Digital ATM 4-Port Modular Line Card Daggl-BC

This document provides critical information for the installation, use, and maintenance of the DIGITAL ATM 4-Port Modular Line Card (DAGGL-BC). This line card functions as a logic module, supporting various ATM modular PHY (modPHY) cards for different connection types (e.g., STS-3c, T3, E3, E1, T1) and performing ATM cell-forwarding across its four ports.

Key sections detail the minimum required firmware (V2.7) and CMM (V1.92) versions, noting that expanded memory may be necessary for certain firmware releases. The document outlines procedures for installing and removing the line card, expanded memory options (SODIMM), and DC-to-DC power modules. A significant portion is dedicated to testing the line card, explaining the meaning of its Module and Link LED indicators during module self-test, firmware loading, and normal operational status, including diagnostic codes for troubleshooting. It concludes by referencing other documentation and online resources for safety, product specifications, and regulatory information.
