Table 32. Configuration Parameter List - TG Characteristics (Connection
Network) (continued)
Parameter Information
Parameter
Cost per byte
Valid Values
0 to 255
Default Value
0
Description
This parameter expresses the relative cost of transmitting a byte over the associated
TG. The units are user-defined and the assigned value should reflect the actual
expenses incurred for transmitting over the TG relative to all other TGs in the network.
A value of zero means that bytes may be transmitted over the TG at no additional cost.
Higher values represent higher costs.
Parameter
Security
Valid Values
Nonsecure – all else (for example, satellite-connected, or located in a nonsecure
country).
Public switched network – secure in the sense that route is not predetermined.
Underground cable – located in secure country (as determined by the network
administrator).
Secure conduit – not guarded, (for example, pressurized pipe).
Guarded conduit – protected against physical tapping.
Encrypted – link-level encryption is provided.
Guarded radiation – guarded conduit containing the transmission medium; protected
against physical and radiation tapping.
Default Value
Nonsecure
Description
This parameter indicates the level of security protection associated with the TG. If
security attributes other than the architecturally-defined ones are needed, one of the
user-defined TG characteristics may be used to specify additional values.
Parameter
Propagation delay
Valid Values
v Minimum LAN – less than 480 microseconds
v Telephone – between .48 and 49.152 milliseconds
v Packet switched – between 49.152 and 245.76 milliseconds
v Satellite – greater than 245.76 milliseconds Maximum
Default Value
LAN
Description
This parameter specifies the approximate range for the length of time that it takes for a
signal to propagate from one end of the TG to the other.
