Figure 14-9. The 2554 MMGM and 2554 YMGM Wall-Model Telephones
Like earlier 2500 Series telephones, the 2500 MMGL, 2500 YMGL, 2500 MMGM,
and 2500 YMGM desk model telephones, and the 2554 MMGM and 2554 YMGM
wall model telephones are single appearance analog telephones with
conventional touch-tone dialing. The 2500 MMGL, 2500 MMGM, and
2554 MMGM telephones have NO feature buttons. The 2500 YMGL,
2500 YMGM, and 2554 YMGM telephones are equipped with a FLASH button, a
Message Waiting light, a REDIAL button, a HOLD button, and a MUTE button. All
six of these telephone models provide access to features through the use of the *
or # dial pad keys and the appropriate feature access codes.
On all of these telephones, the user can select either Touch-Tone or Pulse dialing,
whichever is appropriate. There is also a 2-position Positive Disconnect Switch
which ensures faster, cleaner termination of calls when the user presses the
switchhook.
NOTE:
All other 2500 telephones previously available will be manufacture
discontinued beginning in June, 1994. The 2500 MMGL and 2500 YMGL will
be discontinued as of June, 1996, and the 2500 MMGM and 2500 YMGM,
which took their place, will, in turn, be discontinued in December, 1999.
