Tutorials:
Read our helpful tutorials. We have compiled some useful information on various
technologies, their workings, and their place in the industry.
Diameter Reference Guide:
This
Diameter Reference Guide has been compiled by Ulticom to provide an easy
resource for system and service providers as they build out their IMS-based services
and infrastructures.
Session Initiated Protocol (SIP) and the SIP Center:
The SIP Center is a portal for the commercial development of the Session Initiation
Protocol. Serving both the SIP community and the wider industry, the SIP Center
offers comprehensive technical and market resources as well as an environment for
the testing of SIP implementations.

Signaling Summary:
Signaling is a vital communications component that provides telephone companies
with the ability to connect calls and offer services like caller ID, prepaid calling
cards and mobile roaming. While there are many critical factors to consider when
selecting a signaling solution, signaling performance is one of the most important.
Signaling performance
is a general measure of the system's capacity to handle large volumes of messages.
Basic SS7 protocols determine
the ability to deploy applications worldwide. Many support additional higher-level
protocols such as TIA/EIA-41,
GSM MAP,
CAP, BSSAP,
AIN and INAP. Compliance
to standards determines the general applicability of the protocol. Strict compliance
to the very latest standard revision is seldom possible. Compliance tables are used
to precisely define a protocol capability for a given release.
Evolution to SS7 over IP:
Currently the industry is focused on the efforts of the
IETF SIGTRAN Working Group that addresses switched circuit network (SCN)
signaling, with an emphasis on SS7 over IP.
