General description
The M522 add-on module can be attached to the M5216 or M5316 Meridian
Business Set to provide extra feature/line keys (see Figure 1-1). When one

(through a non-loaded subscriber loop pair) to the Northern Telecom DMS–
10, DMS–100, DMS–250, or Meridian SL–100 Digital Switching systems.
