In 1993 HCII designed and developed GTE’s electronic mail (email) infrastructure that runs on a world wide TCP/IP network with multiple email gateways to other networks and legacy email systems. This infrastructure was developed in conjunction with GTE’s Network Operations Center (NOC) project. The NOC project gave GTE the ability to monitor all central office locations and the phone network from a central location.

HCII designed and implemented:

• A system for global, corporate, and local network directory synchronization

• Cross platform graphical user interfaces (GUI) to access email

• A multiple server and multiple access email system on TCP/IP

• A general-purpose email handling protocol that allows emails to be read and stored anywhere on an IP network, transparent to the user and their location. This protocol was a precursor for the Internet protocol IMAPI that later became the Internet standard for remote email access.

• A Motif GUI for monitoring email gateways, including PC based gateways
