Integrated PC Interface (BPCI)
An optional BPCI can be installed inside any 3000-series telephone to provide a USB connection
to a PC with Microsoft
®
Windows
®
Telephony Application Programming Interface (TAPI)
applications.
Information such as ANI, DNIS, and Caller ID data is sent from the digital telephone/BPCI to a
computer to provide information for “pop-up” screens. The Telephone Service Provider Interface
(TSPI) PC software is included with each BPCI.
The BPCI also enables simultaneous Computer Telephone Integration (CTI) and voice features,
without the need of a modem or an extra outgoing line.
The PC Interface (BPCI) cannot be installed in digital phones shared with the Cordless DKT-2004-
CT telephone, DKT3001 single line telephones, or telephones that have Speaker OCA Interface
(BVSU) or Add-on modules.
Headset/Ringer Interface (BHEU)
The BHEU provides interfaces for both a headset and a loud ringing speaker. The optionally used
amplifier in the BHEU enables users to adjust the headset volume with the volume button on their
telephone.
With the loud amplified speaker feature, the speaker amplifies the ringing or voice announcement
of an incoming call. The HESB speaker box is required for the loud ringing speaker and is
normally mounted on a wall near the telephone.
BHEU can be installed in the same telephone that has BPCI or BVSU modules installed.
Speaker Off-hook Call Announce (BVSU)
BVSU-equipped digital telephones can receive Speaker OCA which enables stations to receive
internal calls over their speaker while on another call using the handset. The BVSU is not required
in a telephone to originate OCA calls or in a digital telephone that receives OCA calls through the
handset or headset.
Speaker OCA Interface (BVSU) cannot be installed in DKT3001 telephones or in telephones with
a PC Interface (BPCI).
