Telenetics 2185
3-20
In this application the main channel of 2185 A is connected to a host
computer through a front-end processor. The data rate is 9. 6 kbps and
the format is synchronous. Since the main channel is connected to a
DTE type device the main channel on 2185 A is set to DTE.
Two subchannels are connected to 2185 B through two networks. One
rout is through a digital network and the backup route is through a com-
mon telephone network. Subchannels one and two of both 2185 A and
2185 B are set to DCE as that is the type of device to which they are
connected. The main channel of 2185 B is set to DTE since it is con-
nected to the controller. Clocking in this network is derived from the
DSU connected to Subchannel One.
The following tables show the correct switch settings for this particular
application and apply to both 2185s.
