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.

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.

Equipped with the same high performance microcomputer as the
keystdtions, the OFB-E contains the required intelligence for bus
communications and control functions for the optional features.
The OFB-E is connected to the PTB-E via a flat cable.
Input power is supplied to the PTB-E via a double-insulated,
mains-
operated, in-line plug-pack.
During a power failure, exchange line calls can still be made and
received at a specially provided two-wire telephone that is automatically
switched across the first incoming exchange pair.
The Door Station is a compact unit incorporating a speaker and
microphone. A Door Station provides two-way communications
between any unsupervised area and a keystation.
