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.
Configurable connectivity
AC203x family offer flexible ShDSL Network Termination
Points with different operating modes:
• ATM Circuit Emulation Service (CES)
• Frame Relay to ATM Interworking
• Cell Bridging to transport ATM cells between the ShDSL
network interface and the E1 service interface
• Time-Division Multiplexing (TDM)
High-performance digital subscriber line access multiplexer
(dslam) transmission
AC203x, connected to a DSLAM, terminates the ShDSL and
many other xDSL links. AC203x cross connects and
concentrates up to 128 Virtual Circuit Connections (VCC) over
a single or a dual high speed link to the backbone ATM
network, reaching up to 4608kbps (4-wire mode). Deploying
an inexpensive and highly scalable network infrastructure
using AC203x replaces obsolete DCE, HDSL transceivers, TDM
cross-connects, and other leased line network equipment.
