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.

Important System Data

This is a class A product.

In a domestic environment this product may cause radio interference, in which case the user

may be required to take appropriate measures.

This product has been CE marked to show compliance with the EMC Directive 89/336/EEC

amended by 92./31/EEC and 93/68/EEC.

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.
