SPD-64 -- 56 to 64 Kbps Rate Adaptor

Rad Data Communications Inc.

SPD-64 is a synchronous TDM multiplexor that acts as a rate adaptor. Itconnects 56 or 48 Kbps terminal equipment to a 64 or 56 Kbps datacommunication line. It provides a low-data-rate (4.8 or 9.6 Kbps)synchronous subchannel that can be used for connecting additional localor remote terminal equipment over the same link.Main channel transmit and receive clocks are external, provided by the 64Kbps communication link. Subchannel clocks can be driven from the mainchannel transmit clock or externally, from the data communicationequipment.Internal elastic buffering provided on the subchannels compensates forminor clock differences between the main channel and the subchannels. Afield- selectable main channel interfaces with either X.21 or V.35.Front panel LED indicators enable continuous monitoring of the mainchannel activity and synchronization.SPD-64 tabletop unit connections are made through rear panel connectors.Minimal strapping adjustments enable easy installation and operation.
