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.
