GL Announces High Capacity Analog 2-wire Bulk Call Generator

Welcome to December, 2015 issue of GL's Newsletter providing information and insight into our latest product Analog 2-wire Bulk Call Generator referred to as MAPS™ Analog Phone Simulator (APS).

MAPS™ APS Network Diagram


MAPS™ APS 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. It includes a compact system comprising of MAPS™ APS, Analog Interfaces, Patch Panels and other optional modules (Fax Emulation and VQT Analysis) in a rack mount system.

MAPS™ APS system supports up to 192 channels independent FXO ports per 1U MAPS™ APS Server and APSCB-48 and more can be achieved by simply scaling the system with a 4U MAPS™ APS 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.
