A Telephony Softswitch solution from Ericsson provides full PSTN compatibility with 99.999 percent availability – over IP infrastructure.

It provides:

• Cost-efficient modernization of national and international transit (Class 3&4) as well as local (Class 5) telephony networks
• Interconnectbetween voice-over-IP networks (both SIP and H.323) and H.248-based TISPAN access gateway control
• A safe evolution path from TDM to all-IPSignificant opex and total-cost-of-ownership savings.

Ericsson has more than 80 Telephony Softswitch customers globally. A majority of the customer networks are in commercial service.

Telephony Softswitch offers an efficient and cost-effective migration path for operators wanting to modernize their networks for narrowband telephony or provide broadband and multimedia services over IMS.

This is achieved by reusing existing softswitch components – important building blocks for the evolution into an all-IP network – ensuring operators can reuse their existing investments.

Ericsson’s extensive integration competence and network transformation experience with large-scale networks make it the perfect partner for operators engaging in this transformation from TDM to IP.

Operator case studies and experience from live networks show that softswitching can significantly cut costs:

• Overall core network opex can be slashed by up to 50 percent
• Total cost of ownership can be reduced by up to 20 percent
• Operations and maintenance costs are lowered.
