MAPS™ APS
(Analog Phone Simulator)

MAPS™ APS is a high capacity Analog 2-Wire FXO/FXS or 4-Wire E&M Bulk Call Generator that performs test on Central Office, PBX, Telephone Adapter, Gateway or other telecommunications equipment. It includes server hardware, GL MAPS™ software, channel bank(s), along with optional modules (Fax Emulation and Voice Quality Testing Analysis) in a compact rackmount system. MAPS™ APS system supports up to 96 independent FXO ports or FXS ports per 1U MAPS™ APS/ALS Server. 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™ APS supports Supplementary Service Testing and Interactive Voice Response (IVR) testing that recognizes and responds to voice prompts using DTMF digits or voice, allowing automated IVR traversal and testing. Provides high-density connection to any 2-wire analog interface for fully automated custom testing.

MAPS™ platform offers automated, scripted, multi-user, multi-protocol, and high capacity Bulk Call Generation. This platform is the basis for all signaling protocols and for 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.

What is the MAPS™ APS used for?

The MAPS™ APS is a high-capacity analog call generator used to test telecommunications equipment such as Central Offices (CO), PBX systems, gateways, ATAs, OLT/ONT, and GPON networks. It simulates bulk analog (FXO/FXS) or 4-wire E&M calls for automated functional, regression, and performance testing.

How many analog ports can the MAPS™ APS support?

The system supports up to 384 analog ports. A single 1U server can handle up to 96 ports, and larger configurations with dual Octal T1/E1 cards scale to 192–384 ports using multiple channel banks.

What types of signaling does MAPS™ APS support?

It supports:

• 2-wire analog: FXO and FXS signaling
• 4-wire E&M: Types I, II, III, IV, and V with immediate start, wink start, and delay dial supervision
• Supplementary services: Caller ID, call waiting, forwarding, conferencing, VMWI

Can MAPS™ APS perform IVR (Interactive Voice Response) testing?

Yes. Using GL’s Speech Transcription Server, MAPS™ APS can recognize voice prompts and respond via DTMF or voice, enabling fully automated IVR traversal and validation.

Does it support fax testing?

Yes. With the optional Fax Emulation module, MAPS™ APS can send and receive faxes, making it suitable for testing fax over analog lines in legacy and VoIP environments.

Is the system automated and scriptable?

Yes. MAPS™ APS offers Python and Java APIs and a Command Line Interface (CLI) for full automation. It integrates with external test frameworks and supports custom scripts for call flows and feature testing.

Can I simulate both subscriber (FXO) and central office (FXS) roles?

Yes. The system can act as:

• FXO (subscriber): Simulating phones calling into a CO or PBX
• FXS (central office): Providing dial tone and ringing to devices like ATAs or fax machines

What kind of reporting does MAPS™ APS provide?

It generates detailed reports including:

• Pass/fail status
• Call success/failure events
• Voice Quality Test (VQT) scores (MOS, PESQ, POLQA)
• Delay measurements (post-dial, one-way)
• Root cause analysis of failures
• Exportable in PDF and CSV formats

Is voice quality testing available?

Yes, Voice Quality Testing (VQT) is an optional feature that provides:

• MOS scoring via PESQ, POLQA, and E-Model
• Voiceband measurements (SNR, gain slope, distortion, noise)
• Ideal for compliance and performance benchmarking

How does the system connect to the device under test?

The MAPS™ APS server connects via T1/E1 digital links to APSCB channel banks (e.g., APSCB-24, -48, -96), which convert digital signals to analog 2-wire or 4-wire E&M interfaces. These connect to patch panels or breakout boxes for physical access to individual ports.

Can I test E&M signaling with wink start or delay dial?

Yes. MAPS™ APS supports all three E&M dial supervision methods:

• Immediate Start
• Wink Start
• Delay Dial

These can be configured through E&M profiles in the software.

What hardware is included in a typical MAPS™ APS setup?

A standard configuration includes:

• 1U or 2U rackmount Xeon server running MAPS™ software
• Quad or Octal T1/E1 card
• APSCB series channel bank (24 to 96 ports)
• Optional VQT server and fax modules
• Cables and breakout boxes as needed

Can multiple users access the system simultaneously?

Yes. The TCP/IP-based client/server architecture allows multiple users and concurrent tests, making it ideal for shared lab environments and team-based testing.

Does it support international telephony standards?

Yes. The system supports programmable call progress tones (dial, ringback, busy) and signaling for various countries and regions, ensuring global compatibility.
