    The LC board works best when the entire 64 KB of network buffer memory is enabled for operation. Some option boards and system configurations do not permit the allocation of this amount of memory. Network performance is slower when you select 32 KB or 2 KB, but you can use the LC board in configurations where address space is at a premium.
