Figure 14-11. The 2554 MMGN and 2554 YMGP Wall-Model Telephones
The newest 2500 telephones are the 2500 MMGN and 2500 YMGP desk model
telephones, and the 2554 MMGN and 2554 YMGP wall model telephones. These
models will take the place of the 2500 MMGM, 2500 YMGM, 2554 MMGM, and
2554 YMGM, which will be discontinued as of December 31, 1999.
Like the original 2500 sets, these new 2500 telephones are single appearance
analog telephones with conventional touch-tone dialing.The 2500 MMGN and
2554 MMGN telephones have NO feature buttons. The 2500 YMGP and 2554
YMGP 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.
These 2500 Series telephones are automatically set for touch-tone dialing. The
Positive Disconnect feature, which ensures faster, cleaner termination of calls
when the user presses the switchhook, is also set at the factory.
