The sound of key clicks can be turned on or off. The pitch and volume of key

Wiring
The M2250 attendant console requires a 16-pair cable terminated on an
Amphenol connector.
When zone cabling and conduit are used, assign a block of numbers or letters
to each zone. Allow for growth when assigning blocks of numbers.
Cable markers are normally an adhesive-backed cloth tape 1/2 inches wide by
3-1/2 inches long (15 mm by 65 mm) with preprinted numbers.
For limits and cabling for analog (500/2500-type) telephones, refer to
Figure 12 on page 58.
For a list of terminal connections, see Table 5 on page 59.
