2.2GENERAL PRODUCT DESCRIPTION

The Model 2500RC Series CSU/DSUs operate either synchronously or asynchronously over 4-wire circuits up to 64 Kbps. Rate conversion allows operation with a variety of DTE devices. Diagnostics include V.54 and V.52 loopback tests, as well as CSU loops. Configuration is accomplished by either internal DIP switches or RS-232 software switches (user provides terminal). Nine easy-to-read function card LED indicators monitor data and control signals. Two rear interface cards are available: DB-25 and RJ-48 or M/34 and RJ-48.

The Model 2500RC Series is AT&T compliant and supports DDS, Switched 56, Clear Channel 64 and other digital services available from major service providers including AT&T, Sprint and MCI. Dedicated models can also be used as a high speed modem for private twisted pair. The Model 2500RC Series is available in standalone or in rack- card versions (only rack card versions are covered in this manual).

2.3 SUPPORTED APPLICATIONS

The Model 2500RC Series includes three units: the Model 2500RC All-Rate CSU/DSU, the Model 2510RC Switched 56 CSU/DSU and the Model 2520RC All-Rate/Switched 56 CSU/DSU. Depending upon the unit selected, the Mode 2500RC Series supports three distinct modes of 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 Channel operation 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 match the rate of service to which you subscribe. Set the Mode switches for Network Clocking. The Rate Converter and the Data Format options should be set as required for your application. The remaining options may need to be set depending on your terminal equipment and your application.

Switched-56 Operation (Models 2510RC, 2520RC)

The unit can be used in Switched 56 applications. Set the Line Rate to 56 Kbps. Set the Mode switches for Switched 56, and enable Force RTS and Circuit Assurance. Dial or store a number using the control port. The Rate Converter and the Data Format options should be set as required for your application. The remaining options may need to be set depending on your terminal equipment and your application.

Campus Area Short Haul Operation (Models 2500RC, 2520RC)

The unit can also be used for campus area point-to-point short-haul applications on private twisted-pair wires. Set the Line Rates the same on both units. Set the Mode switch for the appropriate Transmit Clock Mode for your application. Internal, External and Looped Clock Modes are available. Set the remaining options as needed by your terminal equipment or your application.
