Calling number ID runs into trouble.

Calling Number ID Runs Into Trouble Calling number identification is a crucial ingredient in ISDN applications, but it is threatened by courts, law-makers, and special interest groups.

Steven Horne of Bellcore, speaking to a session of the North American ISDN Users Forum in Dallas, said, "Mass market availability of CNI is a major component of ISDN applications. But it is important to others, too, in terms of privacy."

The users forum was in conjunction with the Interface show.

Proponents of calling number ID say it enhances privacy for the called party, reduces obscene or harassing calls, improves response of police and firefighters, and increases business efficiency up to 20%.

But, said Horne, opponents say it discourage calls to anonymous help hotlines, passes unlisted numbers along with listed numbers, and discourages the "expectation of anonymity" of the calling public.

CNI's ubiquity is at stake. In some states, callers can block their number from showing up to the called party. In New Jersey, there is no blocking. In California, a new law directs state regulators to determine the best way to institute per-call blocking. In Pennsylvania, a judge put Bell Atlantic's CNI on hold, saying it may violate state wiretap laws.

Asked if the called party, in response to blocked numbers, could screen out any call that won't deliver its number, Horne said a provision for that is in CCITT standards.

Horne urged forum attendees to make their voices heard and lobby for their point of view.

Does ISDN have a future?

ISDN will become universal, Walt Roehr of Telecommunication Networks Consulting predicted in a panel on ISDN Pros and Cons. He predicted the day when ISDN will be available at Radio Shack, as POTS is today.

Joaquin Gonzalez, Global Networking Strategies, disputed Roehr's viewpoint vigorously. He said ISDN, as a transport capability, has been leapfrogged by T1.

During the debate, he maintained the future will belong to fast packet and circuit switching, distributed fault tolerance, advanced data-voice compression, and modular packaging.

Philip Evans, telecomm manager for FMC in Dallas, said he is evaluating ISDN. As a user, he sees it as an integrator of existing services rather than a provider of new things.

Without spending money on ISDN, Evans said he reduced backbone network costs by 70% over the past several years.

Other points about ISDN raised at the forum and Interface:

* ISDN users need a security policy, and encryption is only one answer, said Jonathan Katz of The Analytic Sciences Corp.

"There are no definitive ISDN security architecture documents or any standards covering ISDN security," he said.

* The future of ISDN is in the MIS department, said John Saccente of Telecommunications Consulting. "There is no future is selling it as the greatest new phone system to the voice department."

* Advice from Tony Tissot of Rolm: try ISDN as soon as possible. He said the best way for a user to get feet wet was by getting in on a vendor's trial.

* Any national telemarketer or service organization not already using automatic number identification is Late, said Michael Kennedy of Arthur D. Little.

Kennedy predicted ISDN ubiquity in about 10 years.

* One measures of ISDN's increasing acceptance, said Myra Wright of West Virginia University, is that people know what it is without breaking down theacronym.

* Vincent Lobry, France Telecom, maintained ISDN means "It Suits Diversified Needs".
