Function Switch Three
Function switch three is a six-segment DIP switch used to configure the
data interfaces for each channel.
Set to Up (DTE) if the channel is connected to a DTE-type device such
as a CPU port or a terminal (this configures the 2185 interface as Data
Circuit-terminating Equipment - DCE).
Set down (DCE) if the channel is connected to a DCE-type device such
as a modem (this configures the 2185 interface as Data Terminal Equip-
ment - DTE).
LED INDICATORS
Table 3-6 lists the functions of the LED status indicators. Under normal
operating conditions, none of the alarm indicators is illuminated. Refer
to the section entitled Recovery From Anti-Streaming Alarm Condition
in Chapter 4 - Maintenance for the procedure to handle alarms.
