The hardware configuration for CAMPS is an integral
part of a total system concept which alo includes software
and operational procedures. The system functions are
allocated between hardware, software, and firmware
and partitioned so as to provide the optimum implementation
of the CAMPS systems.
The allocation of functions between sysem elements
has resulted in the hardware configuration described
in this section. This configuration has been further
partitioned into well-defined sub-systems or sub-assemblies.
Fig. 4.1.1-1 shows the CAMPS Hardware Configuration
for the Main Ste equipment. The major elements of
the configuration are:
a) Distribution equipment
b) TDX-systems
c) LTUs (Channel Unit)
d) Processor Units
e) Disk Systems (Channel Unit)
f) Watchdog Processor

.1.1.1 C̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲ ̲E̲l̲e̲m̲e̲n̲t̲s̲
This section gives a more detailed specification of
the six configuration elements as defined in sect.
4.1.1.
4.1.1.1.1 D̲i̲s̲t̲r̲i̲b̲u̲t̲i̲o̲n̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲
The data channels connecting the CAMPS Main Equipment
with the indivdual terminals/external circuits are
named Data Exchange Channels.
The individual channels are transmitted to a terminal
or an external circuit using distribution equipment
determined by the channel application. The distribution
equipment is proiding the adaption necessary for the
transmission of each data channel.
The distribution systems can be categorized into 5
categories.
The characteristics and the applications of each category
are shown on fig. 4.1.1-2.
Each channel is conneced in the Main site at the Standard
CCITT V24/V28 interface of the LTUs/LTUXs.
As indicated on the figure 4.1.1-2 part of the distribution
equipment is placed in the MAIN SITE racks.
Fig. 4.1.1-2…01…D̲i̲s̲t̲r̲i̲b̲u̲t̲i̲o̲n̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲
4.1.1.1.2 T̲e̲l̲e̲c̲o̲m̲m̲u̲n̲i̲c̲a̲t̲i̲o̲n̲ ̲D̲a̲t̲a̲ ̲E̲x̲c̲h̲a̲n̲g̲e̲ ̲(̲T̲D̲X̲)̲
The TDX equipment is used for interconnection of individual
data exchange channels with the Processor Units.
The interfaces of te data exchange channels in the
TDX-system are standard CCITT V24/V28 circuits of the
LTUX modules, see fig. 4.1.1-3.
Each LTUX module is able to interface 1, 2 or 4 data
exchange channels dependent on channel specifications,
and each TDX Crate asembly contains max. 2 LTUX modules.
Each TDX Crate assembly is switched to one of the two
TDX Buses. The switching is controlled by the Watchdog
Processor through the Configuration Control Bus (CCB).
The switching is performed by the BSM-X-modue and the
interconnection to the buses are done by a TDX-outlet
on each bus.
A TDX Bus links together all the functional elements
of the TDX System. The Multiplexing Scheme of the
TDX Bus is driven and controlled by the TDX controller.
All the onnected data exchange channels of the LTUXs
are polled and incoming/outgoing data are transferred
to/from the Processor Units by the TDX Interface Adapters
(TIAs) and the Supra/TDX Interface Modules (STI) placed
in the Processor Units.
The TDX cntroller of a TDX Bus is placed in one of
the Connected TDX Crate assemblies.
The Processor TDX I/F is able to communicate with the
two TDX Buses through the two TIAs.
The two TDX Buses are thus fully redundant.
Fig. 4.1.1-3…01…T̲D̲X̲ ̲S̲y̲s̲t̲e̲m̲
4.1.1.1.3 L̲T̲U̲s̲
The LTUs are front-end modules used for interconnection
of individual data exchange channels with the Processor
Units.
The interfaces of the data exchange channes in the
LTUs are as recommended by CCITT in the V24/V28 standards.
Each LTU module is able to interface 1,2 or 4 data
exchange channels dependent on channel specifications.
The position of the LTUs in the CAMPS Main Site Equipment
is shown on ig. 4.1.1-4.
