U-Interface Line Card (UILC)
Nortel NT6D71AC U-Interface Line Card – UILC Digital Trunk Module for Meridian Systems – 2B+D ISDN PRI Compatible
Nortel NT6D71AC UILC Line Card – 12-port ISDN U-interface card for Meridian PBX systems with 2B+D trunking.
Product Description:
The Nortel NT6D71AC U-Interface Line Card (UILC) is a digital trunk module engineered for use with Meridian PBX systems. This interface card is designed to support Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) lines using a 2B+D configuration, making it ideal for delivering digital voice and signaling over a single twisted-pair line. Commonly deployed in enterprise-level telecommunication infrastructures, the NT6D71AC provides reliable and cost-effective connectivity between a Meridian switch and terminal equipment or remote modules.
Built to handle up to 12 U-Interface ports per card, this module delivers point-to-point and point-to-multipoint communication with excellent signal integrity and network compatibility. The NT6D71AC is designed to support long-distance transmission using a two-wire interface, often exceeding distances achievable with traditional S-Interface modules, which makes it especially useful for large-scale campus or remote-building applications.
Designed with reliability in mind, this UILC card minimizes signal degradation and supports key ISDN features such as D-channel signaling, call control, and high-speed data transmission. As part of the Meridian platform, the NT6D71AC offers seamless integration and is field-proven for use in high-demand environments including financial institutions, government offices, and enterprise networks.
