DS1 Connectivity Ordering
After the contract is signed, the sales representative or authorized dealer contacts
the DS1 connectivity vendor to discuss the T1/PRI service order. The vendor
needs information about the communications system as well as customer
identification. Table E–1
describes the kind of information the vendor requires.
This table should be reviewed with the customer’s network representative or
dealer so the information will be available when needed.
