555-233-5061794 Issue 5 October 2002
■ The 7404D phone with messaging cartridge cannot be used with PC
Interface. However, the 7404D with PC cartridge can be used, but only
with Group 1 configurations.
Interactions
■ Data Communications Access
PC Interface uses a digital interface and is not directly compatible with
Data Communications Access, which uses an analog interface. Apply
Modem Pooling conversion if you use these features together.
■ Data Protection
Assign Data Protection—Permanent for use with PC Interface for data
communications.
■ Host Computer Access
Both PC Interface and Host Computer Access use digital interfaces. These
features are compatible and Modem Pooling conversion is unnecessary.
■ ISDN-BRI
Each card can have its own separate phone or voice-calling device. A
phone does not require special application software on the PC. However, a
handset or headset alone requires special application software.
■ Modem Pooling
Use Modem Pooling if you use PC Interface to place calls to, or receive
calls from, off-premises stations over analog trunks.
Personal Station Access
Personal Station Access (PSA) allows users to associate the preferences and
permissions of their telephone with any other telephone of the same type.
PSA makes it convenient for different users to use the same bank of phones at
different times. For example, several telecommuting or hoteling employees can
use the same office on different days of the week. The employees use PSA to
“associate” with the office phone — that is, make the terminal “theirs” for the day.
Calls an employee originates from the station are recognized and displayed as the
employee’s calls, and calls routed to the employee’s extension route to the voice
terminal “associated” with that extension.
