General configuration notes
Service provisioning tasks are typically performed before provisioning a subscriber
            service and can be logically separated into two main functional areas: 
- core tasks
- subscriber tasks
The core tasks must be performed before the subscriber tasks.
Core tasks include the following:
- 
Create customer accounts. 
- 
Create template QoS, filter, scheduler, and accounting policies. 
- 
Create SDPs. 
Subscriber tasks include the following:
- 
Create Cpipe, Epipe, IES, Ipipe, VPLS or VPRN services on the 7750 SR. 
- 
Create Epipe, IES, Ipipe, VPLS or VPRN services on the 7450 ESS or 7950 XRS. 
- 
Bind SDPs. 
- 
Configure interfaces (where required) and SAPs. 
- 
Create exclusive QoS and filter policies.
