CASE STUDY:

FTM Trunc Card

Project description

SS Telecoms required a redesign of the existing Trunc Card for their FctMux in order to provide a wider service offering as well as to resolve some obsolescence issues. Keystone Electronic Solutions designed a new card, FctThruMux Trunc Card (FTM TC), which is physically and functionally compatible with the existing trunc card but provides Ethernet and two E1 ports as connectivity options.

The Business Challenge

During the development of the FTM Trunc Card the need arose to combine technologies and working methods of SS Telecom and KSES in order to effectively tackle the task at hand. This strategy included an engineer from SS Telecom working full time at KSES to in order to fast-track the development process. KSES's proven management methodologies and detailed reporting standards provided for communication and coordination between all parties.

The KSES Solution

We at Keystone believe in incorporating the latest technology into our products. Consequently the ARM 9 series processor from Atmel was used for the control and routing in the card. A Linux operating system was implemented on the processor and various board-specific drivers developed. Other technologies incorporated into the FTM Trunc Card include a GSM modem, LAN controllers, an FPGA, SD memory, RS232 as well as USB connectivity.

How it Works

The FTM Trunc Card forms part of a larger GSM call routing system developed by SS Telecom. The function of the FTM Trunc Card specifically is to route the E1 channels to their proper destinations.

Future plans

The FTM Trunc Card will continue to be implemented in the telephony solutions from SS Telecom.
