Traffic aggregation with the DS3-ATM module

The ports of the DS3-ATM trunk module can be used to aggregate the traffic of
several Stinger MRT units. DS3 traffic passes into and out from the ATM switch
through only one unit. Figure 11-3 shows this type of connection.

DS3-ATM traffic aggregation connection

For DS3-ATM traffic aggregation, the units must be connected as follows (see
Figure 11-3):
The receive connector of port 1 on the DS3-ATM trunk module in the top unit is
connected directly to the transmit connector of port 2 on the module in the
second (bottom) unit.
The transmit connector of port 2 on DS3-ATM module in the second (bottom)
unit is connected directly to the receive connector of port 1 on the module in the
top unit.
