COMPOINT-LIB in the TCP/IP network 


Each participant of a TCP/IP network has one unique IP number and can thus be 

identified clearly. These IP numbers are composed of 4 figures in the range from 0 to 255 

(octet) separated by a point: 

Examples: 149.213.48.93 or 109.89.1.3 or 56.3.58.13 

You can distinguish 4 different types of addresses: 

1. Addresses of type A 

For addresses of type A the first octet determines the network address (0 -127) and the 

other three octets determine the PC address. I.e. the participants of such a network only 

have the first value in common, all other values are different (e.g. 121.213.13.22, 

121.122.30.89 , 121.23.111.1, etc.). This type of addressing is only used in very large 

networks as altogether there are 256 times 3 addresses available. 

2. Addresses of type B 

The addresses of type B determine the first two octets of the network address and the PC 

names are distinguished by the two latter octets. Some IP numbers of a type B network: 

139.1.0.1, 139.1.234.89, 139.1.45.9, etc.. The maximum number of network participants is 

determined by 256 times 2 and the first value of the IP number is generally in the range 

from 128 to 191. 

3. Addresses of type C 

The addresses of type C determine the first 3 octets of the network address and 

determine the PC name with the 4 th octet. Please find following some examples of a type 

C network: 101.83.12.03, 101.83.12.243, 101.83.12.120 . The maximum possible number 

of participants in the network is limited to 256 and this way many networks can be address 

with only a few PCs. The typical value range for the first value of the IP number is from 

192 to 223. 

4. Addresses of type D 

For the addresses of type D the four highest bits of the IP number = 1110 and this results 

in a value range of 224 - 239 for the first value of the IP number. The types of addressing 

are called Multicast and are used for more recent IP protocols. 

On a TCP/IP network the COMPOINT-LIB has to be assigned with a clear and correct IP 

number according to the above mentioned classes

Functional principal of the COMPOINT-LIB in the TCP/IP network 

For the communication of 2 participants of a TCP/IP network over different types it is 

decided how the Subnet mask had been defined. Each participant of the network 

determines with this mask which other IP participant can be reached. The target address 

will this way be linked with the Subnet mask bit by bit AND – the result will be compared to 

the target address which is extended by the Subnet mask. The value 0 in the Subnet 

mask means that the address indication will not be analyzed in this place and the value 

255 means that an analysis takes place. 

Please find below some examples: 

Proper address 123.49.89.13 

Subnet Mask 255.255.0.0 

The addresses 123.49.xxx.xxx, e.g. 123.49.200.10 or 123.49.30.3, etc. can be reached 

but not 123.50.200.10 

Proper address 123.49.89.13 

Subnet Mask 255.255.255.0 

The addresses 123.49.89.xxx, e.g. 123.49.89.10 or 123.49.89.3, etc. can be reached 

but not 123.49.200.10 

In order to have LAN connections over the router also a connection over the Subnet mask 

needs to be released and the routing needs to be configured with a default Gateway entry 

over the corresponding router. 


8

Setting up the IP address with DHCP. 


1.) The COMPOINT-LIB is operable 

2.) DHCP needs to be connected for network interface in COMPOINT-LIB 

(default configuration) 

3.) The DHCP has to be available in the LAN segment 

4.) Switch on the COMPOINT-LIB 

Functional principal: 

The COMPOINT-LIB contains all mechanisms of the DHCP (Dynamic Host Configure 

Protocol) and can therefore be assigned to an IP address by a DHCP server. The IP 

address can be firmly assigned (static assignment) or can be variable within an IP address 

space according to configuration of the DHCP server. The additional properties of the 

DHCP such as Lease Time, etc. are completely supported by the COMPOINT-LIB. 

Please find following a typical entry on a Windows NT DHCP server:

Configuration with TELNET 

Configuration of the COMPOINT-LIB 

1.) The COMPOINT-LIB is switched on. 

2.) The IP address is set (and/or known). refer to “Setting of the IP address”. 

3.) The COMPOINT-LIB is not occupied. 

4.) The program “TELNET” is available. 

EXAMPLE: 

The settings of the COMPOINT-LIB need to be controlled. 

1 

Start the program Telnet. You will find it either on the PC in the directory 

“WINDOWS” or it will be available on a system ( OS/2 , Linux ) by entering 

“TELNET" + < ENTER>. You can establish a connection to the 

COMPOINT-LIB by entering the IP address.

1 = Protocol With the selection 1 – A you can determine your proper ISDN protocol settings. All 

parameters which are entered here will be transferred before establishing a 

connection to the AT Emulation of the ISDN board. The first 5 protocols are already 

predefined but they can be overwritten. 

Example 

Protocol 1 = (**TEI=1;) = TEI=1(**DHTC=1;) = 1 virtual channel, (B21) = X.31 D-channel 

Protocol 2 = (**TEI=1;) = TEI=1(**DHTC=2;) = 2 virtual channels, (B21) = X.31 D- channel 

Protocol 3 = (**TEI=1;) = TEI=1(**DHTC=5;) = 5 virtual channels, (B21) = X.31 D- channel 

Protocol 4 = (**HTC=1;) = 1 virtual channel (B20) = X.25 B- channel 

Protocol 5 = (**HTC=10;) = 10 virtual channels (B20) = X.25 B- channel 

Example for a X.31 connection: 

ATE0W1S0**TEI=1;**DHTC=1;B21. 

The AT command sequence ATE0W1S0 will prepend each dialing. 

Important: 

Please also refer to our manual “handbuch_isdn.pdf.pdf“ for further information 

about our AT commands.

Example for application 

Example for application for a COMPOINT - LIB: 

In a subsidiary 3 or more POS terminals shall be connected to a provider via ISDN X.25/ 

X.31. All POS terminals are connected to an existing LAN. At the NTBA of the subsidiary a 

DatexP access 100 service is overplugged. It has 2 virtual channels. If more than 2 

terminals are activated at the same time, the selection shall be performed automatically 

over the B channel (X.25) to the provider. 

Additionally, the provider can reach all 3 terminals for service purposes via Remote.

Under “4 = Protocol“ the protocol 2 had been entered. Here 2 virtual channels are made 

available for the D channel (DHTC=2,X31 = B21). If they are depleted here the reconnect 

function will immediately engage and the B channel (X.25 = B20) will be activated. For all 

terminals you have to enter “192.168.0.100“ as target IP address and “6000“ as target 

port. Further settings for your Outgoings are not required.
