Chapter 1 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.
ARC-101 Installation & Operation Manual Chapter 1. Introduction 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.
ARC-101 Installation & Operation Manual Traffic Management Chapter 1. Introduction 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.
ARC-101 Installation & Operation Manual Chapter 1. Introduction 1.3 Specifications Up to 155 Mbps Data Rate Indicators Control Port PWR ON when unit is powered FLT BLINKS when self-test fails (ON during self-test) ATM ON when ATM cells were transmitted and received in the last second and no uncorrected HEC errors were detected. SYNC ON when the port is synchronized (no alarm) OFF during local alarm BLINKS during remote alarm reception Interface RS-232/V.

Chapter 2 Installation This chapter contains mechanical and electrical installation procedures for connecting the ARC-101 to the main power supply, as well as cabling the ATM links and monitor (control) port. 2.1 General The ARC-101 is delivered completely assembled for bench-top installation. The ARC-101 may be optionally installed in a 19" rack (refer to Section 2.4). 2.2 Unpacking • • • • Site Requirements Inspect the equipment container before unpacking.
ARC-101 Installation & Operation Manual Chapter 2. Installation 2.3 Site Requirements Power The ARC-101 is powered by 90/260 VAC or -48 VDC. The unit should be installed within 1.5 meters (5 ft.) of an easily accessible grounded AC outlet capable of supplying the appropriate voltage (90/260 VAC). Front and Rear Panel Clearance Allow at least 90 cm (36 inches) of clearance at the front of the unit for operator access.
ARC-101 Installation & Operation Manual Installation of Two Units Chapter 2. Installation Rack adapter components for installing two units include two short side brackets (for rack mounting) and two flat rails (for fastening the two units together) Figure 2-2 Installation of Two Units To install two units follow these instructions: 1. Place two units side by side. On the top of each unit are four grooves. The grooves should line up when the units are placed side by side. 2.
ARC-101 Installation & Operation Manual Chapter 2. Installation When the ARC-101 is used as a DCE or as a DTE, the RJ-45 pinout is: Pinout DCE DTE Pin 1 Pin 2 Pin 3 DTR Pin 4 GND GND Pin 5 TX Data RX Data Pin 6 RX Data TX Data Pin 7 CTS Pin 8 Pin 9 Changing Control Port Mode RTS The ARC-101 is shipped as a DCE. To connect the ARC-101 to a MODEM, the control port mode must be configured to DTE. To change the control port mode from DCE to DTE, or vice versa: 1.
ARC-101 Installation & Operation Manual AC Power Connection Chapter 2. Installation The ARC-101's power connector is located on its rear panel (see Figures 2-6 and Figure 2-7). AC power should be supplied to the ARC-101 through a 1.5 m (5 ft.) standard power cord terminated by a grounded 3-wire plug. Warning When applying AC power, first connect the plug of the AC cable to the power connector on the rear panel of the ARC-101 and then to the mains outlet.

Removing Modules ARC-101 Modules Turn the unit OFF (disconnect the power cord). Pull on the screws on the module's front panel, so they hang outwards a little. Insert the module onto the sliders, and push the module slowly into the unit (make sure that the module is correctly aligned on the sliders).
ARC-101 Installation & Operation Manual Chapter 2. Installation Jumper Settings for E1 and E1/LTU The jumpers JP5, JP6, JP10, JP11 and JP13 are used to select the link interface (Coax or UTP). See Figure 2-16. Figure 2-16 E1 and E1/LTU Jumper Locations Note Turn the module upside down in order to see and move the jumpers. • JP5, JP6: Designated BAL/UNBAL. BAL (up) for operation in Balanced mode (UTP). UNBAL (down) for operation in Unbalanced mode (Coax, default).
