INT-9128R-SW
Non-Blocking Matrix Switch Family
Overview
The INT-9128R-SW is a very large-scale digital matrix
switch family of products for signals with rates ranging from DC to 667
Mbps, and with a total switching fabric bandwidth of over 170 Gbps. Its totally non-blocking and fully buffered switch architecture permits the user to arbitrarily
connect any input to any one or more outputs. Family members include
models with 16, 32, 64 and 128 inputs and outputs. This
combination of large-scale switching and high bandwidth coupled with the
wide variety of signal types described below make the INT-9128R-SW family ideal
for telecommunications, telemetry, ATE, laboratory, military and industrial
applications. Its large-scale, modularity, and versatility enhance the
user's ability to "future-proof" designs of today for tomorrow's
requirements. Furthermore, switches beyond 128 x 128 may be configured
using multiple INT-9128-SW units.
The family accommodates all synchronous, asynchronous
or burst data and clock formats, making possible the switching of
virtually any type of bit serial data stream from DC to 667 Mbps. Signals
may be paired together to accommodate NRZ data and clock, or may be
switched independently for signals with embedded timing (T1/E1, T3/E3,
asynchronous, etc.). Also multiple signals may be grouped together to
permit switching of parallel busses such as the OpenLDI LVDS flat
panel display interface.
Customized rear connector panels are routinely
fabricated to individual customer requirements to simplify installation
and cabling and to achieve direct plug to plug compatibility with customer
equipments. These may be either signal based, where there are separate
sets of input only and output only connectors, or port based, where each
connector has both input and output signals and are switched as a full
duplex connection.
Internal to the unit each block of 16 connectors is interfaced into the switch matrix by a
plug-in signal converter card. The user may customize a switch for a
specific application by selecting converter cards, connectors and pin
assignments to match their
requirements. RS422, RS423, RS485, RS232, TTL, ECL, PECL, LVDS, LVPECL,
DS1, T1, T3, E1, E3, E4 and STM-1 converter cards are available today, and additional
types are under development. A re-clocking option
is also available for clocked high speed signals to minimize output jitter
and skew.
Control and status is provided via the optional front panel or via a rear panel
9-pin D connector serial port conforming to EIA standard
RS-232C. The operational configuration is maintained in non-volatile
memory at all times and is restored when power is applied. The units are
typically 4U (7") high standard 19" rack mounted enclosure requiring 150 Watts of 120/230 VAC
50/60 Hertz power. The size may vary depending on the customer's choice of
rear panel connectors and configuration.
