Central Office Multiplexing (or CO Muxing) is Central Office equipment that derives a number of lower speed channels from one high-bandwidth channel. Central Office multiplexing is needed when the customer wants to terminate the DS1 or DS3 in the Central Office and wants to ‘pick up’ lower level services. For example, a customer may order a DS3, using it to carry a number of DS1 level services from different IXC carriers.
