IDM MAP4E1-30 Integrated Service Cross-Connect Multiplexer

Overview

The IDM MAP4E1-30 Integrated Service Cross-Connect Multiplexer is a comprehensive service platform integrating 64K narrowband service access, PCM multiplexing, and 64K timeslot cross-connection.

The IDM MAP4E1-30 is primarily used for service access and cross-connection at the access layer of data communication networks. It features complete synchronization and timing functions, providing non-blocking 64K-level cross-connection across 4 E1 channels, while supporting up to 30 channels of 64K services, including telephone, magneto telephone, common battery telephone, and V.24 data services.
