Pat responded that Cornet is AT&T's internal phone system. Pat's partially correct. About three years ago, I recall seeing a company bulletin saying Cornet was being phased out in favor of an internal Software Defined Network. Cornet was limited to certain parts of the company (Bell Labs and former Western Electric locations?). In six years with AT&T, I've never directly encountered it, although I saw some references. If memory serves, Cornet was a tandem network. Much of the traffic was carried over dedicated lines running from switch to switch. It did provide seven-digit dialing anywhere in the country. Assuming I'm right, then AT&T Long Lines would have issued billing for the dedicated lines connecting the switches, WECo handled the equipment leasing, and millions of ratepayer dollars paid for the internal accounting!

Cornet (CORporate NETwork) is indeed being phased out (if not almost all gone). It was used extensively at Bell Labs and Western Electric. CORNET was provided using a network of 1ESS Switches, and then replaced recently by 5ESS Switches. (This same service is/was sold to many large and medium-sized businesses.) This service was replaced by SDN. SDN provides for ten-digit dialing whether using private network facilities or more expensive public facilities. This means the user (employee dialing the phone) need not worry about that. The service provider (AT&T-NSD) takes care of this for the customer (Bell Labs) without each user having to understand any of this. Also, it eliminates the need to remember TWO phone numbers.
