MLX-5 and MLX-5D Telephones 0
MLX-5™ nondisplay and MLX-5D™ display telephones are compatible with all
system releases. The display telephone includes a 2-line by 24-character display,
and both telephones come with 5 line buttons. In systems prior to Release 5.0, the
MLX-5 and MLX-5D telephones are treated as MLX-10 and MLX-10D telephones
respectively. As of Release 5.0, the system recognizes the MLX-5 and MLX-5D
telephones as 5-button telephones.
If these telephones are connected to communications system releases prior to 5.0
they are recognized by the communications system as 10-button telephones.
