2.3 Asynchronous Transfer Mode (ATM) Service Modules (ASM)
The Remote Terminal provides the interface to network services at the customer premise. The Remote
IDU has four (4) UTP-5 ATM Interface Ports and can be connected to ASMs that can provide the following
interfaces for customer interconnect:
• T1 Circuit Emulation Services (CES)
• E1 Circuit Emulation Services (CES)
• T1 Frame Relay
• E1 Frame Relay
• Ethernet 10BaseT
These ASMs provides the ATM conversion necessary to provide connectivity for a broad range of user
equipment and operates with no service affecting interdependicies. Figure 2-3 illustrates the ASMs avail-
able.
