AT&T System 25 - Manual (Page 112)

INSTALLATION
INSTALL TERMINALS
When installing terminals at workstations, consult the Voice and Data Station
Records Form to make sure that you are connecting the right terminal type at
each workstation.
In a replacement installation, single-line and MET voice terminals already in
place may not need to be replaced, although the MET labels change.
Installation is required only for new terminals ordered. Standard MET sets
(2990 Series) require a ZD8AJ-87 (grey) or ZD8AJ-50 (beige) adapter cord
between the modular cord and the wall jack. The 12-button MET set does
not need the ZD8AJ-87 adapter cord. (Only 10-button and 12-button MET
sets may be used with System 25. Also, the set with busy lamp field will not
work unless modified.)
