Z100B1

FILTER Passes voiceband frequencies up to 4 kHz while providing high-attenuation suppression from 5 kHz to 200 MHz, utilizing an integrated common-mode choke to eliminate radio frequency interference (RFI). | Modular Inline Telephone Line Low-Pass RF Filter Case with RJ11 Jacks at Both Ends | Central office copper trunks, subscriber premises telephone line drops, locations suffering heavy AM radio transmitter or amateur radio signal ingress. | Z100B1 | None | None | AT&T Z100B1-246, Lucent Z100B1, Comcode 106605553, Westek TC-Z100B1 | Telemetry Test Bench RFI Suppressor: Snapped inline ahead of a high-isolation diagnostic test-bench modem setup to strip induced high-frequency motor noise and AM radio cross-talk from the physical incoming subscriber copper pair without degrading base voiceband signal integrity. | AT&T / Lucent Technologies Central Office Network Equipment: This high-reliability telecommunications network filter module was engineered by AT&T to allow concurrent voice and data transmissions over a single shared copper infrastructure pair while cleanly blocking unwanted electromagnetic spike ingress
