2. Minimum return loss for 2048 kbit/s service
3. Limits for maximum peak-to-peak jitter for
     2048 kbit/s service (independent of reflected
     jitter performance requirements)

     intrinsic jitter for 2048 kbit/s service
     (independent of reflected jitter performance
     requirements
5. Minimum return loss for 8448 kbit/s service
6. Limits for maximum peak-to-peak jitter for 8448
     kbit/s service (independent of reflected jitter
     performance requirements)

8. Output jitter requirements clauses: planning
     exemption categories according to service category
     and use as related to declared output signal timing
     as required by 7.1.8
