The Nortel NT7B75AAAE Norstar 4x0 Caller ID Card is a legacy trunk interface module that allows companies to show incoming caller information on compatible digital sets by adding four analog CO lines with complete Caller ID (CLID) capabilities to Nortel Norstar phone systems. This reconditioned 4-port Caller ID trunk cartridge provides LS/DS connectivity for conventional analog lines from telecom companies providing CMS/CLASS Caller ID service. It inserts into open slots on Modular ICS (MICS), Compact ICS (CICS) and similar trunk modules. The NT7B75AAAE translates Bellcore/F SKS formats for easy integration with M7100, M7208, T-series and Meridian displays, making it ideal for small offices, medical clinics and retail establishments that still use dependable Norstar systems. This Norstar 4x0 Caller ID card maintains cost-effective operations for legacy deployments by providing necessary call screening without requiring the upgrade of whole PBXs, due to its universal compatibility across NT7B75 series versions (AA to AAAJ).
