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.

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.
The ARC-101 supports a wide variety of ATM data rates and media types,
both electrical and optical.
Interfaces
Supported
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.
Rate Adaptation
Easy Migration
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.
User
Management
and Monitoring
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).
Indicators
The ARC-101 complies with ATM Forum specifications.

ARC-101 Installation & Operation Manual
Chapter 1. Introduction
ATM cells are transferred from one interface to the other through an
internal bus, the bandwidth of which is 180 Mbps.
Traffic
Management
• 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.

ARC-101 Installation & Operation Manual
3.1 Operating Procedure
The interface modules are not hot-swappable. If you install or change
modules, make sure to first disconnect power to the ARC-101, and then
remove/install modules slowly and carefully (so as not to damage the modules
or the ARC-101 enclosure). See section 2.6.
Note
Install the ARC-101 as described in Chapter 2. Make sure that the power
cord is connected to the ARC-101's power connector on the rear panel.
Plug the other end of the power cord into the mains outlet. The PWR
indicator on the front panel should light.
Turning on the
ARC-101
Upon power-up, the ARC-101 goes through a self-test that takes about
40 seconds to complete. The FLT indicator is ON during the self-test. After
the self-test is completed, if no faults have been detected, the FLT indicator
is OFF. Detailed test results can e viewed from an ASCII terminal
connected to the ARC-101's CONTROL port.
The ARC-101 operates unattended. During normal operation, the PWR
indicators should light continuously, the FLT indicator should be OFF, the
ATM indicator should light up when ATM traffic passes through the
module, and the SYNC indicator should light up continuously.
Normal
Operation
To turn off the ARC-101, disconnect the power cord from the mains outlet.
Turning off the
ARC-101
The following table lists several common problems and their possible
solutions.
Procedure in
Case of
Malfunctioning
The PWR LED does not light up
Fault (FLT) LED blinks
−
Check the power cord connection on the back of the unit and at the
mains outlet.
−
−
Verify power availability at the mains outlet.
Unplug the unit (power OFF). Make sure that the modules are inserted
properly. Tighten the modules' screws. Power ON the unit.
−
Using an ASCII terminal port, check for a fault indication in the
Diagnostics window. If there is a fault, inform a qualified ARC-101
technician.
−
Ensure that the plugged-in modules are compatible with the protocol
used (media, data rate).
Data transmission difficulties
−
−
Check the module's software configuration in the Configuration window.
Verify that the SYNC indicator is ON. If it is OFF (indicating a fault in the
data reception link), run diagnostics on the remote unit from which data
is being transmitted to the ARC-101. If it is BLINKING (indicating a fault
in the data transmission link), run diagnostics on the remote unit, or
implement a loop on the ARC-101 module, and verify that the
SYNC LED is ON.
