Alcatel-Lucent 3AL34787AA-series Enhanced Clock Recovery Unit (0.37 ppm) timing card for 1651SM/1661SMC and 1660SM-family SDH ADM shelves.

The 3AL34787AA-series is an Enhanced Clock Recovery Unit (CRU) card, specified to 0.37 ppm stability, for the Alcatel-Lucent SDH add-drop multiplexer family (1651SM/1661SMC and related 1660SM-series shelves). The CRU generates and distributes the shelf’s internal timing reference, recovering synchronisation from a chosen network timing source and locking the multiplexer’s SDH frame clock to it so that all tributary and aggregate cards in the subrack stay frequency-aligned; the “Enhanced” 0.37 ppm variant offers tighter long-term frequency stability than the standard clock module, reducing pointer-justification events on high-capacity rings. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare/replacement timing card for engineers maintaining Alcatel-Lucent SDH transmission networks; get in touch to confirm current stock and compatibility with your shelf release.
