Application

The AT3-6ME Interface Adapter is used with the BPX Broadband ATM Switch in applications where it
is required to interface a 6 Mbps T2 digital network facility to the 45 Mbps T3 ATM port on the BPX or
IGX node.
Applications include networks where T2 transmission facilities are available. Users with ATM networks
who require somewhat more bandwidth than is provided by the T1 or E1 ATM network connections but
do not need the full T3 bandwidth provided by the BPX ATM network ports can also benefit from using
the AT3-6ME Interface Adapter. For a typical application, see Figure 32-1.
