Speaking to reporters, Mr.
He added, "GL's MAPS™ (Message Automation and Protocol Simulation) platforms can be used to simulate various elements in a hybrid TDM VoIP network. As depicted in the enclosed network diagram, SS7 signaling in the PSTN is translated to SIGTRAN by the Signaling Gateway (SG). TDM traffic is repackaged into RTP packets by the Media Gateway (MG). A Media Gateway Controller (MGC) controls the various elements within the IP Network using SIP, Megaco, and MGCP protocols. The reverse may happen if the call is destined to PSTN. If the call stays within the IP domain, then an IP PBX may route the call to an IP endpoint.
A typical MAPS™ platform simulating a Signaling Gateway may consist of high density T1 E1 Cards, a Gigabit Ethernet Card, a multiprocessor CPU (such as an i7 PC) and MAPS™ SIGTRAN and MAPS™ SS7 software. Pre-written scripts translate SS7 to Sigtran and vice a versa. Media Gateways can be similarly integrated using MAPS™ software products, for Media Gateways high density T1 E1 Cards and MAPS™ Megaco or MAPS™ MGCP is required. Similarly, MAPS™ can assume the role of any of the elements."
MAPS™ SIGTRAN and MAPS™ SS7 can be combined into one entity to emulate a complete Signaling Gateway. M3UA, M2UA, and M2PA modes are easily supported.
MAPS™ MEGACO or MAPS™ MGCP can be configured with T1 E1 trunks to simulate a Trunking Media Gateway. Megaco signaling to/from a Media Gateway Controller is used to establish TDM to RTP connections and vice versa. Codec support is provided for common G.711 ULAW, G.711 ALAW, G.729, G.729B and many more. Fax is also supported.
MAPS™ MEGACO, MAPS™ SIP, MAPS™ MGCP, and MAPS™ SIGTRAN can be combined to perform Media Gateway Controller functions - interacting with multiple Media Gateways and multiple Signaling Gateways and as a SIP server as well. Scripts can be written to route calls to different
PacketScan™ - an All-IP Analyzer can be configured on a remote system for capturing all-signaling - SIGTRAN, MEGACO, SIP and RTP Traffic in real-time. An SS7 Analyzer can be configured on a remote system for capturing all SS7 signaling and bearer traffic."
Founded in 1986,
GL's test tools range from simple PC-based software test tool to all-encompassing hardware units with futuristic expansion capabilities. GL's test solutions cover wide array of networks – 4G (LTE), 3G, IP, Ethernet, T1, T3, E1, E3, OC-3/STM-1, OC-12/STM-4, and traditional PSTN networks.
GL's tools are widely used by the telecommunication industry for conformance testing, automated stress/load testing, performance testing, remote accessibility, centralized web-based control and analysis, fault testing and analysis, and customized testing.
