igital subscriber lines and
gradually ramp up to a projected 300 to 400 lines by the end of 1987. The
basic interface defines two 64K bit/sec B channels and a separate 16K bit/sec
D channel to carry data packets and signaling information.
All the products used in the trial are designed to communicate with AT&T's
5ESS switch. While the basic ISDN interface is sufficiently well defined to
permit different vendor's implementations to communicate, different vendors'
CO switch products still retain software incompatibilities.
The way terminal adapters communicate via ISDN is still defined by the CO
switch, terminals can be modified to communicate with either AT&T's or Northern
Telecom's ISDN switch, but you can't just unplug a terminal and move it from
one switch to the other.
Originally slated to be the first ISDN trail to begin operations, the
project was delayed for approximately a month while AT&T finished implementing
software on the 5ESS ISDN switch at Illinois Bell'
