Description:
The NTEU86AA is an internal functional card used in Nortel external multiplexer systems — telecom equipment that aggregates and maps lower-rate digital streams (such as PDH) into higher-order signals for transport. Specifically, this card is described as a 1:N 2 Mb/s Mapper Card, meaning it supports mapping of 2 Mb/s tributary channels in configurations where one main channel (or mux) is shared across multiple client streams.
