2 Installation Manual
We are confident that it will provide your customer or client with many years of
dependable service.
This Voice Processing System was especially tailored for the American environment.
For example, it can be configured for English, a second language, or a third language:
System prompts—Recorded at the factory in English
User 1 prompts—Record in any language you like
User 2 prompts—Recorded at the factory in Spanish
These prompts guide subscribers and non-subscribers through specific VPS
operations.
In addition, the VPS supports many other languages through the use of Custom
Service menus. These can be used to greet outside callers who merely need to be
guided to a destination (such as an extension, a mailbox, or a fax machine). Many
languages can be supported as there are 12 keys on a touchtone phone and you can
record up to 100 Custom Service menus. One twelfth of these menus can be recorded
in one language if you desire. Another twelfth can be recorded in another language,
and so on. Thus callers can be guided entirely in their native languages. For a multi-
cultural United States, Custom Service is a truly powerful feature. Please see "Custom
Service" in Appendix A1 SYSTEM FEATURES for more details.
Note
This product is only for connection behind a suitable PBX and should not be connected
directly to the network.

Installation Manual 3
List of Enhancements
Compared to the KX-TVS120/KX-TVS220/KX-TVS320 Voice Processing System, these
models are enhanced by the following new features:
•Personal Custom Service
Allows a subscriber to set the following Custom Services in his personal greeting
(Personal Custom Service):
•Transfer to Mailbox
•Transfer to Extension
•Transfer to Outside
•Custom Service
•VM Service (Voice Mail Service)
•AA Service (Call Transfer Service)
A caller can select a desired service from those above while listening to the personal
greeting or recording a message. (See page 262.)
•Subscriber Tutorial
When a subscriber accesses his mailbox for the first time, the VPS guides him to set
up the mailbox with some Help messages. Simply by following the messages, he can
set up these items:
•Password
•Owner’s Name
•Personal Greetings (No Answer Greeting/Busy Greeting/After Hours Greeting)
(See page 267.)
•Call Transfer to Outside
Enables the VPS to transfer a call to an outside line from the following services:
•Custom Service
•Call Transfer Service
•Personal Custom Service
•Caller ID Callback
(See page 247.)
•DID Call Routing
As well as Caller ID Call Routing, up to 200 DID numbers can be assigned to be
automatically forwarded to a desired destination. The VPS automatically forwards
calls from the assigned DID numbers to a programmed extension, mailbox (including
System Group Distribution List) or Custom Service. (See page 249.)
•Toll Saver
Allows a subscriber to check his mailbox from a pre-assigned DID/Caller ID number
without necessarily making the VPS answer the call. Without Toll Saver, the VPS will
always answer the call and therefore he will incur toll charges. With Toll Saver, the
VPS can let him know that there are no new messages without answering his call.
(See page 318.)
•Improvement of System Security
By default, the System/Message Managers cannot access the VPS from their
telephones until the System Administrator enables the relevant settings and sets a
password for access. The System/Message Managers always need to enter this

4 Installation Manual
password to access the VPS. (See page 332.)
The System Administrator can also choose to set a default password for subscribers’
mailboxes. If this setting is enabled, a default password is automatically assigned
when mailboxes are created (See page 333.)
•Additional PBX Connectivity
Allows the VPS to be connected to a KX-TDA/KX-TAW series PBX to enable new
features such as One-Touch Two-Way Transfer. (See page 347.)
•New Utility Commands
The following utility commands have been added:
•TURN (See page 220.)
This allows you to easily turn off and turn on System and User prompts.
•PREP (See page 221.)
This allows you to visualize Personal Custom Service menus.
