ORLANDO, Fla. Tekelec Inc. and Hewlett-Packard Co. announced a joint development and marketing agreement at Wireless 2007 here in which the partners will combine expertise in blade-based Advanced Telecommunications Computing Architecture (ATCA) servers implementing nodes in IP multimedia subsystems.
Tekelec will apply its talents in signaling from its Eagle line of SS7, NGN and IMS software, which is used in the IMS node called the Call State Control Function. HP will bring its Home Location Registers and Home Subscriber systems expertise from its OpenCall product suite.
Stephen French, senior manager of product marketing for next-generation signaling at Tekelec, said many carriers moving to IMS want to preserve support for SS7 and Next Generation Networks "soft switch" functions. Thus, the unification of all three architectures represents a "unified sandbox" with a common signaling control plane.
ATCA servers offered by Tekelec and HP are based on Linux OS and Intel CPUs, so "Intel is a strong supporter behind the scenes of this effort," French said.
Tekelec is free to work on open ATCA solutions with other vendors, but HP is well ahead of other server developers both in telephony applications and in its use of ATCA.
Tekelec recently shed its switching solutions group, selling the soft switch elements to GenBand Inc. of Dallas for $1 million along with an equity stake in GenBand. GenBand executives had been involved in all three switching companies acquired by Tekelec to create its switching business: Taqua Systems Inc., Santera Inc. and VocalData Inc.
