A wideband data station which can transmit binary serial data over half-group, group, and supergroup bandwidth telephone facilities at speeds up to 19.2, 50.0 and 230.4 kb/s, respectively, is described. A modular design permits many optional service features and operating arrangements to coordinate with a variety of customer terminal equipment arrangements and a variety of line facilities. An option is available for transmitting low-speed coordination data over an associated voiceband channel which is always provided. Remote test features are provided for ease of maintenance. The high-speed data channel of the station may be operated synchronously or nonsynchronously. In synchronous service, the station provides a transmit clock, receive recovered clock, signal regeneration and a self-synchronizing scrambling arrangement for spreading the signal energy over the available bandwidth of the high-speed channel. A restorer at the receiver reinserts the dc and low-frequency components of the signal removed at the transmitter for transmission reasons. A vestigial sideband modem is provided in half-group service.
