2.3 SUPPORTED APPLICATIONSThe Model 2500RC Series includes three units: the Model 2500RCAll-Rate CSU/DSU, the Model 2510RC Switched 56 CSU/DSU and theModel 2520RC All-Rate/Switched 56 CSU/DSU. Depending upon theunit selected, the Mode 2500RC Series supports three distinct modesof operation. These are outlined in the descriptions and table below:Dedicated DDS/Clear Channel Operation (Models 2500RC, 2520RC)The unit can be easily configured for dedicated DDS/Clear Channeloperation by means of the dip switches on the bottom of the enclosure,or by means of the software control port. Set the Line Rate to matchthe rate of service to which you subscribe. Set the Mode switches forNetwork Clocking. The Rate Converter and the Data Format optionsshould be set as required for your application. The remaining optionsmay need to be set depending on your terminal equipment and yourapplication.Switched-56 Operation (Models 2510RC, 2520RC)The unit can be used in Switched 56 applications. Set the LineRate to 56 Kbps. Set the Mode switches for Switched 56, and enableForce RTS and Circuit Assurance. Dial or store a number using thecontrol port. The Rate Converter and the Data Format options shouldbe set as required for your application. The remaining options mayneed to be set depending on your terminal equipment and yourapplication.Campus Area Short Haul Operation (Models 2500RC, 2520RC)The unit can also be used for campus area point-to-point short-haulapplications on private twisted-pair wires. Set the Line Rates the sameon both units. Set the Mode switch for the appropriate Transmit ClockMode for your application. Internal, External and Looped Clock Modesare available. Set the remaining options as needed by your terminalequipment or your application.62.0 GENERAL INFORMATIONThank you for your purchase of this Patton Electronics product.This product has been thoroughly inspected and tested and iswarranted for One Year parts and labor.
