When you use the order wire system as a voice circuit, you dial a
preset number (station 1 code) to call someone at a remote
terminal. When you use the system as a data circuit, you dial a
different number (station 2 code) to call the same remote termi-
nal to set up a data communications path.
Here is how the data circuit works:
1.
Select channel 1 on the 41096 panel, then pick up the handset and
call the remote terminal (station 2 code). At the remote end, the
00330 order-wire terminal answers your call and operates an
M lead driver that opens a communications channel through the
44214 9600 BPS Modem.
2.
Select both channels 1 and 2 on the 41096 panel. This connects
your computer and external modem to the system. At the same
time the optical coupler (O.C.) circuit disables the sidetone in the
00330 order wire terminal so that the modem does not receive its
own data.
3.
Hang up the handset and start sending or receiving digital data.
4.
When you finish, press the # key to disconnect the modem at the
remote terminal. Release the channel 2 push button. You can ei-
ther release the channel 1 push button or leave it pushed in since it
is used for both voice and data communications.

The 05547-03 option includes the B15-00331-00 DTSS3ON
Order Wire/PABX Interface (Off-Net) Assembly. This option
allows world-wide off-net access to virtually any telephone in the
world. The DTSS3ON allows any station in the order wire
system to dial an access line direct to a central office or through
a PABX, then dial out through the public-switched telephone
network (PSTN). In the same manner, an outside party can dial
into the order wire system and selectively dial any station
desired.
