Notes:
1. To silence ringer permanently:
(a) For all classes except tip party identification, connect (Y) mounting cord to same terminal as (R) mounting cord
lead at connecting block.
(b) Tip party identification:
• For lOOO!l ground remove (R) from K of network and insulate and store on unused terminal.
• For 2650!l ground remove ( S) from K of network and insulate and store on unused terminal.
2. If bell taps on stations connected to long line equipment, use these connections to retain party ground identification.
3. When grounded ringer arrangements are used with 96 volt long line circuits, a D-180036 ·ringer isolator must be used.
4. See Note 5, Fig. 4.
