers with long-haul links or geographically diverse needs and more bandwidth flexibility than traditional signaling links. The IP transport feature delivers high-capacity network solutions, providing a cost efficient, reliable, scalable approach for handling future signaling growth.
