A base connection module providing slide-in connector cards houses and supports circuit cards which make up the Network Support Processor. These cards include a master controller which includes a master processor card, a master memory control card and an Interface Card which connects to a main host computer and to one or more line communications processors, each of which may handle up to 16 data communications lines. A slave controller likewise includes a slave processor circuit card, and a slave memory control circuit card. A series of slide-in memory cards forming a shared memory storage means connect to both the master and the slave memory control circuit cards.
