Ringing
The 6416D+ and 6416D+M telephones have electronic tone ringing with eight
possible ringing patterns which you can select by pressing the CONF button while
on-hook. The loudness of the tone ringer can be controlled by the VOLUME
“arrow” button. (The user must NOT be on a speakerphone call. If the user is
using the speakerphone, the VOLUME “arrow” button controls the volume of the
speakerphone.)
Mounting Options
The 6416D+ and 6416D+M telephones come equipped with a nonadjustable desk
stand. The user of the 6416D+ can reverse the stand and then mount the
telephone on the wall.
However, if there is a module connected in the Modular 6416D+M telephone’s
desktop stand, the telephone can ONLY be desk mounted: it CANNOT be
wall-mounted.
Color Options
The 6416D+ and 6416D+M telephones are available in gray and in white.
Wiring Information
The 6416D+ and 6416D+M telephones work in a 2-wire DCP configuration ONLY.
The table below describes the pins on a 6400-Series telephone LINE jack.
Notes on 6400 Series 2-Wire Installation and Wiring:
ALL wiring between the PBX and the telephone wall jack MUST consist of
twisted-pairs. The line cord must be either a D8W, which consists of 4
twisted-pairs, or a D2R which is a 2-conductor non-twisted pair cord. Only these
cord types have been approved by Lucent Technologies. For optimum
performance, the line cord length should not extend beyond that originally
supplied with the telephone.
