PALM's SS7-IP Signaling Gateway (SS7IPGW) is a
software product that handles all SS7 ISUP signaling and exports
a simple interface to call control applications. The SS7IPGW can
be purchased as a binary process that runs along side your
applicatoins in the same processor as a COM service, or can be
run as a separate, black box, attached to your LAN. PALM will
provide additional consulting services to fully integrate this
product into you application suite and OSS by interfacing to
your OAM&P system. Use your own Media Gateway or one
provided by PALM to act as a presentation level content manager
that changes incoming circuits to IP traffic streams or
interfaces the telephone network to your switching system.
A simplfied call control interface is available whether the
SS7IPGW operates in its own system, providing a separate "SS7 in
a box" solution or as a peer process within the same system as
the call control application. Call control applications that are
co-located with the Gateway can use the convenient COM
interface. Remote call control applications can access the
Gateway using DCOM or IP. For IP, the RCCP is available (Remote
Call Control Protocol ®) developed by PALM Associates, Inc. RCCP
can operate over TCP, UDP or Secure/Reliable UDP protocol
Future releases of this product will include TCAP support as
well. Additional features include remote administration and
monitoring, local control panel, Remote/Local provisioning,
power/fail restart, and dual system fail over.
Call Control Application Interfaces
A variety of interfaces are possible for applications program
developers. When the Gateway is collocated with the
application, a COM interface is possible. For situations where
the call control application is external then the RCCP©
Protocol over TCP or UDP is used, or alternatively DCOM is
By combining the SS7 Signaling Gateway with a Media Gateway, a
full IP Telephony solution can be built or an Intelligent
Peripheral such as a Fax Server or IVR application can be
attached to a switch.
The optional fault tolerant, distributed implementation using
the ForemanÔ Management Framework, console and agents, can
provide high performance management.
For Dialogic platforms, CT Media can be used to manage the
media streaming through the Media Gateway.
This product is intended primarily for small to medium size
installations or to be used for developing applications for
enterprise level services.
