2.2 DESCRIPTION
The Model 2701 receives channelized G.704 (n x 64kbps) or clear
channel E1/G.703 (2.048-Mbps) data from the telco's digital data net-
work. The Model 2701 terminates the G.703 telco interface and con-
verts the data for transmission to a user-oriented serial [X.21, V.35,
and EIA-530 (V.36/RS422)]. The 2701 can connect to a Router, FRAD,
PABX or Multiplexer over its serial interface at nx64kbps data rates up
to 2.048 Mbps.

3.0 CONFIGURATION
The Model 2701 features configuration capability via hardware DIP
switches. This section describes all possible DIP switch configurations
of the Model 2701.
3.1 DIP SWITCH CONFIGURATION
The Model 2701 has two sets of internal DIP switches that allow
configuration for a wide range of applications. The sets of switches are
accessed from the underside of the 2701. Figure 1 (below) shows the
location of the DIP switches on the bottom of the printed circuit board.
The Model 2701 DIP switches (Switch Sets 1-2) can be configured
as either “ON” or “OFF”. Figure 2 (below) shows the orientation of the
DIP switches with respect to ON/OFF positions.
