M2250 2 Prong Adapter
A Nortel M2250 2 Prong Adaptor (NTAG95AA) is needed to connect handsets or headsets to a M2250 or PCCIU console. Nortel consoles are compatible with either carbon or electret mics, adjusting audio levels automatically. Note that electret mics are
polarity sensitive: the brandline (NT) plate on the 2 prong handset adapter must face down on a 2250, and forward on the PCCIU.
The 2 prong adapter is two 6.3mm mono jacks, and entirely passive:
| Jack | Tip | Sleeve |
|---|---|---|
| Top → | Yellow | Red |
| Bottom → | Black | Green |
- Tips (black/yellow) are the mic
- Rings (green/red) are the earpiece
- Jacks go to M2250, cable to handset
