## Long description

ISDN Mixed Module ALCATEL 3EH77238AD – 2 T0 lines, 4 UAI ports is a modular interface card designed to add ISDN connectivity to compatible Alcatel enterprise telecom systems. The module provides two T0 (2.048 Mbps) trunk interfaces alongside four UAI user access ports, enabling mixed configurations of trunk and user connections for voice and signaling over ISDN. The unit is intended for insertion into supported chassis or slots in Alcatel switching equipment and facilitates integration with PSTN/ISDN services and internal telephony platforms.
Advantages

With two T0 lines and four UAI ports it supports flexible deployment scenarios, allowing administrators to assign trunk capacity and user lines according to site requirements. The design follows Alcatel hardware compatibility guidelines to ensure predictable interoperability and to maintain signal integrity for voice and signaling channels.
Suitable for
Enterprise PBX expansions requiring mixed ISDN trunk and user ports
Sites needing multiple ISDN interfaces for PSTN/ISDN connectivity
Telecom installations where modular scalability and slot-based upgrades are used
Replacement or upgrade of existing compatible interface modules
