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.
