A Transport Mode Application
The asynchronous transport mode of the SC-ADT links async equipment together over the
customer's IP network. The SC-ADT encapsulates the async traffic into IP packets and forwards the
data over Ethernet to the local router/bridge (or to companion product, the SCIP router) for transfer
over the IP network. The async data at any local SC-ADT port can be forwarded to any async port
at any remote SC-ADT location.
Each SC-ADT front panel connector allows connection with up to eight local asynchronous
customer equipment ports. For higher density requirements, simply add more SC-ADT devices to
the ethernet segment at each site. Individual async data ports are configurable for Baud, Data/Start/
Stop Bits and Parity. External adapters allow connections to either terminal (DTE) or modem
(DCE) devices.
shows multiple sites with async equipment linked together over the customer's IP
Network. Any DTE at any SC-ADT site can exchange async traffic with any other DTE.
Note
The SC-ADT device is required at both ends of a link to support the proprietary encapsulation scheme.
