Description
The Newbridge 90-3553-11/H is a DS3-level CFR (Channel Frame Relay) interface module used in legacy Newbridge telecommunications systems. Modules in the 90-35xx series were part of the MainStreet / Newbridge 3600 / 3630 multi-service platforms for carrier networks, providing digital interface and frame relay connectivity at DS3 (44.736 Mbps) rates. These cards handle CFR traffic aggregation and framing between network transmission equipment and internal switching or transport backplanes in legacy telecom nodes.
