About East Coast Datacom, Inc

East Coast Datacom, Inc. is a customer oriented, high technology enterprise which was formed in 1994 to design, manufacture and support Wide Area Network Equipment. We manufacture the broadest line of Network Emulators in the network test equipment market supporting over 18 different interfaces for Serial, Telco and Ethernet.

For Ethernet, the WanRaptorâ„¢ Network Emulator allows users to test and stage critical network equipment adding network latency, loss, Jitter and re-ordering impairments. For Serial data and Telco the RDS-PLUS delay simulator is a modular, network link error and delay emulator that provides a realistic simulation of physical network behavior with respect to time delays and bit errors.

We also manufacture an extensive line of legacy network equipment critical to the military, government and Fortune 500 companies. These include data broadcast splitters, digital sharing devices, interface converters and many other network adapters. Our highly respected Sync2IP Converter is a unique solution for Sync data to IP conversion as we support any sync data protocol.

We hope you enjoy our collection of products we present on our web site. Keep in mind we can modify or design a new solution for your unique application.

East Coast Datacom (ECD), Inc., a Florida-based data communications accessory specialist, announces the RDS-SB Satellite Buffer with Differential Frequency Discriminator.

The RDS-SB is intended to provide a unidirectional 2.097 Mbit elastic data buffering (FIFO memory) function between two systems having nominally equivalent clocking rates. The two systems may be either running asynchronously, or may be traceable to a common timing source while one or both systems may possess a high degree of clock jitter. An option switch on the front panel allows the RDS-SB internal buffer memory to utilize a Differential Frequency Discriminator to prevent the FIFO memory from re-centering after an underrun or overflow until the frequency difference between the two external clocks is within a set range.

The 2.097 Mb First-In, First-out (FIFO) memory is used to buffer data inand out of the unit. Receive data may be simultaneously written into the FIFO while transmit data is read out. Internal counters track the FIFO level and are used to indicate underrun and overflow conditions, as well as indicate when the FIFO is half-full (centered) after initialization. A Differential Frequency Discriminator (DFD) may be invoked to conditionally hold off accepting received data and re-centering the FIFO after a power-on cycle, or an underrun or overflow condition occurs, until the frequency difference between the two port clocks falls within a set range of approximately 400 Hz. The purpose of this function is to prevent an out of range clocking source from repeatedly producing frequent underrun or overflow conditions.

When this function is invoked, and only after an underrun or overflow condition occurs, the FIFO memory is held in an initial state of emptyif the DFD indicates that the absolute frequency differential is outside the range. If at any time within the sample window of the DFD (approx. 20mS), this differential should fall within the range, the FIFO will re-center normally and begin transferring data. (NOTE: It is possible in some cases that the average frequency differential will be outside the range, but may at times fall within the range due to clock jitter. This will be sufficient to trigger re-centering of the FIFO and transfer of data.)

The RDS-SB has a list price of $1195.00 US Dollars.
