DS-3 MDA: 8672ATME and 8672ATMM modules

Each MDA has ports for connection to an ATM network. OC-3c/STM-1 and

OC-12c/STM-4 MDAs support concatenated transmission.

The flexibility of connectivity is achieved by mixing different types of MDAs.

The following table shows the available types of MDAs for the 8672ATME

and 8672ATMM modules.
