Portable
Networking Protocol Analyzers and
Datacom BERT Family
Our Network
Testing Equipment includes a variety of portable
testing equipment for networking professionals.
Our HCT Series testers are menu
driven protocol analyzers with industry standard
interfaces such as V.35, X.21, RS-530/449/232,
sync or async. They provide protocol analysis
of ASYNC, SYNC(BSC), HDLC, SDLC, X.25, DDCMP,
Frame Relay, SNA, PPP, SLIP, V5.1, V5.2, ISDN-D
and SS7 as well as BERT (Bit Error Rate Testing)
functions.
Our Datacom BERT testers (HCT-BERT)
are menu driven data communication testers similar
to our HCT Series but with BERT
functions only. They provide a wide range of testing
patterns and operate as a pattern generator and/or
receiver. |

The
HCT Series of notebook sized communications
testers are communication protocol and/or BERT
(Bit Error Rate Test) analyzers that provide a
wide range of protocol communications, suitable
for equipment installations, on-line or off-line
diagnostics, debugging, and interface development.
All HCT Series feature backlit Liquid
Crystal Displays, tactile membrane switch keyboards,
interface lead indicator LEDs, and internal rechargeable
batteries. Included with the HCT-7000 or
HCT-6000 is a CDROM with both DOS and
Windows based monitor programs, a comprehensive
User's Guide, universal AC power adapter (100
to 240VAC), and a sturdy zippered carvas carry
case. A full assortment of interface adapter cables
and adapters are available for a wide range of
interface standards.

| HCT Series of Protocol / BERT Analyzers
|
| The
HCT-7000, flagship
model of the HCT Series, provides WAN protocol
analysis for ASYNC, SYNC (BSC), HDLC, SDLC, X.25,
SNA, DDCMP, TCP/IP, PPP, SLIP and Frame Relay
communications at full E1 transmission speeds
(2.048Mbps), plus 2M (2.048Mbps) BERT (Bit Error
Rate Testing). The basic unit supports two hardware
interface modules that can be any pair supporting
RS-232C (V.24/V.28), RS-530, V.35, RS-449 (V.36),
X.21, G.703 E1, G.703 T1(DS1), or G.703/64K Co-directional.
The HCT-6000 model includes protocol analysis for ASYNC, SYNC(BSC), HDLC, SDLC,
X.25, DDCMP, TCP/IP, PPP, SLIP and Frame Relay
communications. The HCT-6000 is
capable of two modes of BERT testing. Low speed
BERT is supported at speeds up to 128Kbps, while
high speed BERT supports speeds at up to 2.048Mbps.
The hardware interfaces supported include RS-232C,
V.35, X.21, and RS-449.
The
HCT-6000A model includes
all the features of the HCT-6000
with the exception of high speed (2M) BERT.
The HCT-BERT/2M model provides 2M (E1 and
T1 speed) and 128K BERT only, without any protocol
analysis.
The HCT-BERT/128 model provides only 128K
BERT capability without any protocol analysis.
The HCT-2000E model includes
protocol analysis for ASYNC, SYNC(BSC), HDLC,
SDLC, and X.25 Frame and Packet plus BERT at
speeds up to 72Kbps. The hardware interfaces
supported include RS-232 (V.24/V.28) and V.35.
