If it  is,  proceed  to  the transfer step, otherwise initiate communications with the first system to obtain the data requested.  Upon receipt of the data requested from the first system, store the data in the data cache.  Then update a plurality of pointer tables, each pointer table being associated with a corresponding memory access arrangement,  including a sequential memory access arrangement and a direct memory access arrangement, with data cache address information indicating where the data resides within the data cache.   The data is  then transmitted  to  the  requesting  subsystem  of  the  second system in accordance with a predetermined protocol thereby resulting  in  a  faster  communication  system between  the first and second system.
