PTI Announces Availability of ComLink Communications Packages.ROCHESTER, N.Y.--(BUSINESS WIRE)--Nov. 20, 1995--Performance Technologies Incorporated (PTI PTI - Portable Tool Interface ) announced today that it has begun shipments of ComLink Communications packages. This easy to use software makes PTI's Wide Area Network controllers Plug n' Play-compatible with SunLink communications packages from SunSoft. Users of Sun's suite of communications protocols, such as X.25, PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using , IP, Frame Relay, SNA (Systems Network Architecture) IBM's mainframe network standards introduced in 1974. Originally a centralized architecture with a host computer controlling many terminals, enhancements, such as APPN and APPC (LU 6. 3270, etc., can easily upgrade their hardware from the Sun HSI/S SBus module to one of PTI's high performance, intelligent sychronous communications adapters for the SBus. The SBus Intelligent Communications Controllers provide OEMs, integrators and end-users with an intelligent, two- or four-port, high speed serial commmunications interface. Both modules are proven high speed, programmable, serial controllers that support a variety of protocols used in synchronous and asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. data communication. ComLink supports all SBus platforms running Solaris 2.X. Two models are available now: The PT-ACC332-10528, for use with the PTI's two port WAN controller PT-SBS332, and the PT-ACC334A-10571, for use with PTI's four-port WAN controller PT-SBS334A. Both list for $300. Unlike other controllers, the onboard intelligence (Motorola 68360/CPU32+) and large DRAM arrays of these boards allow them to handle much of the low level communications activities that typically would burden the host workstation or server. This can greatly enhance overall system performance. The two port SBS332, operating under typical protocol overheads, can sustain a 600 Kbps full duplex data rate on each channel, while the four port SBS334A achieves a sustained throughput of over 1Mbps full-duplex on each of its channels. Both boards support a wide array of communication interfaces, including RS-232C, RS-422/449 and V.35. A number of third parties have already ported a variety of specialized communications protocols to the PT-SBS332 and PT-SBS334A. These include HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. , HDLC-NRM, HDLC-LAPB, SDLC (Synchronous Data Link Control) The primary data link protocol used in IBM's SNA networks. It is a bit-oriented synchronous protocol that is a subset of the HDLC protocol. See SNA, DLC and Microsoft DLC. 1. , DCCMP, ADCCP (Advanced Data Communications Control Procedure) An ANSI communications protocol that is similar to the SDLC and HDLC protocols. ADCCP - Advanced Data Communications Control Protocol and CD-2. ComLink now provides users direct support of Sun's "zsh" interface. Customers will find it much easier to write their own communications protocols and integrate the result with PTI's leading edge communications controllers.
