Indicators
Network
This three-color indicator shows the receiver’s
operating status. Green indicates a signal at the
receiver (either customer data or zero suppres-
sion). Amber indicates signal is present, but re-
ceived data is idle or out of service. Red
indicates an insufficient signal for the receiver
to operate properly.
Tx Data
This three-color indicator shows the status of
the transmitted data. Green indicates marks.
Red indicates spaces. Amber indicates alternate
marks and spaces.
Rx Data
This three-color indicator shows the status of
the received data. Green indicates marks. Red
indicates spaces. Amber indicates alternate
marks and spaces.
Loop Test
This indicator show the loop status of the unit.
Amber indicates the unit is in loop mode.
When the indicator is Off, the unit is not in
loopback.
Loopbacks
Channel Loop
This loop
is acti-
vated by
the reversal of the simplex, 20 mA sealing cur-
rent. This is a unidirectional loop that ignores
the DSU transmit data and retransmits the re-
ceived DDS data. Receive data is unaffected
and circuit CF is forced Off.
Data Set Loop (Non-latching)
This loop is activated by the receipt of at least
four consecutive loop commands and remains
looped as long as each third pattern byte is the
loop command. It returns to normal operation
after at least four pattern bytes that are not the
loop command. This is a unidirectional loop
that retransmits the DSU received data on the
DSU transmit data. Receive data is unaffected
and circuit CF is Off.
V.54 Channel Loop (Annex B: RDL)
This loop is activated by the receipt of the V.54
loop command. This loop is unidirectional and
returns the DSU receive data to the DSU trans-
mit data, and subsequently the DDS transmit
data. Receive data is unaffected.

Pre-Installation Information
All direct connections to DDS lines must be
made using standard plugs and jacks.
Before connecting the unit, inform the
local telephone company of the following
information.
Wallmount Installation
Using Screws
1 Select a place close to a 115 VAC outlet with
clearance for the signal and power cables.
The indicators and switches should be easily
accessible.
2 Vertically place two #6 screws 3-13⁄32
inches apart at the selected place. Leave the
screws out about an eighth of an inch.
3 Place the upright unit over the screws until
the holes engage and slide the unit down un-
til it locks.
Connections
DDS Network Connection
The network
DDS facility
interface is
an RJ-48C
(8-pin) modu-
lar jack with the
following
pinout.
RS-232 Port Connection
The RS-232 connector is a standard DB-25 fe-
male, configured as a DCE port.
The RS-232 pin assignments are shown below.
Only circuits used by the unit are listed. All un-
balanced bipolar inputs and outputs meet RS-
232C physical and electrical specifications. The
asynchronous mode is ITU V.22 compliant.
Power
Plug the connector from the power supply into
the unit. Plug the transformer into an appropri-
ate outlet. This applies power to the unit.
