Open-access system for CompactPCI H.110 computer telephony applications eliminates extender boards and speeds development
Tracewell Systems (Westerville, OH) announces its new T-Frame for CompactPCI H.110. This new development system for computer telephony applications integrates a time division multiplexing (TDM) bus along with the CompactPCI bus to support real-time voice or signal data. By combining these features with Tracewell's patented open-frame design, a telephony system developer has direct access to installed cPCI boards without the use of performance degrading extender cards, which are required when a standard H.110 chassis is used.
By using the Tracewell T-frame, a developer also has test access to the component side of installed boards because of the chassis' left justified system slot. Moreover, this unique system provides the most comprehensive monitoring functions available. By solving challenging measurement, control and board accessibility problems during development, T-Frame reduces design cycles and time to market.
Tracewell's T-Frame is a complete implementation of the telephony-oriented features of H.110 and the mechanical advantages of CompactPCI, including hot-swap features. So it accepts a wide range of low-cost, off-the-shelf plug-and-play products and supports related application software developed for desktop PCs. This makes the T-Frame an ideal system development package for computer telephony applications.
The T-Frame includes comprehensive monitoring of all backplane voltages, current and /exhaust air temperature and displays this information on the front panel. In addition, a convenient front interface provides fan speed and voltage control, including +5 and +3.3 volt margining. Single or dual 350W plug-in power supplies are available, allowing hot swap power simulation, N+1, or 700W operation. Power supplies may be installed in either the front or rear cardcage, further improving accessibility. Cooling fans are adjustable to full or half speed and automatically turn-off when not in use to reduce noise. The 8-slot, 64-bit backplane is hot-swap compatible and supports standard 3U or 6U board sizes.
The T-Frames' IEEE 1101.10/11 compliant cardcage is constructed of rigid steel using a high-strength design that eliminates the flex common in conventional extruded rail construction. The result is a rugged yet easily portable product that stands up to the rigors of today's telecom, industrial and military applications. This rear I/O cardcage is adjustable for a wide range of board depths. To make the developers job even easier, the T-Frame has a tilt base, removable side access covers, recessed carrying handles, and internal 3.5-in peripheral bay.
