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.

2.2 GENERAL 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).
