Introduction
The Digital Business System (DBS) range is a hybrid system allowing both digital key
telephone and analogue telephone handsets.
There is a range of three cabinet sizes. DBS38 , DBS68 and DBS90. These can be used
individually or combined with a second DBS90 to give a range of systems DBS38 , DBS68 ,
DBS90 , DBS128 (DBS90+DBS38) , DBS158 (DBS90+DBS68) and DBS180
(DBS90+DBS90).
The cabinets are supplied empty, except for the power supply, and are configured using
modular cards and equipment options.
This section describes the port types and equipment for the DBS.

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.
Table 7 - Maximum Cable Distances
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.
Cable Maximum Loop Resistance Maximum Length
CCU > ITS 40 ohms 240m
CCU > DSS 20 ohms 120m
CCU > 1AS (A version) 100 ohms 480m
CCU > 1AS (B version) 100 ohms 880m
CCU > PFU 250m
NTTP > CCU 15m

Call Path Delay
The maximum call path delay for each speech link is shown below. The times are in micro-
seconds.
Table 8 - Call Path Delay
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
The DBS works only in Simple Call Routing Mode (SCRM). All PSTN ports can be configured
for SCRM working. ITS and 1AS ports are associated with the SCRM PSTN ports.
