Panduit VP25344KBLY 25-Port Category 3 ISDN/Telephone Flat Patch Panel

The Panduit VP25344KBLY delivers 25 Cat 3 termination points in a compact 1U format for legacy ISDN and analog telephone systems. Built on cold-rolled steel, this Pan-Net® voice patch panel provides reliable cross-connect infrastructure for PBX, key system, and POTS deployments where twisted-pair voice circuits need organized, labeled termination separate from data network patch fields.

Key Features

25 Cat 3 ports in 1U—high-density voice termination for small to mid-size telephone systems

Cold-rolled steel construction withstands repeated patch cord stress in production telecom environments

TIA/EIA-606-A compliant labeling areas simplify circuit identification and MAC work

Black finish integrates with voice/PBX equipment racks and separates visually from data patch panels

EIA environmental and electrical performance standards ensure consistent operation in HVAC-controlled telecom rooms

CE and RoHS compliance meets European and environmental regulatory requirements for global deployments

Category 3 patch panels remain the go-to termination platform for analog voice and ISDN BRI circuits that don't require Cat 5e or Cat 6 performance. The VP25344KBLY's 25-port density fits small office PBX installations, building entry point cross-connects, and legacy telecom equipment integration projects where copper POTS lines or PRIs need physical layer organization. Cold-rolled steel provides rigidity under load—critical when patch cords are inserted and removed weekly during MAC operations or troubleshooting. The flat panel format presents all ports in a single horizontal row, eliminating the staggered or angled layouts that complicate cable management in tight rack spaces.

TIA/EIA-606-A compliance ensures the panel ships with standardized label fields for circuit IDs, enabling integrators to document trunk groups, station extensions, and tie lines in a format that survives turnover and after-hours emergency dispatch. Black powder coat finish differentiates voice infrastructure from data network equipment in converged telecom rooms where multiple patch fields coexist. The Pan-Net® design lineage shares mounting and management compatibility with Panduit's copper infrastructure ecosystem, allowing voice and data to occupy the same 19-inch racks with consistent aesthetics and tooling.

Meets TIA/EIA-606-A labeling standards, EIA environmental and electrical performance specifications, CE marking, and RoHS material restrictions. Ideal for PBX interface installations, ISDN BRI aggregation, analog trunk termination, and retrofit projects where existing Cat 3 horizontal cabling remains in place. Panduit's manufacturing ensures consistent build quality across production lots—a requirement when you're stocking spare panels for phased rollouts or future expansion bays.
