ABSTRACT: Issue 1 of GR-1060, Switched Multi-Megabit Data Service (SMDS) Generic Requirements for Exchange Access and Intercompany Serving Arrangements, provides the Telcordia view of proposed generic requirements for Exchange Access Switched Multimegabit Data Service (XA-SMDS), and serving arrangements between Independent Local Exchange Carriers (ILECS) and client companies to support Switched Multimegabit Data Service.

SMDS is a high-speed, connectionless, public, packet-switching service that will take LAN-like performance beyond the end-user's premises, across a metropolitan or wide area. In the public switched telecommunications environment, a Local Exchange Carrier (LEC) provides two services:

• An exchange service provides telecommunications between end-users within an exchange area. For exchange services, the end-user is the customer of the LEC.
• An exchange access service provides telecommunications for the purpose of originating or terminating interexchange services. The Interexchange Carrier (IC) uses exchange access to originate and terminate telecommunications between source and destination end-users. The source end-user is the customer of the IC for the interexchange services. The IC is the customer of the LEC for originating and terminating exchange access services.

• A definition of the features of XA-SMDS
• Client company-ILEC serving arrangements to support the features of Exchange and Exchange Access SMDS
• The specification of the ICIP
• Performance and quality of service objectives
• Usage measurement requirements to support billing.
