ADM Last modified: Wednesday, September 05, 2001  Short for add/drop multiplexing, a multiplexing function used in SONET optical technology but can also be used in electric signal transmissions. ADM allows new signals to come in and existing signals to be dropped from a carrier channel by passing through an add/drop multiplexer. The goal of ADM is to add and drop signals without disrupting the onward transmission of other signals.   Related Categories Multiplexing Related Terms CDMA demultiplex EDFA FDM modulate multiplex multiplexer pulse code modulation SONET T-1 carrier T-3 carrier TDMA WCDMA WDM Shopping ADM Products Compare Products,Prices and Stores Shop by Category: Plumbing Supplies 222 Store Offers Office Supplies 35 Store Offers Building Supplies 105 Store Offers Vacuums 4 Store Offers Toys 19 Store Offers Search: WebMediaBrands Corporate Info Legal Notices, Licensing, Permissions, Privacy Policy.
