X.25 PAD-8 - Black Box Network Services

X.25 PAD-8
Connect as many as eight
asynchronous users to another site’s
resources using X.25 or Frame Relay.
Key Features
Connect up to eight
async RS-232 devices
to a high-speed X.25 or
Frame Relay line.
Sync interface can be
RS-232, RS-530, V.35,
V.36 (RS-449), or X.21.
Power can be 115 VAC,
230 VAC, or DC.
Through X.28 or SLIP
style menu system,
supports PVCs, call ID,
aliasing, IP routing,
X.32, SNMP, X.25
multicasting, and more.
Flash-upgradable and
rackmountable.

f you have X.25 or Frame Relay
service, why not make the most
of it? Use our X.25 PAD-8 to
weave the data from as many as
eight asynchronous devices into a
single stream for transmission on
a high-speed sync channel!
The X.25 PAD-8’s async ports
are RS-232, pinned out on RJ-45.
Configure each of them for a data
rate from 75 bps to 115.2 kbps.
It’s very easy to run modular
twisted-pair cable from these ports
to any of your async RS-232
devices: PCs, terminals, serial
printers, even bridges and routers.
We offer several types of modular
adapters that you can use to attach
the cable to any of these devices.
Different models of the X.25
PAD-8 come with different syncport interfaces: RS-232, RS-530,
V.35, V.36 (RS-449), or X.21.
Order a model that will work with
your WAN-access device, be it a
sync modem, CSU/DSU, FRAD, or
I
whatever else. The sync port can
handle data rates as high as
2 Mbps.
Not only do you have a variety
of sync interfaces to choose from,
there are also models available for
different power sources. Most of
the sync interfaces are available in
either 115 VAC or 230 VAC
models, and RS-232 and V.35 are
available in DC models as well.
(The DC models can accept –48,
–24, +24, or +48 VDC; they come
with a mating connector that you
can splice onto the end of your DC
power cord.)
You can control the X.25
PAD-8 through a sophisticated
terminal-based menu system. (It
has extended X.28/X.29 or SLIP
command modes and performs
extended X.3 terminal handling.)
First use it to configure the async
channels, setting profiles, sync
link, and system parameters. Then
bring any of these powerful
features of the X.25 PAD-8 into
play for use in your system:
• Permanent virtual circuits
(PVCs).
• Call IDs.
• NUI databases.
• Aliasing.
• IP routing and routing tables.
• Frame Relay funneling.
• X.32 (XID) tables.
• SNMP management and
event reporting.
• X.25 multicasting.
The X.25 PAD-8 has flash
memory, so you can keep
upgrading it—with even more
features—for as long as we keep
releasing new firmware revisions.
If you want to rackmount the
PAD-8, we offer a universal
rackmount kit (RM516) that you
can different pieces from to either
mount a single unit in a 19" rack or
mount two units side by side.
