Section 9(v) in Regulation on Quality of Service of Dial-Up and Leased Line Internet Access Service, 2001
(v)At Present, the link between the PSTN node and the ISP node (RAS) is being provided by adopting a 'rule of thumb' approach. Typically, one time slot is provided to cater to the traffic generated by 20 customers. Since such an approach may result in either over-provisioning or under-provisioning of resources (time slots on E1 links or physical pairs), it is mandated that the Basic Service Operators (BSOs) measure the Grade Of Service, every quarter, by suitable manmachine commands and, if required, the ISP should augment the resources to guarantee a Grade Of Service of I in 100 on the link as specified in Section IV of this regulation.
