Emulation and Verification of Communication Protocols

Gaithersburg, Maryland, USA – September 12, 2013- GL Communications Inc. announced today its single platform software solution for Emulation and Verification of Communication Protocols.

Speaking to reporters, Mr. Karthik Ramalingam, Senior Manager for Product Development of the Company said, “GL's Message Automation & Protocol Simulation (MAPS™) is a protocol emulation and conformance test tool that supports a variety of protocols and it also supports all types of traffic simulation – Voice, Digits, Tones, Fax, SMS, Email, HTTP, and Mobile data traffic.

The product MAPS™ includes various ready-to-use test cases that support the testing of real-time entities. Along with automation capability, the application gives users the unlimited ability to edit messages and control call scenarios (message sequences) and "call scenarios" are generated through scripts.”

He added, “GL's Message Automation & Protocol Simulation (MAPS™) being a single framework – single platform solution that significantly reduces user efforts to simulate multiple protocols / interfaces and it is a PC based solution which makes testing across any network easy and feasible. The user can also perform end-to-end QoS and call control testing from TDM-to-TDM, TDM-IP–TDM, or an All-IP network.

MAPS™ also supports testing inter-working of legacy networks (such as CAS, SS7 and ISDN) with IP networks (such as SIP, MGCP, MEGACO, SIGTRAN) including UMTS, LTE, better known as 3G, and 4G respectively. With customizable protocol messages user can modify any message, message parameters, and/or information elements. Also the user can add, modify or remove any optional parameter depending on specific feature of interest and perform packet level fault insertion by impairing any bit / byte of a message.

The MAPS™ also includes ready-to-run scripts for simulating important call scenarios / procedures and its syntax-ready commands in script reduces dependency on technically skilled resources and in turn that helps in reusability, maintainability and reduced ‘time-to-market’ .”

Mr. Ramalingam further added, “Multiple Link & Transport Layer Simulation capability of the
MAPS™ platform supports multiple transports for IP network (TCP, UDP and SCTP) and supports both IPv4 and Ipv6 and simulates multiple SS7 (MTP) links, LAPD Links. And it is also a useful tool to test and measure the capability of an entity for various traffic conditions.

The test automation feature of the MAPS™ helps define multiple auto-handlers to an incoming message, automate the execution of the multiple calls sequentially or randomly and handle the incoming messages. With its Command Line Interface for Remote Call Control capability, user can send commands from scripting tools such as the TCL, Python and others and can control and operate remotely and gather statistics, logs and reports.

Traffic Simulation feature of the MAPS™ platform supports generation and verification of various traffic types - Digits, Tones, Voice, Fax, and over TDM, Wireless, and Packet networks. It also supports generation and verification of data traffic such as SMS, Email, FTP, Web (HTTP), Video over GPRS, UMTS and LTE. And helps in establishing a voice session, monitor power level, signaling bits, or perform loopback testing real-time voice traffic.  The platform supports almost all industry standard codecs - G711-ULaw, G711-ALaw, AMR, G.726 with VAD, SMV, ISAC, ILBC, and SPEEX.
