1 S̲C̲O̲P̲E̲
Based on references 3.1, 3.2, 3.3, and 3.4 a design
of the expansion of the CAMPS with the remote terminals
(CRT) has been worked out. The equipment breakdown
is presented in Appendix A.

The CAMPS Remote Terminals (CRT) serves the purpose
of making V24 connections between the main sites and
the remote sites. Mainly to support 4 terminals (VDUs
and MSPs), one OCR and three auxiliary channels per
remote site. Thus 8 channels connects each remote
site to the related main site (Ref. to fig. 4.1).
This does not mean an expansion in the max. connectivity
of each CAMPS-site specified in CPS/210/SYS/0001 fig.
3.4.1.7.1.
The feature is obtained by using statistical multiplexers
(Stat. mux) in each end of the purchaser supplied crypto/modem
lines.
On the main sites, the connection to the Main CAMPS
is made in the CRT Line termination racks, containing
the LTUXs, crates etc. The wiring diagrams on figure
4.1 does not represent the physical connections.
On the remote sites, the connection to the terminals
is made by opto-links and the connections for the auxiliary
channels and the OCR are V28(L/L) links.

5.1 C̲R̲T̲ ̲T̲E̲R̲M̲I̲N̲O̲L̲O̲G̲Y̲
5.1.1 C̲o̲n̲n̲e̲c̲t̲i̲v̲i̲t̲y̲
Referring to ref. 3.3 Annex A, the total CRT connectivity
is equal to the largest number of terminals (channels)
that can be connected. This is settled by the total
number of stat.mux. channels. Thus 50% connectivity
is:
23 sites x 8 channels x 0,5 = 92 channels.
This corresponds to the number of Opto Mux/Demux Transciever
(OMDT) links.
5.1.2 A̲u̲x̲i̲l̲i̲a̲r̲y̲ ̲C̲h̲a̲n̲n̲e̲l̲s̲
Auxiliary channels are those which are connected to
an LTUX on the main site and terminated with a V28(L/L)
adaptor on the remote site.
5.1.3 S̲e̲p̲a̲r̲a̲t̲e̲ ̲C̲h̲a̲n̲n̲e̲l̲s̲
Separate channels are those which are terminated with
V28(L/L) adaptors on both main and remote sites. These
are implemented only where the LTUX capacity is insufficient
or where option 2 is used (section 5.3.1. a) ii)).
5.2 I̲T̲E̲M̲ ̲D̲E̲F̲I̲N̲I̲T̲I̲O̲N̲S̲
5.2.1 V̲2̲8̲(̲L̲/̲L̲)̲ ̲A̲d̲a̲p̲t̲o̲r̲s̲
Each V28(L/L) adaptor (L̲ow Level/L̲ong Distance) supports
4 channels by converting 2 V24 interchange circuits
(CR choise) in each direction:
103 Transmitted Data
104 Received Data
105 Request to send
106 Clear to send
107 Data Set Ready
108.2 Data Terminal Ready
5.2.2 S̲t̲a̲t̲.̲M̲u̲x̲.̲(L)
The statistical multiplexers are 8 (V28/DCE) asynchronous
channel units with one (V28(L)/DTE) modem line. (Maximum
driving distance approximately 15 meter).
The stat.mux./crypto interface will contain at least:
101 Protective Ground
102 Signal Ground
103 Transmitted Data
104 Received Data
114 Transmitter Signal Timing Element
115 Receiver Signal Timing Element
of the V24 interchange circuits.
By means of a protocol on the synchronous line between
the stat.mux'es, data transmission-error protection
is obtained.
A flow-control function will handle any peak-load effects
of input-data from CAMPS/CRT equipment.
5.2.3 O̲M̲D̲T̲
The Opto Mux./Demux transceivers are one channel units,
delivered in two versions. One for crates and one
for mounting inside the terminals. (ref. to note 3
p. 12).
5.3 C̲R̲T̲ ̲D̲E̲S̲I̲G̲N̲
The CRT design is based on the idea of a flexible,
uniform design for all sites, by placing the CRT, main
location equipment in a separate TEMPEST-rack.
5.3.1 F̲u̲n̲c̲t̲i̲o̲n̲a̲l̲ ̲P̲r̲i̲n̲c̲i̲p̲l̲e̲s̲
The remote terminal concept provides the following
possibilities:
8 channels are transmitted to each remote site from
the related main site.
a) Thus, 1 channel saved for an OCR-option and 7 channels
which are used as follows:
i) Primarily, the 7 channels are used for transmission
of CAMPS-channels (LTUX connection on main
site).
In the remote site 4 of these channels are
terminated with OMDTs for opto-cable connection
to the terminals, and 3 are terminated with
V28(L/L) adaptor for connection with electrical
cables (auxiliary channels).
ii) Secondary (option 1) it is possible to implement
a changed configuration, where up to 3 auxiliary
channels are disconnected from CAMPS in the
main site end and used for separate channels.
b) On the main site, the remote terminal equipment
typically includes one LTUX per remote site (4
channels).
i) Primarily these 4 channels are connected to
the stat.mux. and used for transmission to
the remote site.
ii) Secondary (option 2) it is possible to implement
a changed configuration, where the stat.mux.
is disconnected, and the LTUX channels are
used for expanding the number of connected
terminals in the main site. The changed channels
are to be connected by optical cables.
5.3.2 R̲e̲c̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲
5.3.2.1 O̲p̲t̲i̲o̲n̲ ̲1̲,̲ ̲C̲o̲n̲v̲e̲r̲s̲i̲o̲n̲ ̲o̲f̲ ̲A̲u̲x̲i̲l̲i̲a̲r̲y̲ ̲C̲h̲a̲n̲n̲e̲l̲s̲ ̲t̲o̲ ̲S̲e̲p̲a̲r̲a̲t̲e̲
̲C̲h̲a̲n̲n̲e̲l̲s̲
The option is made feasible by addition of V28(L/L)
adaptors in the main site. These added adaptors (and
crates etc.) may be placed in the rack during normal
operation. Thus, a configuration change is implemented
by adding the needed cables.
5.3.2.2 O̲p̲t̲i̲o̲n̲ ̲2̲,̲ ̲C̲o̲n̲v̲e̲r̲s̲i̲o̲n̲ ̲o̲f̲ ̲R̲e̲m̲o̲t̲e̲ ̲C̲h̲a̲n̲n̲e̲l̲s̲ ̲t̲o̲ ̲L̲o̲c̲a̲l̲ ̲C̲h̲a̲n̲n̲e̲l̲s̲
The option is made feasible by addition of opto power
supplies to the CRT TDX-crates. The OMDTs can not
be placed in the racks during normal operation, so
the option may be implemented by transferring the remote
site OMDTs to the main site along with the terminals.
Thus, a configuration change is implemented by removing
the unwanted cables, transferring the OMDTs and adding
the needed opto-cables.
5.3.3 G̲e̲n̲e̲r̲a̲l̲ ̲o̲n̲ ̲O̲p̲t̲i̲o̲n̲s̲
A summation of all equipment needed to implement the
functions and options mentioned above is shown in the
