System features a distributed-intelligence

architecture based on a six-wire bus configuration.
This architecture eliminates the need for bulky main equipment: the

keystations themselves perform the system control functions. The use of
a high-performance CMOS single-chip microcomputer in each
keystation achieves this function.

A fully equipped system comprises eight keystations and one Door
Station, with a maximum bus length of 500 metres (0.5 mm diameter
cable).

Refer to Illustration 1 - System Block Diagram.

A single-chip microcomputer in each keystation controls all operational
facilities of the Commander

E105/208+

system.
An in-built speaker provides keystation tones.
A RISC microcomputer controls all keypad functions.

The station microcomputer’s program and data are stored in 8K words
of ROM and 2K bits of RAM. They control all keystation and data
communication functions. During a power failure, a supercapacitor
back-up protects abbreviated dialling numbers (stored in RAM). This
back-up also allows keystations to be unplugged and moved at will from
point to point.

Introduction to the Commander E105/20& System

General Description

System Communications

A carrier-sense, multiple-access communications protocol with
frequency-shift keying transmission achieves signalling between
keystations on the system bus.

DIP Switches

Several keystation facilities are individually programmable via“DIP”
switches located in the base of the keystation’s housing.

These include:

.

keystation address

.

master page inclusion

.

STD/IDD access

.

exchange line ring assignment

.

pulse or tone dialling

.

auto pause insertion.

System Master Keystation

Every system installation must include a System Master Keystation. It
contains the Hold and Ring Detect Board (HRDB-E), which provides
all the electronics necessary for:
.

exchange line ring detection

.

line holding

.

internal music on hold.

From a user’s viewpoint, the operation of a system master keystation is

identical to that of a standard keystation.

Power and Termination

Unit

The other major component of the Commander

E105/208+

system is
the Power and Termination Unit (PTU). This compact unit houses the
Power and Terminating Board (PTB-E) and Optional Facilities Board
(OFB-E).

The PTU and OFB-E for the Commander E

105/208+

are the same as

that used on Commander E

105/208.

Dial Pad Programming

Several keystation facilities are individually programmed via the station
dial pad. These programming steps are password protected.

Controls keystation operation. The MCU works in conjunction with
other keystations (and the

OFF&E,

if installed) to control the system

operation.
Specifically, the keystation central microcomputer controls the:

.

exchange line interface

.

keystation communications and operation

.

intercom keystation interconnection

.

connection of signal tones to the keystation

.

system option programming.

This process or provides an intelligent interface between the keypad and
the station Microcontroller unit. It provides mapping for all ‘intelligent
keys’, such as DSS/Speed Dial keys and

Centel@

functions keys.

Keystation memory consists of 8K words of ROM (10 bits per word)
and 5 12 words of RAM (4 bits per word).The microcomputer uses the
Random Access Memory (RAM) to store abbreviated dialling codes.

The microcomputer uses Read Only Memory (ROM) to store the
keystation’s operating program.

During brief power down periods, the memory back-up circuitprotects
the abbreviated numbers stored in RAM. This circuit consists of a
supercapacitor (charged ready for use under normal keystation
operating conditions) and associated control circuitry.

When low voltages are detected, the reset circuit transmits an interrupt

signal to the Microcomputer Unit (MCU) and generates a reset pulse
when power is restored.

A DC-DC converter that steps down and isolates bus voltages to
supply the keystation circuit requirements.

Isolates keystation circuitry from the bus.

Introduction

This chapter describes the procedures for installing the Commander
E105/208+ system hardware.

It begins with an Installation Checklist that summarises all the hardware
installation procedures. Each point in the checklist is then covered in
detail, with full installation procedures and additional relevant
information. Where appropriate, an illustration and reference are
provided.

Component

Safety Precautions

Commander

E105/208+

equipment contains a considerable number of

MOS and other static-sensitive components. To reduce the incidence

of premature failure due to static discharge, ensure that you take the
following precautions.

.

Always discharge static from yourself before you handle a printed
board assembly (PBA)

.

Always disconnect power before handling or installing

PBAs

.

Always handle PBAs by the edges

.

Never touch PBA tracks or edge connectors. Contaminents

introduced by fingers can cause corrosion and high-resistance
connections.

.

Never touch components. They are physically delicate and finger

pressure can fracture (but not necessarily break) components

leads.

.

Never attempt to repair power plug-packs in the field. They are
powered from the 240V mains supply and contain hazardous

voltages.

Bus cabling is polarity-sensitive. It is essential that correct polarity is
maintained. Be careful when checking voltages on cabling.

Table 4 - Keystation Voltages

Power Down

To avoid possible damage to keystations, power down the system
before they are connected.

.

Switch off power at plug-pack GPO.

Plug in Keystations

After testing all sockets to ensure the cabling is correct, plug in all
keystations and terminate the Door Station (if required).

Keystation Self Test

In Commander E

105/208+

systems, a self test routine is incorporated in

the keystation software to assist with theirinstallation and maintenance.
The self test covers:

.

speaker

.

tone generator

.

LEDs and keypad operation.

The self test should be performed on all keystations after they are
plugged in.

Test Mode Entry

To place the keystation in Test Mode:
.

Enter the password

The password is:

In1

[71[91 bl

where [n] is the keystation address. Therefore, the password

for keystation 3 is ‘3793

‘.

Page 4-18

Genera/ Procedures

Hardware

lnsfallafion

LED Tests

Audio Circuit Test

The password is only

recognised

when the keystation is completely idle
that is, when:
.

it is on-hook

.

no system activity is taking place

.

all

LEDs

are OFF.

