Introduction & Specifications
SC-ADT Applications Overview
The SpectraComm Asynchronous Data Transfer device (SC-ADT) is designed primarily for
Terminal Server and Asynchronous Data Transport over IP applications. NEBS-compliant SC-
ADT can be deployed anywhere in the network where asynchronous devices, craft port equipment,
dry contact devices or contact relay devices are located.
•
From the Management Station, all SC-ADT units are managed via Telnet, SNMP, and HTTP.
Password-protected local and dial-in access is also supported.
•
At SC-ADT sites, some async ports can be configured as terminal server ports, some to
exchange async data with other sites, some for external modem connections, some as contact
sense inputs.
•
The rear panel DB-25 interface provides contact input connections to external devices. SC-
ADT detects state changes and can be configured to send contact alarm traps to an SNMP
controller. This interface also provides output connections for opening or closing a circuit that
applies a specific operational state at the external device.

shows the SC-ADT at remote sites supporting multiple applications simultaneously.
Each application is detailed in the pages that follow the figure.
