SPS-4
Multiprotocol Packet Switch
Connects legacy equipment to modern
networks
SPS-4 performs packet switching between
different applications, such as X.25 to X.25;
X.25 to Frame Relay; Frame Relay to Frame
Relay; and SLIP to SLIP. It can also encapsulate
various protocols over Frame Relay and X.25.
The product is ideal for banks, hospitals,
universities, or other organizations with a large
installed base of legacy equipment that needs
to be connected over more modern networks.
Radio backup link for mission-critical
applications
SPS-4’s single RS-232/V.24 asynchronous data
port can support GPRS packet streams so that it
can be utilized as a radio backup link for critical
link applications. Switching to the backup link
occurs automatically upon detection of main link
failure. After the network recovery, the SPS-4
automatically synchronizes itself and returns
transmission to the main facility link.
The synchronous data links on the SPS-4 can be
ordered with V.24/RS-232, V.35, RS-530, X.21,
V.36 interface with DCE or DTE settings, or with
ISDN S or U interface options. This provides
connectivity for any device with a standard
network interface. For added flexibility, the
synchronous links can also be configured for
asynchronous operation.
Management options
The built-in management agent enables
configuration, compilation of statistics and status
reports, and diagnostics. The management agent
can be accessed from any location in the
network. It can be programmed to transmit this
information as the result of an alarm event.
Advanced FCAPS (Fault, Configuration,
Accounting, Performance, Security) and
diagnostic tools are provided by RADview-EMS,
RAD’s carrier-class element management system,
via a Web browser.
The standalone SPS-4 is a compact, 1U-high,
half 19-inch wide unit.

The SPS-4 is a flexible, compact switch, providing
multiprotocol connectivity for transporting data
from X.25 and Frame Relay equipment over newer
xDSL, E1/T1 and IP networks. SPS-4 provides up to
three sync/async links that can be independently
configured to one of several protocols: Frame
Relay, X.25, ISDN, RIP, RIP-2, PPP, MLPPP, HDLC,
SLIP, or async.
