To install or troubleshoot a Frame Relay link, you need to test for many things:
physical errors, equipment interoperability, Frame Relay congestion, and even
LAN traffic problems. The Advisor offers integrated Frame Relay protocol
analysis capabilities, along with Bit Error Rate Testing (BERT), stimulus/
response measurements, and statistical analysis capability - everything you
require to get a good look at the physical layer, Frame Relay Signaling, and all
the protocol layers above.
No matter what the traffic level, the Advisor will capture every frame on your
full-duplex network connections. It monitors non-intrusively and captures
Frame Relay data at full line rate. In addition, it can simulate either direction of
a line under test and process previously captured data from its capture buffers
or from a file for retransmission. The analyzer doesnt just capture traffic when
the network is working - it gives you information when the network is broken -
when you need it the most.
The Advisor with its extensive Frame Relay testing capabilities allows you to
test:

There are two acquisition systems for ATM and WAN: the J2300D Advisor
mainframe and the J2900A High Speed undercradle.

The J2300D mainframe comprises the acquisition system for all ATM and WAN
plug-in modules plus the V series interfaces, connectors for which are located
on the body of the mainframe.
In addition, the mainframe includes a full PC running the Microsoft®
Windows98® operating system on a 300 MHz processor, a built in keyboard
with pointing device, a Super VGA active color display, dual PCMCIA card slots,
stereo speakers and the usual printer and serial ports. The PC is used to
control the mainframe acquisition system and the acquisition system in any
attached undercradle, and to collect and post process results.
Note that the PC is not used for real-time processing of measurements this is
all done in the acquisition system and plug-in modules. This allows the PC to
handle multiple tasks such as the Dual Simultaneous Analysis feature which
involves the simultaneous control of the mainframe acquisition system and
attached undercradles, as discussed later.

The J2900A undercradle is similar in function to the J2300D mainframe except
that it has no built in PC but relies upon the PC contained in the J2300D ATM/
WAN or J3446D LAN mainframes to control it and to collect and post process
results. It accepts all ATM and WAN plug-in modules.
