9 3COM LEGACY LINK CARDS The 3Com Legacy Link Cards enable you to use existing Meridian, Norstar, or analog telephones with an NBX system. Each card supports up to 16 handsets using the existing telephone wiring, punchdown blocks, and connectors. 3Com offers these Legacy Link Cards ■ 3Com Legacy Link Analog Card ■ 3Com Legacy Link Meridian Card ■ 3Com Legacy Link Norstar Card 3Com Legacy Link Cards are not compatible with an NBX system that has been SIP-enabled. 3Com Legacy Link Analog Card The 3Com Legacy Link Analog Card fits into an available slot in an NBX chassis. It translates the analog handset protocol to a format suitable for use with an NBX system. The telephone features available through a connected analog handset are as described in the NBX Feature Codes Guide for Analog Handsets subject to the analog phone capability. For example, paging requires an on-hook speaker capability that might not be available on an analog phone. No additional power is required for the phones. The analog phones are line powered from the 3Com Legacy Link Analog Card.
