Introduction

1.1 General Description

The ARC-101, ATM Rate & Media Converter, provides transparent ATM rate and media conversion between two interfaces by extracting ATM cells from one interface at one rate and sending them over a different interface at a different rate.

The 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 ARC-101 is supplied as a standalone unit. Special hardware for mounting the unit in a 19" rack can be ordered separately.

A typical ARC-101 rate conversion application is shown in Figure 1-1.

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

User

Management

and Monitoring

Indicators

Compatibility

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.

ARC-101 Installation & Operation Manual

Chapter 1. Introduction

 

 

Traffic

Management

Loopback Mode

ATM cells are transferred from one interface to the other through an internal bus, the bandwidth of which is 180 Mbps.

Cells that are received with a multiple-bit HEC error are dropped.

Cells received at the slower interface are transferred directly to the other interface.

Cells received at the faster interface are transferred through the FIFO which absorbs temporary bursts of ATM cells and transfers them according to the other interface data rate.

The FIFO depth is 6K cells in SONET/SDH interfaces and 3K cells in other interfaces.

The ARC-101 implements a single priority queue FIFO. Special circuitry is responsible for the traffic management and for avoiding FIFO overflow.

The total bandwidth of CBR cells cannot exceed the slow interface bandwidth.

The total bandwidth of VBR cells can only temporarily exceed the slow interface data rate. If this bandwidth is exceeded, cells are queued in FIFO and are transferred according to the slow interface data rate.

The ARC-101 has a configurable congestion threshold (limit) used to handle UBR/ABR traffic. You can configure the threshold to be 25%, 50%, 75%, 90% or 100% of the total FIFO depth.

In order to control the UBR/ABR traffic bandwidth, you can configure the ARC-101 for EFCI marking of cells that are received while the FIFO is congested, or configure AAL5 Early Packet Discard mode in which a whole frame is dropped in case of congestion, except for the last cell.

You can configure the ARC-101 to discard cells whose CLP bit is set, when FIFO is congested.

The number of cells from a certain VP/VC is limited to 3/4 of the total queue depth, in order to minimize the effects of large bursts of data from one VC on the other VCs in the ARC-101.

The ARC-101 recalculates the HEC field of cells whose EFCI bit was changed.

Each ARC-101 interface can be separately configured for Remote or Internal Loopback mode. The Remote Loopback mode enables a loopback of the incoming data and clock to the transmit data and clock outputs. The Internal Loopback mode enables a loopback of the transmitted data to the received data. Remote Loopback is not available in the E1 interface.
