GL Announces UMTS IuCS Interface Emulation over ATM

Gaithersburg, Maryland, USA - August 18, 2014 - GL Communications Inc., announced today its enhanced MAPS™ UMTS IuCS Interface Emulation over ATM.  

MAPS™ UMTS IuCS Interface Emulation

Speaking to reporters, Mr. Karthik Ramalingam, Senior Manager for Product Development of the company 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 supports simulation of UMTS IuCS interface over ATM layer using MAPS™ UMTS IuCS ATM software. It 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, PoS.   The hardware can also be easily 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 Center) nodes by generating RANAP, ALCAP, and DTAP signaling messages over SSCOP. It includes ready-scripts to simulate all IuCS signaling 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.”

Mr. 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.”
