Alcatel-Lucent 3AL78831AA A21E1 21x2Mbit/s (E1) tributary access module, 75-ohm for the 1660SM and 1662SM-C SDH platform.

The ALCATEL 3AL78831AA is a A21E1 21x2Mbit/s (E1) tributary access module, 75-ohm for the Alcatel-Lucent 1660SM and 1662SM-C synchronous digital hierarchy (SDH) multiservice provisioning shelves. it provides 21 ports of 2Mbit/s (E1) tributary access at 75-ohm impedance on a single plug-in card, letting the shelf terminate a large number of low-speed E1 tributaries from one slot. It is a like-for-like spare for engineers maintaining legacy Alcatel-Lucent SDH transmission networks. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare/replacement A21E1 access module; get in touch to confirm current stock and shelf-release compatibility. This module is a common maintenance spare for operators running dense E1 tributary aggregation on 1660SM and 1662SM-C shelves, where sourcing OEM A21E1 cards through the manufacturer’s own channel is no longer practical.
