(GAINESVILLE, FL -- February 11, 1992) Barr Systems announced that its SNA
|
||
|
|
RJE and 3270 gateways now support access from workstations with
|
||
|
|
asynchronous modems. The feature allows laptops, notebook computers, and
|
||
|
|
other PCs with inexpensive, internal, asynchronous modems to gain dial-up
|
||
|
|
access to mainframes.
|
||
|
|
|
||
|
|
Asynchronous access to the BARR/GATE gateway is provided by the four PC COM
|
||
|
|
ports, and up to four of Barr's new 8-port ASYNC8 adapter boards, for a
|
||
|
|
total of up to 36 ports. Using COM1 through COM4 with internal
|
||
|
|
asynchronous modems provides a very clean and inexpensive solution. This
|
||
|
|
configuration can support a large number of occasional dial-up users. The
|
||
|
|
same gateway can also simultaneously support up to 254 total users on a
|
||
|
|
LAN using NetBlOS, Novell IPX/SPX, or 802.2 Token Ring protocols.
|
||
|
|
|
||
|
|
The ASYNC option supports the IBM-standard Asynchronous Data Link Control
|
||
|
|
(ADLC) protocol, which provides access to the IBM Information Network, and
|
||
|
|
allows the gateway to support both IBM and Attachmate 3270 asynchronous
|
||
|
|
workstations. All of the advantages of the SNA architecture are provided,
|
||
|
|
including error detection and correction, multiple sessions, IND$FILE
|
||
|
|
transfer, HLLAPI support, and even optional RJE.
|
||
|
|
|
||
|
|
Asynchronous modems supporting the V.42 bis compression standard can
|
||
|
|
provide dial-up access at up to 38.4 kbps. This is much faster than
|
||
|
|
existing synchronous dial-up solutions. Barr Systems products also support
|
||
|
|
full duplex communications. This improves performance even during one-way
|
||
|
|
transfers because the required acknowledgements are sent simultaneously.
|
||
|
|
|
||
|
|
The ASYNC option to BARR/GATE sells for $690, and supports up to four ports
|
||
|
|
using internal PC hardware. Up to four ASYNC8 eight-port adapters may be
|
||
|
|
added to the gateway for $1,290 each. Remote workstations require Barr's
|
||
|
|
3270/ASYNC, with a list price of $200 per workstation, or compatible
|
||
|
|
software.

(GAINESVILLE, FL -- February 11, 1992) Barr Systems announced that its
|
||
|
|
remote mainframe communications products now support host connection using
|
||
|
|
the Qualified Logical Link Control (QLLC) protocol to send SNA over X.25
|
||
|
|
networks. The X.25 link can greatly reduce access costs by eliminating
|
||
|
|
long-distance telephone charges.
|
||
|
|
|
||
|
|
Support for X.25 attachment has been added to the existing BARR/SNA RJE,
|
||
|
|
RJE+3270, BARR/GATE, and BARR/3270 products. These were previously
|
||
|
|
available with SNA/SDLC, Token Ring, and coaxial (DFT and 3299)
|
||
|
|
connections. The X.25/QLLC connection operates over Barr's existing
|
||
|
|
RS-232, V.35, and X.21 adapters, or with Barr's PC-SYNC internal
|
||
|
|
synchronous modems. There is no additional charge for the X.25/QLLC
|
||
|
|
software.
|
||
|
|
|
||
|
|
President Tony Barr notes, "We intend to support the full spectrum of IBM
|
||
|
|
connectivity. The X.25 option is an excellent choice for any RJE or 3270
|
||
|
|
environment where the per-packet charges would be lower than long-distance
|
||
|
|
or dedicated line fees." In the Barr Systems implementation, packet costs
|
||
|
|
have been minimized by eliminating all unnecessary SNA frames, and by
|
||
|
|
automatically adjusting packet and window sizes to reduce segmentation of
|
||
|
|
messages.
|
||
|
|
|
||
|
|
The X.25 connection to the host is via the NCP Packet Switching Interface
|
||
|
|
(NPSI), supported by IBM. Barr's SDLC and X.25 communications options
|
||
|
|
support line speeds of up to 384 kbps. In addition, they support
|
||
|
|
full-duplex (DATMODE=FULL) operation, which can nearly double the
|
||
|
|
throughput provided by competing products.
