Voice Mail Features
This PBX supports Voice Processing Systems (VPS) with DTMF Integration as well as DPT (Digital)
Integration, attached locally and over a network. (→ 1.20 Voice Mail Features)
Parallelled Telephone Features
By connecting telephones in parallel, you can increase the number of telephones connected to the PBX
without adding additional extension cards. (→ 1.10.9 Parallelled Telephone)
Parallel Mode
An SLT can be connected to an APT or DPT that is connected to a Super Hybrid port of the PBX. The
SLT shares the same extension number with the APT or DPT.
EXtra Device Port (XDP) Mode
An SLT can be connected to a DPT that is connected to a Super Hybrid port of the PBX. Unlike parallel
mode, XDP mode allows each telephone to act as an independent extension with its own extension
number.
Digital XDP
A DPT can be connected to another DPT that is connected to a Super Hybrid port of the PBX. Similar
to XDP mode, each DPT acts as an independent extension with its own extension number.
Portable Station (PS) Features
PSs (e.g., KX-TCA255, KX-TD7690) can be connected to this PBX. It is possible to use the PBX features
using the PS like a PT. A PS can also be used in parallel with a wired telephone (Wireless XDP Parallel
Mode). In this case, the wired telephone is the main telephone and the PS is the sub telephone. (→ 1.21

Hospitality Features
This PBX has several features that support its use in a hotel-type environment. Extensions corresponding
to guest rooms can be "checked in" or "checked out" by a designated hotel operator, who can also check or
set wake-up calls, and print out records of guest charges. (→ 1.23.1 Hospitality Features—SUMMARY)
Built-in Simplified Voice Message (SVM) Features
By just installing an optional voice message card in the PBX, simple answering machine services can be
provided. (→ 1.15.8 Built-in Simplified Voice Message (SVM))
Cellular Phone Features (KX-TDA3920 required)
This PBX supports the use of cellular phones and other outside destinations with the PBX. Cellular phones
can be treated as extensions within the PBX, and paired with wired telephones in Cellular Phone XDP
Parallel Mode. (→ 1.29.1 Cellular Phone Features—SUMMARY)
