AT&T Mainframe Networking - Technical Specialist in Toronto, Ontario

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.

Note: The preference today is not to provide onsite support or support accounts without connectivity to IBM or AT&T, and only to support a 24/7 model but each situation will be considered on its own merit. Alternate pricing models are currently under investigation that may include limited hours of support, e.g. 9 – 5.

Tier 3 support generally consists of installation, customization, and management of the supported software, including security compliance. z/OS communications server (TCPIP/VTAM), session managers, file transfer products, and print services products are the main categories of software.
