Cabling Requirement
The cabling between the Central Control Unit (CCU) and each extension is 2 wire, 0.5mm
diameter copper conductor and terminated with a Line Jack Unit (LJU). Use a master LJU for
analogue extensions and a slave LJU for the digital extensions.
The following table shows the maximum cable length from the CCU.
Cabling from the Network Test and Termination Point (NTTP) must also comply with these
requirements.

Over-voltage Protection
Surge arresters are fitted to the PAS, ITS and 1AS ports of the system. If the extension
cabling extends between buildings or runs around the outside of a building, surge arresters
should be fitted at both exit and entry points.
PBX Recall
The DBS can be installed as a host or subsidiary system to suitably approved PBX
equipment.
As a host the DBS will accept timed break recall signals from a PBX connected to a 1AS
port.
As a subsidiary the DBS can provide both timed break and earth recall signalling to the host
from PAS ports.
1AS Port Line Feeding
The DBS is not a through fed system. Line feeding from 1AS ports to connected equipment is
derived internally from the DBS CCU. The maximum current that can be supplied to
extension equipment on 1AS ports is 50mA.
Analogue Extensions
When using separately approved extension apparatus, Panasonic recommend DTMF
signalling. The recall signalling must be timed break. The impedance class of the apparatus
must be class (a) of clause 4.3.2.1 of BS6305:1982.

Power Failure
If installed the batteries inside the CCU will back up the operation of the DBS for a short
time. The precise time will depend upon system size and the volume of call traffic.
Alternatively an external battery may be added to increase the running time in the event of a
power failure.
In addition a number of power fail telephone units (PFUs) can be connected. The CCU will
divert the first few lines to these units if the power and battery backup fails. The number of
PFUs varies according to the CCU used.

Interconnection Of Ports
Warning
Interconnection directly or by way of other apparatus, of ports marked in accordance with
clause 5.2 of BS6301:1989 with ports marked or not so marked may produce hazardous
conditions on the network. Advice should be obtained from a qualified engineer before such a
connection is made.
SAFETY WARNING: See Instructions For Use !
The ports so marked do not provide isolation sufficient to satisfy BS6301. Apparatus
connected to such ports should either have been approved to BS6301 or have previously
been evaluated against British Telecommunications PLC, Technical Guides 2 or 26 and
given permission to attach. Other usage will invalidate any approval given to the apparatus.
Prevention Of Access By The User
The DBS is intended to be accessible only to authorised personnel. There are no user
accessible parts inside the equipment. Failure to prevent such user access will invalidate any
approval given to this apparatus.
Simple Call Routing Mode

ISDN Interface
The DASS II interface and associated equipment allows the connection of Primary Rate
ISDN to the Digital Business System (DBS). A maximum of 30 digital channels can be
connected to any of the DBS systems irrespective of the system size. Connection of the
digital circuits will reduce the number of analogue lines which can be connected to the
system. The tables in the installation manual show which combinations are valid. The
maximum number of DASS channels plus analogue lines can never exceed 48.

