GL announces UMTS IuCS interface emulation over ATM

April 21, 2014. GL Communications Inc. has announced its enhanced MAPS UMTS IuCS Interface Emulation over ATM.

Karthik Ramalingam, senior manager for product development at GL, said, “Universal Mobile Telecommunications System (UMTS) is a 3rd-generation mobile technology that can support greater data rates for voice,  video, and data transmission to  mobile users. The underlying transport layer for UMTS can be Asynchronous Transfer Mode (ATM) or Internet Protocol (IP).”

GL's LightSpeed1000 hardware platform with quad optical ports, he said, supports simulation of the UMTS IuCS interface over ATM layer using MAPS UMTS IuCS ATM software. The platform supports wire-speed processing on  OC-3/12 and STM-1/4  for functions such as recording, playback, protocol simulation, and analysis of unchannelized ATM and PoS (Packet over SONET). The hardware can also be configured/programmed for delaying of ATM Cells or PPP packets.

He added, “MAPS UMTS IuCS ATM can emulate the RNC (Radio Network Controller) and the MSC (Mobile Switching Centre) nodes by generating RANAP, ALCAP, and DTAP signaling messages over SSCOP. It includes ready-scripts to simulate all IuCS signalling procedures such as Location Update, Call Control MO (Mobile Originating), Mobile Terminating (MT) and SMS procedures.

“The application gives the users the unlimited ability to edit messages and control scenarios (message sequence). “Message sequences” are generated through scripts. “Messages” are created using message templates.”

Ramalingam further added, “MAPS IuCS ATM uses SSCOP server for establishing SSCOP links over which RANAP and ALCAP signaling will be carried for making calls. SSCOP Server is a GL's WCS based server module that provides SSCOP, AAL5 and AAL2 layer services.

“MAPS IuCS ATM internally uses AAL2 Traffic Generator for traffic generation on a successfully established call. Various traffic types like Tone, Digits, and File playback are supported.”
