SC-SDT Applications Overview
The SpectraComm Synchronous Data Transfer device (SC-SDT) is designed primarily for
packetized, HDLC-based Synchronous Data Transport applications and Contact Sense
applications. The NEBS-compliant SC-SDT can be deployed anywhere in the IP network where
synchronous devices, craft port equipment or contact relays are located.
• DTE/DCE devices at any SC-SDT site can exchange sync data with devices at other SC-SDT
sites.
• From the Management Station, all SC-SDT units are managed via Telnet and HTTP.
Password-protected local (craft) access is also supported.
• The rear panel DB-25 connector provides contact ports for alarm traps. In a future release of the
device, alarm transfer between locations will be supported.
Figure 1-2 shows the SC-SDT at remote sites supporting multiple applications simultaneously.
Each application is detailed in the pages that follow the figure.
