Analog <-> ISUP Call Conversions
The MAPS™ Central Office Switching Simulator can be configured as a high-density switch, which supports large volumes of various traffic including voice, fax, modem, and tones.
Being a self-contained system with capabilities to easily communicate with external networks, the MAPS™ Central Office Switching Simulator can switch calls originating from PSTN network to SS7 and vice versa.
As depicted in the test setup, MAPS™ CO application is configured on a PC with T1 E1 boards, which is connected between PSTN and SS7 networks to switch analog calls to SS7 and vice-versa.
On the PSTN side, the FXS interface of the channel bank is connected to the FXO Analog phones via breakout box. The T1 E1 ports on the channel bank are connected to GL's T1 E1 Analyzer board (OctalXpress E1), where MAPS™ CO simulator is installed and running. On the other side, the OctalXpress ports are connected to the SS7 system as shown in the figure.
The following screenshot depicts MAPS™ CO Simulator configured to switch and route incoming SS7 calls to Analog (FXO) terminal. MAPS™ CO receives the called number in the SS7 Initial Address message and uses the Called Party Number to identify the subscriber on the FXO side and routes the call on the associated timeslot/trunk towards FXO.
MAPS™ CO Switching Calls Originating from SS7 to PSTN
The following screenshot depicts MAPS™ CO Simulator configured to switch and route incoming analog calls to SS7 system. Each FXS line is configured with calling number (ANI) and is associated with the timeslot/trunk. When the PSTN call is received, MAPS™ CO forwards the received dialed number to SS7 system and switches the incoming call based on the number dialed (called/calling number).

Overview
MAPS™ Central Office Switching Simulator converts a PC (portable, tower, rack-mount) into a digital central office switch simulator, PBX and Switch, complete with T1, E1, POTS, and IP Interfaces.
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 TDM and PSTN calls, while providing voice/data throughput, and protocol conversion during call switching. MAPS™ CO 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. 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, FXO, FXS, and IP protocols . It can also generate traffic such as, digits, tones, voice file, fax, and more.
The CO Switching Simulator can be controlled remotely using the optional Remote MAPS™, Client/Server applications (CLI), and scripting with which users can capture the performance of networks in a wide variety of scenarios. The Remote Capability allows full control of many COs from a single client as well as many clients accessing a single CO.
