Original Press Release

High Capacity Analog 2-wire Bulk Call Generator

Press release date: Aug 01, 2017

Overview

The MAPS™ APS/ALS is a high capacity Analog 2-wire Bulk Call Generator used to test a Central Office (CO), PBXs, ATAs, Gateways or other telecommunications equipment, which provide local loop interfaces. MAPS™ APS system supports up to 192 channels independent FXO ports or FXS ports per 1U MAPS™ APS/ALS system. This compact system comprises of MAPS™ Server, Analog Interfaces, Patch Panels and other optional modules (Fax Emulation and VQT Analysis) in a rack mount system.

More can be achieved by simply scaling the system with a 4U MAPS™ APS/ALS Server sporting 2 Octal T1 E1 Cards which can then support up to 384 analog ports.

MAPS™ platform offers automated, scripted, multi-user, multi-protocol, and high capacity Bulk Call Generation. MAPS™ is the platform for all signaling protocols and traffic generation - whether voice, tones, digits, fax, data, or video, depending on the network support. MAPS™ covers legacy PSTN, TDM, SONET SDH, next generation VoIP, and Wireless protocols, interfaces, and equipment. MAPS™ can support any of the following protocols in TDM networks for establishing the signaling links - CAS, FXO FXS, ISDN, SS7, PPP, GSM, INAP, CAP, and MAP.

Available Platforms

GL’s MAPS™ APS/ALS systems are available in 24-Port, 48-Port, 96-Port, and 192-Port FXO and FXS configurations. Higher capacities can be achieved by simply scaling the system configurations.

GL also provides 24-Port WB FXO Test Solution using 2U HD VQuad™ System, as shown below, which offers support for both narrowband (NB) and wideband (WB) high-definition (HD) audio.
