The core service for Host Networking, a combined service assurance and service delivery organization, is to provide remote, 7x24 support for software that facilitates communications to and from mainframes which are connected to the IBM network and/or AT&T network, globally.

We also support, in some instances, connectivity to the customer via IBM, or from the customer to AT&T via EVPN connections, and some elements on non-mainframe servers.

Alternate pricing models are currently under investigation that may include limited hours of support, e.g. 9 – 5.