DASS II Feature Descriptions
Category 1 & 2 Calls
All calls on the ISDN have a Service Indication Code (SIC code) to allow the network to
determine the call type. The DBS will accept incoming calls with SIC codes 00H , 10H or 12H
only other call types will be refused. Outgoing calls from the DBS use the SIC 10H.
Direct Dial In
The network can send the last digits of the number dialled by the caller to the DBS. This
string can be 1 to 6 digits long dependant upon configuration and the network services being
subscribed to by the user. The DBS will use these digits to route the call to a specific
extension or group of extensions using a look up table.
16
Panasonic Digital Business System - Overview
April 1997
Issue 6
Call Charge Indication
The call charge is sent to the DBS at the end of an outgoing call. This data can be printed on
the call logger and/or optionally displayed on keysets with an LCD.
Calling Line Identity
The calling party’s number or called party’s number can be displayed on a keyset with an
LCD. The Incoming CLI from a caller is called Originating Line Identification (OLI) and the
number returned from the network from a called party is Terminating Line Identification (TLI).
DASS II Detailed Feature Descriptions
Where the DASS II features are different from the analogue equivalent the details are given
below.
Channel Seizure
The DASS channels are analogous to exchange lines and the terms channel and line can be
considered equivalent when discussing calls over ISDN. The method of selecting a DASS
line is the same as for Analogue lines. The two line types can be mixed in line groups, but
caution is required since the dialling method for each is slightly different. When a DASS line
is seized the B channel is set so that incoming calls on the selected channel are rejected.
Dummy Dial Tone
When a channel is selected the DBS will send a dummy dial tone to the internal user. The
tone stops when dialling starts. If no dialling is started during a specified time after seizure
the channel is released and busy tone sent to the user.
Dialling
Dialled digits are stored in the DBS and compiled into a dial message. this is sent to the
network when a send key (#) time-out expires. The send key can be assigned to an FF key.
If no digits are sent busy tone is heard by the user.
The timer restarts after each digit is entered. The time-out can be set by programming.
The # key is used as the send key. Analogue extensions using LD dialling will have to wait for
the time-out since they are unable to dial the send command. When dialling the first press of
# will send the digits entered so far to the line. A second press will act as a DTMF # or
account code terminator depending upon circumstances.
If digits are dialled after the send key is pressed they are stored by the DBS and sent as
DTMF after the called party answers. When using a DASS II channel the speech path is not
established until the called party answers.
17
Panasonic Digital Business System - Overview
April 1997
Issue 6
Call Type
When a call is received the SIC showing its type and capacity required are checked by the
DBS. Calls of a type which are not supported by the DBS are terminated.
DASS Incoming Ringing
Calls without DDI information will ring as if they were a standard analogue line. When A DDI
call is received it will ring as per the DDI settings. If the system is not set to use DDI numbers
and a DDI call is received it will ring as if it were a normal incoming call.
Direct Dial In
The DBS can connect calls directly to extensions using DDI information of 1 to 6 digits sent
from the network. Up to 144 DDI numbers can be specified in a programming look up table to
route calls to an extension or group of extensions. A maximum of 50 groups of 8 member
extensions can be created via programming.
In the DDI look up table each DDI number can only be specified once and route to one
extension or group. Extensions and groups can be the recipient of calls to multiple DDIs by
assignment to these DDI numbers in the table.
An incoming DDI call has priority over other incoming call types at the destination extension,
overriding DISA , private line and other incoming calls.
Delayed ringing does not operate with DDI calls.
Auto answer is always operative for DDI calls regardless of system settings.
DDI to Extensions
When a DDI call is routed to an extension hunting call forward and coverage groups will
operate as normal.

DDI to Groups
When a DDI call is routed to a group hunting call forward and coverage groups are not
available and do not operate.
A extension in a group cannot receive a DDI call under the following conditions.
Off hook
While receiving another call
While being used for programming
The extension to which call forward has been set cannot receive a call
While DND is set
While absence message is set
SLT overload (system cannot drive the ringer on any further SLTs)
While holding an internal or non appearing line and the DDI is also non appearing
A group cannot receive a DDI call under the following conditions.
All members are unable to receive the call
The group is receiving another incoming DDI call which is not yet answered
Incoming DDI ringing is only sent once. If a receiving extension returns to idle after DDI
ringing is sent it will not ring for the missed DDI call.
Auto Transfer / Terminate Of DDI Calls
When a DDI call cannot be routed to its destination, is unanswered or the DDI number is not
recognised it will either be transferred to the operator or terminated depending upon system
program setting.
Sending Of DDI Number On Outgoing Calls
The DDI number of a telephone can be sent to the network with outgoing calls to become CLI
for the receiving party.
When a telephone has multiple DDI numbers assigned to it the DDI number sent is
determined using the following rules.
If the extension has its own DDI and is a DDI group member, extension DDI is sent
If the extension has more than one individual DDI, the DDI look up table is scanned
from 1 to 144 and the first DDI found for the extension is sent.
If more than one DDI group numbers and no extension DDI us set, the DDI look up
table is scanned from 1 to 144 and the first group DDI found for the extension is sent.
DASS II Called Party Busy
When the called party is busy the DBS can pass busy tone to the extension making the call
or terminate the call and pass dummy busy tone to the extension. It is also possible to display
the cause of the busy tone returned from the network on the LCD of a keyset. The action
taken when a called party is busy is specified through programming.

