Interface Cards (LICs) or Network Interface Controllers (NICs).
Application 1 utilizes the IWE8 as an internetworking device for communication between
a narrowband Time-Slot based network and an ATM network.
Application 2 utilizes the IWE8 chip to enable the use of an existing T1/E1 access line
for connection to an ATM network.
In application 3, the IWE8 chip enables terminals using a Leased Line or Time-Slot
based service to convert from T1/E1 network connection to ATM network connection
without noticeable changes to the subscriber.
Figure 2
The PXB 4220 IWE8 chip is designed to handle up to eight T1/E1 ports. It transfers data
between the Pulse Code Modulation (PCM)-highway and an UTOPIA ATM Interface.
