NOTES:
1. All grounds (AG, BG) must be applied before V
B
+ or V
B
-. Failure to do so may result in premature failure of the part. If a user wishes to
run separate grounds off a line card, the AG must be applied first.
2. Application shows Ring Injected Ringing, a Balanced or Tip injected configuration may be used.