Call Logging Output
The CLI and CCI data sent from the network is sent to the call logger. Condition codes for
incoming and outgoing DASS II calls have been added to the call logging output.
CLI Display
When a call is received the first 16 digits of a callers number can be displayed on the first
line of the LCD on a keyset. If CLI is not supplied by the network the channel number is
displayed similar to the display when an analogue incoming call is received.
When making a call the first 15 digits of the recipient party’s CLI can be displayed on the
second line of the LCD on a keyset if supplied by the network. If this data is not supplied the
dialled number is displayed as for analogue lines.
The number will not be displayed when the call is held, when the second line will display the
line number as for an analogue call.
Confirming Charge Data.
The charge data for the most recent call can be displayed on the LCD of a keyset. When new
CCI is received the previously stored value is replaced with the new one. This data is not
backed up.
The totals provided by the DBS at the operator console are cumulative and are only cleared
when the operator enters the command CONF #95 Ext No. *. See the DBS Operating
Instructions for more detail.
DASS II Relationship With Existing Features
Call Barring
Call barring operates in the same way as analogue lines.
Least Cost Routing
The LCR function will operate on the DASS II channels. However the method of accessing
the networks differ between the analogue and digital lines.
It is recommended that analogue line access be programmed as carrier 1 (NCC1) and DASS
II access be programmed as carrier 2 (NCC2).
When 131 access is used the 131 is sent first with the PIN and caller number are sent after
the network sends the acknowledged signal.
When 132 access is used , 132 and the caller number are sent at one time as a dial
message.

Speed Dialling
Speed dial numbers should be stored in the usual way. When # is stored at the end of the
SSD the DBS will regard this as the send character and send the dial message. When # is
stored in the SSD before the end the DBS will send digits before the # as a dial message and
those after as DTMF after answer. When # is not stored it can be dialled after the SSD
command or the time-out can be allowed to run its course to send the dial message.
Speed dialling after answer will be sent as DTMF.
FLASH is treated in the same way as RECALL
Redial And Save Dial
When used during a DASS II channel the call is terminated, the channel cleared and dialling
sent on the same channel. Settings for flash and auto pause are ignored.
Exchange Line Pause
A pause stored in an SSD before the send command is ignored. Following the send
command the pause is inserted in the DTMF dialling at the stored location.
FLASH
Flash on a DASS II channel will terminate the current call and reserve the channel for
another call whilst presenting the extension with dummy dial tone.
RECALL
The Recall function is not supported by DASS II. Therefore the RECALL key will have no
effect unless set in programming to ‘Release And Re-seize’ in which case it operates as a
FLASH.
Exchange Line Hold And Transfer
When making a DASS II call it cannot be held or transferred until the called party answers.
Hold function and hence transfer are not available until the call is answered and the speech
path established. Before the speech path is established transfer, park hold, conference,
privacy release and call waiting will not function.
When receiving an incoming DASS II call the speech path is established immediately.
Off Hook Signal
A normal incoming DASS II call will off hook signal in the same way as an analogue
exchange line.
A DDI incoming call will not operate off hook signalling.

Other Restrictions When Using DASS II On DBS
The DBS does not accept calls from DTE
DTE cannot be connected to DBS
Network Address Extension ( Sub-Addressing)is not supported
E&M (DC5) is not available when using the CPC-C DASS II card
Voice Announce Unit
Model Number: VB3632
The Voice Announce Unit (VAU) is an optional unit for use with the DBS. It is connected to
digital extension ports. The VAU provides recorded messages to callers, then transfers them
to another extension following the callers’ DTMF dialled instructions.
Each Voice Announce Unit contains two answering circuits each can have a different
message or messages recorded depending upon DIP switch settings. Each circuit is
associated with one DEC port. Circuit 1 for port 1 and circuit 2 for port 2.
The recorded messages and programmed information have a battery backup which will hold
the data for up to 5 days in the event of a power failure once the unit has been installed for
48 hours.
When the VAU detects a call, it answers and plays a recorded message. If the VAU is used
to back up an operator, or group of people, a delay to answer can be inserted, this allows the
original persons time to answer the call if they are available. Recall ringing will override the
delay to answer timer and the call will be answered immediately.
In the event that a caller is using an LD/pulse dialling telephone, or the DTMF level is low,
the VAU will automatically transfer the call to a predetermined extension.

