DIAGNOSTIC PROTOCOL & WORKFLOW

Our Four-Phase Engineering Methodology

From high-voltage analog 70V speaker lines to complex SIP-based VoIP multicast paging architectures, we apply methodical acoustic and electrical testing to resolve persistent communication failures.

PHASE 01
SYS_CAPTURE

Remote Telemetry & Acoustic Capture

Direct diagnostic inspection of centralized headend controllers, line-level audio inputs, and zone preamplifiers.

TARGET PROTOCOLSIP / RTP / Line-In
Signal Floor Ratio> 65 dB SNR

Ambient noise mapping, paging microphone gain structure analysis, and zone matrix routing verification across existing hardware.

PHASE 02
IMPEDANCE_TEST

Wiring & Impedance Load Testing

Comprehensive 70V and 25V speaker line impedance testing to prevent amplifier clipping and transformer saturation.

TARGET PROTOCOL70V / 25V Constant Voltage
Line Load Margin20% Headroom Target

T-tap detection, short-to-ground isolation, total transformer wattage load summation, and return-loss verification.

PHASE 03
IP_SIP_AUDIT

IP Network & SIP Endpoint Audit

Packet-level analysis of IP horns, SIP paging adapters, multicast routing, and VoIP PBX registration parameters.

TARGET PROTOCOLG.711 / G.722 Multicast
Jitter Tolerance< 15ms Latency Window

QoS DSCP tagging validation, PoE switch port power budget calculation, and SIP trunk registration handshake telemetry.

PHASE 04
FIELD_DEPLOY

Field Remediation & Zone Commissioning

Concrete step-by-step dispatch documentation, field technician remote guidance, and complete acoustic tuning.

TARGET PROTOCOLBogen / Valcom / Algo / TOA
Speech Transmission Index> 0.62 STI Certified

Zone-by-zone intelligibility testing, volume leveling across high-noise warehouse areas, and final sign-off deliverables.
