AC203x is a family of highly
flexible Network Termination
Units that connect directly
a DTE with Serial and/or E1
interface to an ATM network
through a ShDSL line.
AC2036 and AC2037 models,
respectively 2-wire and 4-wire,
provide two different operating
modes, E1 Cell Bridging
and Frame Relay to ATM
interworking functionalities.
