Apollo/Integrated SNA Facility, Technical Data Product Number LAA0A Description The Apollo/Integrated SNA Facility, when used in conjunction with an SNA communications controller, provides communications between an Apollo workstation and an IBM System/370 or compatible mainframe using SNA protocols. The Apollo/Integrated SNA Facility manages the SDLC line or channel connection to the host and emulates the major features of the appropriate IBM cluster control unit using the lower four layers of SNA. The product supports Physical Unit Types 2 and 2.1 (PU 2, PU 2.1), and Logical Unit Types 1, 2, 3, and 6.2 (LU1, LU2, LU3, LU6.2). [Figure 1 (Apollo/Integrated SNA Facility diagram) Caption: none] The Apollo/Integrated SNA Facility supports and is used in conjunction with one or more presentation services: Apollo/Integrated SNA 3270 and Apollo/Integrated SNA LU 6.2. These products allow Apollo workstation users to connect instantly and simultaneously to IBM SNA host computers, access applications and databases, and perform file transfers - all while efficiently and effectively working on local Apollo resident files. The Apollo/Integrated SNA Facility product requires an SNA communications controller, either the Serial Controller- AT communications controller in an AT bus-equipped gateway node, or the Channel Controller-AT communications controllers. The Serial Controller-AT communications controller provides two high-speed serial communication ports (up to 64 Kbits per second) and supports the following interfaces: RS232, RS422/449, and V.35. Line speeds and interfaces can be mixed between two ports without any restrictions. The Channel Controller-AT is a communications controller providing high-speed data transfer (up to 3 Mbits per second) between an Apollo workstation with a PC-AT compatible bus and an I/O map to connect to an IBM System/370 I/O interface multiplexer channel. Features o Apollo/Integrated SNA Facility allows the Apollo workstation to emulate the major features of a physical unit type 2.1 (PU 2.1) using SNA protocols. o Apollo/Integrated SNA Facility supports multiple logical units (LUs) as terminals and printers concurrently. The number of LUs available is 255 per SNA communications controller connection. o The microprocessor-based SNA communications controller offloads communications line activity, resulting in zero CPU overhead on the Apollo workstation when data is not being transmitted or received. o Transparent access to IBM System/370 and compatible mainframes without having to disconnect from existing work. o The Apollo/Integrated SNA Facility functions as a non-dedicated gateway. Depending on the customer's specific application requirements, Apollo/Integrated SNA Facility easily operates on an Apollo workstation while running other Domain applications. o The Apollo/Integrated SNA Facility and Serial Controller AT communications controller support dual lines at 64 Kbps over switched or leased lines. o The Apollo/Integrated SNA Facility and Channel Controller-AT attached to the mainframe support line speeds up to 3 Mbps. o Basic transmission unit size of either 265 bytes or 521 bytes for SDLC links. o Message encoding: supports NRZ (Non Return to Zero) and NRZI (Non Return to Zero Inverted). Functional Specifications When used with the Apollo/Integrated SNA 3270 or LU 6.2, the Apollo/Integrated SNA Facility and SNA communications controller emulate a 3274 cluster controller and can manage 255 SNA sessions per link. The Apollo/Integrated SNA Facility allows communication with an IBM 370 or compatible mainframe running VM or MVS operating systems and ACF/VTAM through an IBM 37X5 communications controller running ACF/NCP. It also allows peer-to-peer communications with other physical unit 2.1 nodes in the network, using LU 6.2. The product includes run-time code to implement LU 6.2 verbs, which means that customers whose LU 6.2 applications already include the LU 6.2 verb calls can run the application directly on the Facility product. The Apollo/Integrated LU 6.2 product is not required in this case. A single Apollo workstation holds a maximum of four Serial Controller-AT communications controllers (total of eight connections). Each Serial Controller-AT communications controller requires one slot. A workstation holds a maximum of two Channel Controller- AT communications controllers (total of 16 connections). Each Channel Controller-AT product requires two slots. The product supports up to eight subchannel addresses, and thereby up to eight emulated PU 2.0 nodes to the host. The Serial Controller-AT communications controller and Channel Controller-AT communications controller can be installed in the same workstation. The Serial Controller-AT communications controller supports synchronous modem speeds up to 64 Kbits per second. The Channel Controller-AT communications controller supports speeds up to 3 Mbits per second. Apollo/Integrated SNA Facility, when used with the Serial Controller-AT communications controller, requires synchronous modems that support the following handshake signals: DTR, DSR, RTS, CTS, CD, RI. Modems must also provide transmit and receive clocks for the SDLC interface and ensure ground isolation between the communications systems. Message encoding: supports NRZ (Non Return to Zero) and NRZI (Non Return to Zero Inverted). Customer Installation Responsibility The product is customer-installable. User installation aids such as an automated installation procedure and the manual "Configuring and Managing the Apollo/Integrated SNA Facility" are provided. Additional assistance can be provided by an HP System Engineer on a time-and- materials basis. For additional information, contact your Hewlett- Packard sales representative. Ordering Information Requires concurrent installation of an SNA communications controller (Serial Controller-AT or Channel Controller-AT). Customer must order LAA0A and one option from media and documentation group.
