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 identifi-
cation. 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 in-
formation will be available when needed.
