Advanced Computer Communications Inc, Santa Barbara, California has added an X25 front-end processor for DEC’s MIPS Computer Systems Inc RISC-based DECstation workstations to complement the ones it offers for DEC’s Qbus, Unibus and VAXBI machines. The ACP 3250 X25 front-end processor uses the SCS interface and is designed to enable the workstation to accommodate X25 communication schemes such as TCP/IP, X29 and custom stacks via a programmer’s interface. The X25 protocol resides in EPROM and executes on the front-end, so the performance of the workstation is not degraded by the need to run X25 router or server. Under TCP/IP, the ACP 3250 provides wide area network routing capabilities under the control of a designated workstation. The Multi-Protocol Driver supplied with the ACP 3250 enables it to support X29 terminal packet assembly-disassembly, raw packet level X25 through a programmer’s interface as well as TCP/IP traffic. It uses the same X25 implementation and user-level interface as the ACP 5250 Q-bus, ACP 6250 Unibus and ACP 7250 VAXBI pricessors. It costs $5,250 and is available now.
