Chapter 1. Introduction ARC-101 Installation & Operation Manual

1-2 ARC-101 Features

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

Interfaces

Supported

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.

Rate Adaptation 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.

Easy Migration The modular software-based design of the ARC-101 enables easy migration

to new ATM physical interfaces.

User

Management

and Monitoring

Built-in diagnostics, configuration and statistics are provided via an ASCII

terminal connected to the RS-232 CONTROL port.

Indicators 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).

Compatibility The ARC-101 complies with ATM Forum specifications.
