1.2 ARC-101 Features

This section provides a brief description of the ARC-101's main features.

The ARC-101 supports a wide variety of ATM data rates and media types, both electrical and optical.

The electrical interfaces supported are:

∙2 Mbps E1 over Coax/UTP

∙34 Mbps E3 over Coax

∙45 Mbps T3 over Coax

∙155 Mbps STS-3c/STM-1 over Coax

∙155 Mbps STS-3c/STM-1 over Cat-5 UTP

The optical interfaces supported are: Multimode, Single Mode LEDs and LASERs and 155 Mbps STM-1/STS-3c.

Multiple connector types are available for both electrical and optical interfaces.

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 Available Bit Rate (ABR) traffic management specifications, in order to avoid FIFO overflow.

The modular software-based design of the ARC-101 enables easy migration to new ATM physical interfaces.

Built-in diagnostics, configuration and statistics are provided via an ASCII terminal connected to the RS-232 CONTROL port.

LED indicators provide information on ARC-101 general status (power and self-test), as well as left and right link status (ATM activity and link synchronization).

The ARC-101 complies with ATM Forum specifications.
