Power Connections
Power is supplied to the desk set from a listed ac adapter. Make connections to the main circuit board
according to the following table:
TS1 Pin # Function
1 N/C
2 N/C
3 Line Signal Connection (–)
4 Line Signal Connection (+)
5 Ground and dc minus or (–)
6 Power (+)10.5 to 16 V dc (lead with white dashed line)
Line Connections
To make the required line connections, a cable with a tinned bare leads stripped to about 3/8-inch or pin
terminal is necessary. With the housing opened, route the lines through the slot in the housing bottom.
Using a small slotted screwdriver, connect the two-wire line to the terminal block position on the main
circuit board labeled
LINE 1
. See the terminal block table above.
Several desk sets can be connected in parallel. The maximum loss between any two desk sets, or
between a desk set and the station, should not exceed 20 dB. Desk sets are shipped with line termination
enabled. With parallel units connected, only the most distant desk set unit should be terminated. Refer
to the SWA Switch Settings Table on page 7.
Line Considerations - Private Circuit
If leased lines from your local telephone company are used between the remote desk sets and the
IDA1000 or similar dc remote adapter, the line provider (Local Exchange Carrier) may request a Facility
Interface Code (FIC) or Network Channel Interface Code (NCI code). End-to-end dc continuity is
required on these private analog circuit lines. The private analog service lines described in the table
below are subject to local availability.
