Section 1, System Description ATLAS 550 System Manual

1. SYSTEM OVERVIEW

The ATLAS 550 is a modular, highly scalable platform that provides robust solutions for the wide-area communication needs of small-to-medium corporations and network access providers. The ATLAS 550 is an Integrated Access System with extensive support of dedicated bandwidth management and access switching. It contains a high-performance CPU and powerful communications drivers which support applications such as frame relay, dial-backup, and PPP (point-to-point protocol).

The ATLAS 550 architecture also includes a packet and circuit switching bussing scheme. The result is a system capable of supporting bandwidth requirements of up to 9 T1 circuits or 5 Primary Rate ISDN (PRI) circuits. Designed for standalone, rackmount, or wallmount installations, the ATLAS 550 base unit provides two hot-swappable network interfaces and four expansion slots that accommodate hot-swappable option modules for a variety of applications. A 10/100BaseT Ethernet connection for IP routing and network management is standard with the ATLAS 550 base unit.

With the ATLAS 550, you can consolidate your voice, data, and video applications into a single platform while optimizing wide area bandwidth and reducing equipment costs. The ATLAS 550 architecture and the four expansion slots allow for a variety of modules, making it one of the most versatile access systems on the market.

Each option module has a variety of performance and alarm status information. Several features of each module are user-configurable, although default values reflect the most common configurations. All option modules contain an extensive self-test as well as tests designed for the technology they incorporate.

4. REVIEWING THE REAR PANEL DESIGN

AC System

The ATLAS 550 (AC System) rear panel contains four slots for housing option modules which provide a variety of additional resources and data ports. All slots are functionally identical. The ATLAS 550 also contains two slots for housing network modules (see Figure 2).

CONTROL IN Port

The CONTROL IN port (RJ-45) connects to a computer or modem or to another ATLAS 550 unit. The

CONTROL port input provides the following functions:

• Accepts EIA-232 input from a PC or a modem (for controlling the ATLAS 550)

• Operates at 2400, 9600, 19200, or 38400 bps

• Acts as input for either VT100 terminal or PC (with terminal emulation software) control

• Acts as an interface for flash memory software downloads and configuration transfers using XMODEM

The

CONTROL IN connection follows, and Table 4 shows the pinout.

8 CTS Clear to send - flow control

CONTROL OUT Port

The CONTROL OUT port (RJ-48C) connects to other ADTRAN products’ CHAIN IN connectors. The

CONTROL port output provides the following:

• EIA-232 output to chain control to other ADTRAN equipment, such as a TSU 120 or another ATLAS

• 2400, 9600, 19200, or 38400 bps operation

• Automatic setup; no user input required

CONTROL OUT connection follows, and Table 5 shows the pinout.
