“MAPS™ (Message Automation and Protocol Simulation) Central Office Switching Simulator converts a PC (portable, tower, rackmount) into a digital central office switch simulator, PBX and switch, complete with T1, E1, POTS, and IP interfaces,” said Vijay Kulkarni, CEO of GL Communications. “MAPS™ Central Office Switching Simulator is ideal for simulating and testing advanced telecom infrastructure including PBX, switches, gateways, and transmission systems. The simulator performs complex switching functions for routing PSTN to TDM calls while providing voice/data throughput and protocol conversion during call switching. MAPS™ can emulate both ends (or one end) of a complex switching network, and the switching equipment itself such as the SS7 SSP for routing TDM calls to/from local PSTN telephone exchange.”

He further added, “All signaling and traffic actions are easily controlled via scripts and provides all the flexibility required from a telephony test equipment. The Central Office Switching Simulator can also be used to verify all PSTN, IP and T1/E1 signaling protocols over different transport within the network infrastructure. These protocols include T1/E1 CAS, PRI ISDN, SS7, and IP protocols. It can also generate traffic such as digits, tones, voice files, fax, and more.”


  • A single-box system to test central office, PBX, gateways, analog/ IP networks
  • Provides complete network infrastructure for PSTN, IP, digital T1/E1 trunks, SS7, ISDN, and POTS (Plain Old Telephone System)
  • Call switching/routing among TDM-PSTN networks with protocol conversion capability
  • Automatic bulk call generation/reception for load testing
  • Automate call establishment and traffic generation / detection process through scripts
