ALCATEL 3FE27289BB -Lucent ISAM FD / 7330 ISAM FTTN access platform Telecom System Card / Module

The Alcatel 3FE27289BB is a 48-line outdoor ISDN line card, designated NALT-D, for the Alcatel ISAM FD (Fibre Distribution) remote node family used across the 7330 ISAM FTTN and related access platforms. It is the ISDN-capable sibling of the NALT-C POTS-oriented outdoor line card (3FE27289AB), provisioning 48 ISDN-capable subscriber lines from an FD remote cabinet or pedestal sited outside the exchange, close to subscribers. This supports fibre-to-the-node/cabinet deployments that need to retain ISDN service alongside broadband on the same remote node, rather than POTS-only lines. ISAM FD shares core technology with the wider ISAM family, including the 7302 ISAM and 7330 ISAM FTTN, used to deliver broadband and IPTV services over existing copper plant. Tech-Star (UK-based, shipped worldwide) supplies tested ISAM FD line cards; contact our engineers to confirm compatibility with your specific remote node configuration before ordering.
