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

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.
