Subject: Re: Re-engineering the public switched network
Following are a few paragraphs from my testimony in the CA ISDN rate case.
All of the Bells offer X.25 Packet capability, to varying degrees. If they
would complete the implementation of the ISDN-X.25 interconnection (which is
almost there), and offer it under appropriate tariffs, then it would be up
to ISPs to offer the server-side capabilities to take advantage of this. We
are demonstrating this very exciting application in our lab today. It's
perfect for electronic mail.
For lower-bandwidth requirements, ISDN technology includes something called
"D-channel X.25." This service gives the ISDN customer access to the Public
Packet Switched Network without tying up circuit-switching resources. It is
particularly useful for small transactions, like credit card verification,
E-mail transmission, or other short messages. Unlike circuit-switched
technology, with X.25, transmission facilities are only tied up when data is
actually being moved.
6) As noted above (see Q14), ISDN provides access to the X.25 packet
network, which can be particularly useful for certain applications. In fact,
in combination with other attributes of ISDN, X.25 can contribute to a
compelling offering for some customers. Pacific has proposed raising the
charge for access to the X.25 network via the ISDN D-channel to $5. Usage
rates for X.25 need to be revised given the new role that this relatively
old network is now taking on in today's environment. Current X.25 usage
rates, which charge according to the amount of data transferred, amount to
many, many times more than the charges incurred for comparable data
transfers using modern modem technology and measured analog telephone lines.
Revision of the rates is justified given the more cost-effective access to
the packet network provided by ISDN and new applications that will drive
X.25 utilization. The monthly access charge should be set high enough to
permit it to include an allowance for usage that would accommodate typical
customers; I recommend a monthly allowance permitting transfer of 20
megabytes of X.25 data without additional charge. Further, Pacific still has
several digital switches that are not fully connected to the X.25 packet
network; there should be plans in place to complete this interconnection by
the end of 1996.