You must enter the password within four seconds of pressing the first
digit. If you do not correctly enter all four digits within four seconds,
then you must re-enter the password from the beginning.

NOTE 1:

The test mode does not check any of the RISC functions,

for example, headset and DSS keys.

NOTE 2:When Test Mode is exited, the keystation is reinitialised,

this will clear all programmed speed dial locations.

Immediately after entering test mode, all of the keystation

LEDs,

except

RISC LEDs, illuminate for one second, then turn off.
This confirms that all LEDs are working properly.
After the LEDS have turned off, the keystation is in keyboard test

mode.

To test that each key is working correctly, refer to

Table 5 - Self Test

Key Sequence and LED Responses. Enter the keypresses in the

sequence shown. The nominated LED will illuminate after you press the

Two outgoing line access classes are available for Commander E

105/

208+

keystations:

.

Class 1 - unrestricted calls

.

Class 2 - local calls only.
Program each keystation’s access class with SW 2.2.
NOTE:

This switch is password protected. Refer to Page 5 10 for
full details of password.

.

To program a keystation for Class 1:

.

Set SW 2.2 to ON.

Class 1 keystations have unrestricted access allowing any number of
digits to be

dialled.

To program a keystation for Class 2:
.

Set SW 2.2 to OFF.

In this mode, all numbers

dialled

are compared to an exception table.
The basis of the table is that all dial input is compared to entries in the
table, and if no match is found the call is barred (i.e. all numbers are
barred, with the exception of..

.)

The exception table consists of two areas: A non-programmable area,
with fixed emergency numbers etc, and a programmable area consisting
of 8 entries of 4 digits each. At default, the programmable table is set to

‘no exceptions’.

Page

5-4

,

---

General Programming Procedure

System Programming

To program entries into the exception table, proceed as follows:

1.

Enter [n][7][9][n+l] (where ‘n’ is the keystation address).

Therefore the password for keystation 3 would be 3794.

2.

Press [MEMORY], followed by the table number

([I]

through to

F31>.

3.

Enter the exception code (up to 4 digits).

4.

Repeat steps 2 and 3 until complete

5.

Go off-hook then on-hook.

Exception table entries may be up to 4 digits long. The more digits
entered, the more restricted will be the exceptions that can be

dialled.

In
the example given below, a Melbourne user is restricted to Melbourne
metro, Port Augusta, Queensland, Wollongong and AMPS (the
example is based on the 10 digit AUSTEL numbering plan).

Table 8 - Example of Exception Table

The example demonstrates that adding more digits to an exception table
entry ‘tightens up’ the number range of available destinations. Entry 2
will restrict calls to Port Augusta, while entry 3

wilI

allow most of
Queensland. To tighten entry 2 to the Sunshine Coast only for example,
the entry wouldbecome

[0][7][5][4].

An entry consisting of a

‘*’

only,

effectively means ‘no exceptions are

allowed’.

To clear an entry:

.

Enter

‘*’

at step 3 above.
The non programmable area of the table contains the following:

13n,013.

lnitialise

and Reset

lnitialise

and Reset

Upon power on, an initialising routine sets up the logical and physical
settings of the keystation microcomputer.

The DIP switches are scanned and internal system flags are set/reset
according to the DIP switch settings.

If a change is ever made to the DIP switch settings, the keystation must
be reset for the new settings to be recognised.

There are two ways to reset the keystation:
.

Power system OFF, then power ON,

or
.

Remove, then re-insert, the keystation’s line cord

.

With either method, wait approximately 10 seconds for the

system to initialise.

Access Class Restriction

The

STD/IDD

barring DIP switch has special protection.

If the setting is changed, a password must be entered on the keypad to
initiate a scan of this switch and to reset it. This procedure prevents
unauthorised personnel changing the keystation access class.

This password is:

bl[71[91

bl

where [n] is the keystation address. Therefore, the password for
keystation 3 would be ‘3793’.

The password is only recognised when the keystation is completely idle
that is, when:
.

the keystation is on-hook

.

no system activity is taking place

.

all LEDs are off.

Refer to page 5-4 for programming of exception table.
Enter the password within four seconds of when you press the first digit.

If you do not correctly enter all four digits within four seconds, re-enter
the password from the beginning.

Exit by going Off-hook.
NOTE:

This password is confidential and should not be told to the
customer or to anyone else outside Telstra.

Functional Tests and Maintenance

Maintenance

General

The amount of maintenance that can be carried out on Commander
E

105/208+

equipment is limited to changeover of the PTU and
replacement of keystation parts. This is due to the susceptibility of the
components to damage by static discharge (especially MOS
components).

To protect faulty assemblies and items such as the power supply, PTU
and keystation, transport them in the protective container supplied with
the new item. Before returning faulty equipment, refer to the section
entitled Repair Procedures at the end of this chapter.

System Plug-Pack

When the power supply plug-pack is diagnosed as being faulty, it must
be replaced with a maintenance spare.

When replacing the system plug-pack, before disconnecting it from the
PTU terminal strip

53,

ensure that:

CAUTION

The system plug-pack is powered from a 240V mains supply and

hazardous voltages are present within.

.

the mains outlet is switched off

.

the plug pack is removed from the outlet.

Power and Termination
Unit

Any fault on the PTB-E requires replacement of the entire PTU.
Any fault on the OFB-E (where fitted) requires that it bereplaced with a

maintenance spare. Do not carry out repairs on site as further damage
to the board may result.

Keystations

Keystation maintenance is confined to replacing the handset, line cord
and HRDB-E board (in the master keystation). To rectify a keystation
PBA or keyboard assembly fault, replace the complete keystation.
