(2) Note that when determining the total connections on a board, the Network Device
connections are multiplied by a factor of 6. For example, if you have 20 gateway circuits and
32 incoming connections, this would be treated as a total of 20+(32*6)=148 total connections.
The factor is used because Network Device connections take more processing power than the
other types of connections.
(3) The maximum connections per board value includes connections for TCP Print Server,
LPD, LAT Host and TELNET Host connections combined is 128.
Line Options/ESC (or ESX)
The Line Options panel for the ESC and ESX card is used to define one CU that will be used
to communicate to a host CPU. Each CU defined, must have a corresponding CNTLUNIT
definition in the host gen. By default, one Line Options panel (one CU) is offered for each
ESC/ESX card installed. Depending on the hardware model (and the number of Extended
CU FADs installed on the platform), additional CUs may be defined to share the same ESC
interface. Additional Line Options panels may be created by pressing the PF4 key. Depending
on the model, up to 16 Line Options panels may be defined for each ESC card, and up to 64
Line Options panels may be defined for each ESX card. If a Line Options panel is created by
mistake, you can use the PF5 key to delete it or set the Protocol option to ‘None’. Protocols
can be mixed or matched on individual ESC cards, as long as they all use the Channel Path
Filter, or all do not use the Channel Path Filter.
The Line Protocol field on the ESC line panel toggles between None, SNA , SNA with Channel
Path Filter, Non-SNA, Non-SNA with Channel Path Filter, CNC, or CNC with Channel Path
Filter. When used in the SCON products, the protocol options are more limited. If ‘None’ is
selected, the CU defined by this Line Options panel will not be used by LINCS.
Examples of the Line Options panels, set for various protocols follow:
