3.1 Connecting the ATI-D-1PT
•
Route the necessary cabling, and connect the ATI–D–1PT device between the ExecuMail system and the digital
station ports per the connections detailed in the diagram shown on the next page.
•
Use one-pair (two-wire) cable for all connections.
CAUTION
Be careful when connecting the wiring between the DXP Plus and the ATI–D–1PT. Be sure to connect
the digital station port to the COMMON EQUIPMENT jack on the ATI–D–1PT. Damage to the
ATI–D–1PT could occur if you mistakenly connect to the IST jack.
•
A grounding wire is not required for operation; however, one is desirable for decreasing radio frequency
interference and electrostatic discharge susceptibility. The ATI–D–1PT provides a ground stud on its housing
for this purpose. Connect a #6, insulated, solid copper wire between this ground stud and a reliable earth
ground.
•
Inspect the wiring to verify that you have connected it properly.
CAUTION
Do not connect an industry-standard telephone in parallel with (bridged across) the ExecuMail
equipment on the industry-standard side of the ATI–D–1PT. Such a connection will cause the ExecuMail
equipment to operate improperly.
3.1.1 Verifying Proper ATI–D–1PT Connection
Use a voltmeter to check for the presence of voltage on the ATI–D–1PT IST jack.
1. Be sure wiring between ATI-D-1PT and common equipment station ports is installed.
2. Measure for DC voltage on IST jack:
•
Measure between TIP leads and grounding stud on DXP Plus common equipment cabinet.
•
Measure between RING leads and grounding stud on DXP Plus common equipment cabinet.
•
Measure between TIP leads and RING leads.
The measured voltages must be within the limits detailed on the following table.
Measurement Voltage
Tip to Ground – 1 to + 1 VDC
Ring to Ground – 27 to – 38 VDC
Tip to Ring + 28 to + 37 VDC
The TIP lead is positive with respect to the RING lead.
