Standard Context Routing (SCR)
SCR allows the central host to communicate with hundreds, even
thousands of terminals across a single host connection. But the real
advantage of using SCR is economic: The host only pays for a single
connection to the network, significantly reducing communications cost.
When a terminal sends a message to the host, the message must contain
a header that includes the sending terminal ID. This enables the host to
identify which terminal sent the message and which terminal the host is
to poll.
DataTAC System Architectures
Other header fields provide the host with options for instructing the
network on handling undeliverable messages. For example, the host
can ask the network to:
Provide a delivery status of messages.
Hold messages on the network for a later delivery.
Discard messages.
This header and instruction information is the basis of the SCR
protocol.
