Black Lion Telecom has many large IBM z/OS mainframe systems running a mixture of in-house and vendor products to deliver their core telecommunications applications and support their corporate business needs.
Their internal data network is mainly SNA-based, supporting communication between their large central data centers and many geographically remote regional control centers. They also have a small but growing z/OS IP network.
For the past fifteen years, Black Lion Telecom has been using Tivoli NetView to manage their mainframe SNA network. Many of the Tivoli NetView SNA management features are used, but the core of the network operations work is done with NCCF.
New corporate business and IT alignments have forced an evaluation and justification of long-term mainframe software costs at Black Lion Telecom. As a result of this evaluation, management has decided to change to CA NetMaster NM for SNA and CA NetMaster NA.
