Description of the RAD ARC-101
| ARC-101, ATM rate and media converter, provides transparent rate and
media conversion between two ATM interfaces by extracting ATM cells from
one interface and sending them over the second one. |
| RAD ARC-101 connects devices with dissimilar ATM interfaces.
Alternatively, ARC-101 can be used in ATM testing environments, enabling
module interchangeability according to the devices being tested. |
| A large internal FIFO is used for rate adaptation between the two
interfaces and for handling the bursty nature of the ATM traffic.
Special circuitry is responsible for closing the ATM flow control loop
according to ABR traffic management specifications in order to avoid
FIFO overflow |
| ARC-101 supports a wide variety of ATM data rates and media types.
These include:
E1, E3, T3 and STS-3c/STM-1 over optical and electrical interfaces. |
| The modular construction of the RAD ARC-101 and software based design
of RAD ARC-101 enables easy migration to new ATM physical interfaces. |
| Built-in diagnostics, configuration, statistics (including physical
layer alarm surveillance/ performance monitoring) and ATM layer
statistics are provided via the monitor connector (RS-232 ASCII
terminal). |
| The RAD ARC-101 is supplied as a standalone unit. Special hardware for
mounting one or two units in a 19" rack using minimal height of 1U
can be ordered separately (see Ordering). |
