FORE Systems NM-4/155MMSCE: 4-port OC-3 ATM interface module, multimode fibre, ‘Series E’ revision of the NM-4/155MMSC family.

The FORE Systems NM-4/155MMSCE is a 4-port OC-3 multimode-fibre ATM network interface module for FORE’s ATM switching platforms, the ‘E’ (Series E) revision of the NM-4/155MMSC family alongside the ‘C’ and ‘D’ revisions sold under the same base part number. Modules in this family populate a switch’s line-card slots to add OC-3 ATM trunk or edge capacity over multimode fibre; later revision letters typically indicate a hardware or firmware refresh rather than a change in function or port count. FORE Systems built some of the earliest commercial ATM switches before its 1999 acquisition by GEC (reformed as Marconi) and Marconi’s later 2006 transmission-asset sale to Ericsson. Genuine units are a routine requirement for maintaining or expanding an existing legacy ATM installation.
