A printing press cylinder and a method of manufacturing the same. The ethylenealpha-olefin interpolymer according to the present invention has a CDBI of less than 60%, and comprises at least two fractions in crossfractionation of the ethylenealpha-olefin interpolymer, eluting from 85\xb0 C. Each terminal can be capable of simultaneously supporting a packet-switched connection and a circuit-switched connection with the other terminal via the network as a single logical communication arrangement.
