HP DECnet SNA Gateway for Synchronous Transport, V1.4

HP DECnet SNA Gateway for SPD 25.C6.07
Synchronous Transport, Version 1.4
In addition to disk space allocated to HP DECnet SNA
Gateway-ST software, some disk space (approximately
5,000 blocks) should be reserved for any dump files
that may be generated by HP DECnet SNA Gateway-
ST. The location of these dump files is determined by
the system administrator. In addition, each Gateway-ST
configured will require additional disk space (at least 40
blocks (20 KB)) for configuration scripts.
Communications Hardware Requirements
DEC MicroServer
HP DECnet SNA Gateway-ST software runs on the DEC
MicroServer unit, which is supported in the following
forms:
• DEMSA-AA for use with 120V AC power supplies
• DEMSA-AB for use with 240V AC power supplies
The DEC MicroServer has a built-in LAN controller but
needs a suitable connection to connect to the cus-
tomer’s LAN, together with any necessary extension ca-
bles.
The DEC MicroServer uses adapter cables to provide
the necessary interchange circuits at the appropriate
electrical interface types and ISO standard connections
for each synchronous line. One of these cables is
needed for each line used. Table 2 shows the cable
numbers for each of the electrical interface types.

V.35 BC19F-02 ISO 2593
The BS19D-02 cable provides the RS232-D/V.24 inter-
face, but is supplied with an adapter that allows it to be
used for RS232-C as well.
DEC MicroServer synchronous ports do not provide
clock signals; an external clock source (such as a mo-
dem or modem eliminator) is required.
DEC MicroServer-SP
HP DECnet SNA Gateway-ST software runs on the DEC
MicroServer-SP unit, which is supported in the following
forms:
• DEMSB-AA for use with 120V AC power supplies
• DEMSB-AB for use with 240V AC power supplies
The DEC MicroServer-SP has a built-in LAN controller
but needs a suitable connection to connect to the cus-
tomer’s LAN, together with any necessary extension ca-
bles.
The DEC MicroServer-SP uses adapter cables to pro-
vide the necessary interchange circuits at the appropri-
ate electrical interface types and ISO standard connec-
tions for each synchronous line. Table 3 shows the ca-
ble numbers for the electrical interface types supported.

OPTIONAL HARDWARE
Additional adapter cables (with the necessary extension
cables and modems) to make use of additional syn-
chronous lines on the DEC MicroServer, up to the max-
imum defined in the SPD.
SOFTWARE REQUIREMENTS
OpenVMS Operating System for I64, Version 8.2-1 or
8.3 (SPD 82.35.xx)