Internal DTMF Dialling From System And Personal Speed Dials
It is now possible to send DTMF signals internally from System Speed Dials and Personal
Speed Dials on the DBS. This will allow single key access to voicemail systems to be set up.
To do this the destination extension is stored, followed by a DTMF send key and the DTMF to
send. The DTMF can include 1 - 9,0,*,# and REDIAL (pause). The DTMF tones are 250ms
mark / 250ms space and the pause time is the voicemail pause timer introduced in v4.0.
When using a memory to send internal DTMF in this way the keypad of the extension is
disabled until dialling is complete and if the extension is a display keyset the LCD is blank.
The blank LCD will keep passwords secret.
When dialling the tones can be audible or silent dependant upon system program setting. If
the memory is sent during a conversation the contents will be DTMF dialled over the speech.
Memories can be ‘chained’ together provided that the total length of the combined memories
does not exceed 24 digits.
When an System Speed Dial is used in this manner it does not increment the System Speed
Dial use counter which can be viewed from the operator extension, this counter is only for
external calls.
The facility can also be used over an E&M link, in which case the DTMF is sent after E&M
answer is received and any stored pause ignored.
This facility will operate to any extension. However if the extension is set to forward to
voicemail it will not operate, thus avoiding a repeating loop to voicemail.
Call Logger Indication Of Held And Transferred Calls
The call logging output has been updated to show DASS II calls and calls which have been
held or transferred.
The new condition codes are shown below:
Condition Code
H
T

Meaning
Call has been held and retrieved or recalled. The time field shows when
the call was retrieved and the duration will shown how long it was held
for. If the caller cleared when on hold the line number will be preceded
by a ‘*’. Type of hold is not detected.
Call has been transferred or held and retrieved or recalled at some
point. This will print at the end of the call where the start time is the time
it was transferred or retrieved and the duration is the time since it was
transferred or retrieved.

180 System Speed Dial Availability
The new versions of software allow for the DBS to be configured for 2 x 90 SSD groups or 1
x 180 SSD group. This is set via programming and requires a power off/on reset to take
effect. Changing this setting will not erase the contents of the SSDs.
The SSD numbering changes dependant upon the mode selected.
With 2 x 90
With 1 x 180
the SSD locations are numbered
the SSD locations are numbered
00~89 in each group
100~189,200~289
Call Charge Range Increased
For meter pulse detection call charging the allowable cost has been increased from 99.9p per
unit to 999.9p per unit. The step controlling the charge remains otherwise unchanged.
Suppression Of Call Forward Indications
It is now possible to suppress the display of call forward indication from the second line of a
keyset LCD and green LED indication on BLF keys, when an extension sets call forward. This
is useful when many users will be setting forward to voicemail and do not want these
indications present.
When suppressed the DND/CF LED on keysets will still be illuminated to indicate call forward
status.
ISDN DDI Group Name Display
The DDI group name can be displayed on the second line of a keyset LCD when an incoming
DASS II DDI call is received by a DDI group. This will clear after answer.
Group name will override CLI display.
Absence Message Entry Without A DSS Console
Absence messages can now be set by the operator extension using the keypad to enter the
characters. Maximum message length is 15 digits.
Call Forward No Answer Setting From Menus On The VB3411LDS
Call forward no answer option is now available from the function menu of the large display
keyset.

The CPC-EX Card
The CPC-EX card is an expanded and enhanced CPU card for the DBS. It replaces the CPCB and CPC-C cards, combining the facilities of both and providing new facilities to further
enhance the functionality of the DBS.
The CPC-EX can be fitted to any existing DBS system, directly replacing the CPC-B or -C
card installed. The memory can be RAM transferred between CPC-B v3.2 or later and CPCEX but not from CPC-C to CPC-EX, so full programming details must be recorded before
upgrading a card where a manual system reprogram is required.
In conjunction with the CPC-EX there is a new range of handsets, which can directly replace
the current range and offer expanded features over the previous models. The new handsets
will only operate with the CPC-EX or later software, earlier handsets will still operate with
CPC-EX.
The following new features are available with the CPC-EX.

