Overview
Developers of telephony products intended to connect
with telephony circuits prefer access to the "real
thing.” But gaining access to the “real thing” is an
expensive and aggravating proposition. So, usually you
just guess. Why guess? With Gordon Kapes Inc.'s System
930 Telephony Simulator now you can know.
The System 930 is essentially a digital telephone
network in a box.The System 930's robust features
include:
•
Your choice of ISDN PRI protocol, Robbed Bit T1
protocol, or both. Two 1.544 Mbps digital interfaces
permit an “end-to-end” simulation of a PSTN/VPN. This
means you can simulate telephone calls transmitting
across a digital telephone network, testing candidate
application(s) connected at either end.
•
The
System 930 can emulate the network or user side of T1 or NI-2 compliant
ISDN PRI. 4ESS, 5ESS, DMS100/250, and GTD5 switches can be emulated. The
System 930’s software facilities accommodate Q.931 public or private
networking protocols. Private or proprietary networking protocols that
employ out-of-band progress tones can be accommodated.
•
Called
number information, or DTMF DNIS, is employed to route incoming digital
call traffic to the other digital interface, or to convert and route
calls to analog, loop-start telephone ports (either individually or to
ACD-like port groups). Eight analog telephone ports are provided as
standard equipment in each System 930. Additional telephone ports, to a
maximum of 32, are optional. Alternatively, incoming calls can be
connected to the system’s two integrated solid-state announcers. Voice
messages up to 20 seconds in length can be recorded and stored for
future playback.
•
The
System 930’s protocol analyzer displays ISDN messages sent to or
received from either digital interface. Layer 1, 2, and 3 information is
displayed. Robbed Bit T1 protocol-equipped System 930s display A-B bit
status and DNIS DTMF digits received.
•
The
System 930’s internal “bulk” call generator can be programmed to
initiate up to 23 or 24 simultaneous calls per interface on a repetitive
basis. Call generator scripts can be created to approximate “real-world”
events. For example, the call generator can be scripted to wait for the
called party to answer, then send DTMF or progress tones, play stored
messages, and execute variably timed disconnects. Intuitive codes used
in scripting allow quick and easy setup.
•
An audio
output jack allows use of amplified external speakers to monitor calls.
•
A
personal computer or terminal emulating VT100 is used to program the
System 930 and access its status displays. ASCII-format data can be
exchanged between the System 930 and a remote terminal. Eight test
profiles can be stored within the System 930.
•
The
System 930’s simple, menu-driven programming and extensive on-line
documentation make it easy to use.
•
The
System 930 comes completely provisioned for use as soon as it is
unpacked and set up. Each System 930 comes with a precision 48 Vdc power
supply, a set of amplified audio speakers, and an assortment of jacks,
cables, and patch cords. An optional hard-shell travel case is
available. The System 930 weighs slightly less than 30 pounds and
measures approximately 14-inches high x 12-inches wide x 10-inches deep.
•
Warranty: 3 years on hardware, 1 year on software.