An LTU module is positioned in the Channel Unit and
is connected to the two I/O Buses A and B. I/O Bus
A is connected to the Buses of Processor Unit #1 (PU
#1) by the Data Channel link A. I/O Bus B is connected
to PU #2 by the DataChannel link B.
The LTU is switched to one of the two I/O Buses A or
B by being claimed through the Bus. An LTU is thus
switched to one of the buses at a time. Each LTU has
dual Power Input, as power is supplied by the power
supplies of both I/-bus A and I/O-bus B. Normally,
the load is shared by the two power buses, but one
power bus is able to supply the total current to the
modules connected to the bus.
The LTU's buffer blocks data transferred from the PU
and conducts the transmisson on the data exchange channels.
Received data blocks are stored in the LTU. The PU
transfers data from the LTUs governed by the interrupt
requests delivered from the LTUs.
Fig. 4.1.1-4…01…L̲T̲U̲s̲
4.1.1.1.4 P̲r̲o̲c̲e̲s̲s̲o̲r̲ ̲U̲n̲i̲t̲s̲
The CAMPS Main Site equipment contains two identical
Processor Units (PUs), see fig. 4.1.1-5. The two PUs
are placed in redundant elements in the confiuration.
One set of redundant elements is composed of PU #1,
Data Channel A, the Channel Interface Adapter (CIA-A)
and I/O Bus A (included the connected Power module).
The other set of redundant elements is PU#2, Data Channel
B, CIA-B and I/O-Bu B.
Each Processor Unit is composed of:
- 3 Central Processing Units (CPUs) for parallel
program execution.
- 2 Random Access Memories (RAMs) forming 256K words
of working storage.
- 1 Supra-TDX Bus Interface (STI) interfacing the
PU to twoTDX Bus Interface Adapters (TIAs)
- 1 Memory Mapping Unit (MAP) which together with
1 Map Interface Adapter (MIA) performs different
central functions in the PU, such as:
1) Logical to Physical Address translation
2) Interfacing the PU to te CU via the Data Channel
3) Generating timing signals and servicing of
interrupts to the CPUs
4) Controlling a V24/V28 communication port to
which the Operator Console is connected.
5) System Boot Load
- 2 TDX Bus Interface Adapters (TIs) interfacing
the STI to the two TDX Buses.
4.1.1.1.5 M̲a̲s̲s̲ ̲S̲t̲o̲r̲a̲g̲e̲ ̲D̲i̲s̲k̲s̲
Three disk assemblies are included in the CAMPS Main
Site equipment.
Each assembly is composed of a disk drive unit including
a disk pack, a Disk Cntroller Adaptor (DCA) and a Disk
Controller.
The Disk Controller modules are positioned in the Channel
Unit (CU) and are connected to the two I/O Buses A
and B, see fig. 4.1.1-6.
I/O Bus A is connected to the Buses of Processor Unit
#1 (PU #1)by the Data Channel link A. I/O Bus B is
connected to PU #2 by the Data Channel link B.
The Disk controller is switched to one of the two I/O
Buses A/B by being claimed through the Bus. A Disk
assembly is thus switched to one of the buses at a
ime.
The Power Buses of I/O Bus A and B are added together
on the Disk CTRL module. Normally, the load is shared
by the two power buses, but one power bus is able to
supply the total current for the modules connected
to the bus.

4.1.1.1.6 W̲a̲t̲c̲h̲d̲o̲g̲
The Watchdog is composed of a Watchdog processor (WDP)
and a set of control adaptors, see fig. 4.1.1-7.
The WDP is contained in a self standing Crate Assembl.
Each control adaptor is placed in the unit/crate under
control.
The Control adapter collects the status monitoring
signals of the Unit/Crate and is able to execute the
switching functions, which are communicated from the
WDPU in order to perfrm configuration control.
The Control adaptors communicate with the WDPU by Configuration
Control Bus (CCB).
In addition to the CCB, two WD control channels are
used for the exchange of on and off-line diagnostic
and control information. The to WD control channels
connect the WDP with PU #1 and PU #2.
The VDU and Printer of the CAMPS Main Site Engineering
position are connected to the WDP.