They are described below.
EURO ISDN And ISDN Feature Enhancements
The v2 software provides the ability to connect to either DASSII or Q.931 ISDN protocols. In
addition a second digital trunk card may be fitted to double cabinet DBS systems to give a
full 48 ( maximum allowed by DBS ) channels split over two digital ‘pipes’. In this case both
cards must be running the same ISDN protocol. Channels can be split as required between
the two cards up to a maximum of 48.
Systems using DASSII will require a new DASII card with an additional Sync Unit connector
in the master CCU The second unit can be the existing DASSII card or a new card with the
additional connector. All Euro ISDN cards are equipped with the extra connection.
The Euro ISDN protocol supports Sub-addressing and 3.1Khz Audio calls in addition to the
DDI and CLI facilities available with DASSII. Sub-addressing is a DISA like function over the
digital network. Digits are dialled after the telephone number and these are passed to the
receiving system and used to route the call internally. 3.1Khz Audio is a setting which allows
calls requiring limited bandwidth ( modem and fax calls ) to only take up the minimum
required bandwidth and not reserve system resources from calls which require the full
channel bandwidth.
The DDI routing has been extended to include a follow on extension option for each DDI on
the system with the call reverting to the operator if both destinations are unanswered for any
reason.
Call Forward With Group Ringing
Call forward and group ringing are also modified so that extensions in ring groups can set call
forward for personal ( direct to the extension, not the group ) calls and still ring for group calls
which will bypass the call forward.
Ringing Hunting For External Calls
27
Panasonic Digital Business System - Overview
April 1997
Issue 6
External calls can now be made to ring around a hunt group on no answer. Set up the hunt
groups in the normal way, select circular or cyclic and set the member and group no answer
timers to the required settings (16 seconds and 320 seconds give a good ringing cycle ).
Make the incoming calls ring to the first member extension and they will hunt until answered.
.
Operator Call Forward
The Operator Extension can set a call forward for all calls provided the night ring telephone is
set to a port other than 1. If the port is covered by an extension card the system will detect its
presence and in this case a Keyset must be installed, which will lose the ability to call
forward; if the port is one that has no installed card associated with it the system will accept
the setting and let the Operator call forward without disabling any other extension.
Extension Feature Clear
Users sometimes set a feature on their extension and forget which feature it is. By going off
hook and entering 790 at the extension concerned all features set by the user will be cleared.
Extension feature clear from the Operator Extension still operates as before.
Programming Mode From Any Display Keyset
Programming mode can be entered from any display, previously this function was a toggle to
enable and disable programming, now it will immediately enable the Keyset when entered
and disable any previously set Keyset.

Separate DDI table for Night Service
Alternative DDI destinations in Day & Night modes for Busy or No Answer
DDI Ring Group membership increased from 8 to 32 members
DDI Hunt Group, DDI Ring Groups and extensions can be members
DDI calls to the operator extension are now subject to overflow ringing
DDI Night Service Table
The DBS now includes a second DDI table for use in Night Service. The table duplicates the
options available for Day Service and allows a separate DDI ringing scheme to be made
operational out of hours.
Calls directed to the operator telephone will be re-routed to the Night Ring Telephone in Night
Service.
When making calls the DDI sent to network will be the DDI from the table ( Day or Night ) in
use at the time the call is made.
Alternative DDI Destination - Busy / No Answer
CPC-EX v2 introduced and alternative extension option to which a DDI call can be routed if
the primary destination is busy. CPC-EX v2.1 enhances this option by allowing the alternative
destination to be a group or extension.
DDI Ring Group Membership
Membership of the DDI Ring Groups has been extended from the original 8 to 32 members.
DDI Hunt Group
A new Hunt Group type has been added to the software for the exclusive use of DDI calls.
There are and additional 16 DDI Hunt Groups allowing 16 members of each. Members can
be extensions or DDI Ring Groups, and the hunting mode is circular, with no answer or busy
searching. No follow on group or alternative hunting modes are supported. The existing Hunt
Group operation is unchanged
For DDI Ring Groups to be included in a Hunt Group they will require a virtual extension
number to be assigned to reference them by. Extensions cannot be members of more than 1
DDI Hunt Group and cannot be included in a more than 1 Ring Group assigned to a DDI Hunt
Group, but can be individually in the same DDI Hunt Group as a Ring Group in which it is
also a member.
Group membership conditions for normal Hunt Groups are unchanged. (see following
example )
