2.3 SUPPORTED APPLICATIONS
The Model 2710A provides a T1 (DS1) network termination
between the service provider and customer premises equipment (CPE)
such as a router. The Model 2715 can be used as an E1/FE1 to V.35
Converter, an T1/FT1 Network Terminating Unit, and also as a high-
speed short haul modem for campus applications.
2.3.1 The 2710A as the Interface between the Telco and CPE
The Model 2710A provides the interface between the service
provider and customer equipment, such as a router or switch (See
below).
2.3.2 The 2710A as a High-Speed Short Range Modem
The Model 2710A can also be installed into high-speed campus
applications. In this application, a pair of Model 2710A units operate
as short range modems (see below).
3.0 CONFIGURATION
Before placing the Model 2710A into service, the unit must be con-
figured to match both the DTE and Network interface parameters.
Configuration may be accomplished using pc board mounted DIP
Switches or via software using the RS-232 control port.
3.1 DIP SWITCH CONFIGURATION
The Model 2710A has sixteen internal DIP switches that allow con-
figuration for a wide range of applications. The sixteen switches are
accessed by opening the plastic case with a small screwdriver. Figure
1 (below) shows the location of the DIP switches on the bottom of the
printed circuit board.
The Model 2710A DIP switches can be configured as either “On” or
“Off”. Figure 2 (below) shows the orientation of the DIP switches with
respect to ON/OFF positions.
Default positions for Switches SW1-SW8 are shown in the table on
the following page. Descriptions of each switch follow the table.
