GL Communications, Inc. MAPS™ MEGACO Protocol Emulator PKS122

The Media Gateway Control Protocol (MEGACO/H.248) is a signalling and call control protocol used between the Media Gateway Controller (MGC) and Media Gateway (MG) for supporting multimedia stream transmission. The MGC uses Megaco/H.248 to instruct MG about the events, media, signals to be played on Terminations, to create a Context, and to audit the status of the Terminations involved in the conversion of media from one type of network, to the media required in other type of the network. GL’s MAPS™ MEGACO (H.248) Protocol Emulator supports Trunking Gateway and Residential Gateway simulation using binary based H.248 protocol and text based MEGACO protocol in Digital and Analog network respectively. MAPS™ now supports both binary and textual encoding protocol versions. The binary encoding is based on Basic Encoding Rules (BER) description of the protocol and text encoding is based on Augmented Backus-Naur Form (ABNF) description. The MEGACO/H.248 protocol is implemented in binary encoding over 2G/3G core network. However, it can be still used in traditional text based encoding in IP networks as well. It is typically used for providing Voice over Internet Protocol (VoIP) services like voice and fax between different networks – such as IP Networks and the PSTN, IP Networks and Wireless Networks (2G/3G) or entirely within IP Networks. The MAPS™ MEGACO (H.248) also supports Conformance Scripts (requires PKS123 licenses), which includes 200+ test cases as per Megaco specification of ETSI TS 102 374-2 document. Test suite includes in-built scripts which tests the functionality of the Media Gateway for Megaco protocol valid and in-valid behaviour. With the purchase of RTP Core license (PKS102), MAPS™ MEGACO supports transmission and detection of various RTP traffic such as, digits, voice file, single tone, dual tones, IVR, FAX*, and Video*. With regular RTP traffic, the maximum Simultaneous Calls up to 2500, and Calls per Second up to 250 is achievable. Almost all industry standard voice codec supported. GL’s MAPS™ MEGACO is also available in High Density version (requires a special purpose network appliance and PKS109 RTP HD licenses). This is capable of high call intensity (hundreds of calls/sec) and high volume of sustained calls (tens of thousands of simultaneous calls/platform). GL also offers MAPS™ Media Gateway Controller (MGC - PKS300), a multi interface simulator is configured to handle call control between the Signaling Gateway (SG) and Media Gateway (MG) in the network to perform end-to-end test scenario by simulating SIGTRAN, MEGACO and MGCP interfaces. GL recommends purchasing additional MG simulation with appropriate RTP licenses for high density traffic simulation. ** Some of these traffic types requires additional licenses – contact GL for more information
