Dial-in with redundant Ethernet

A major telephone company set up several thousand dial-in ports for employee telecommuting. Their objective was to set up a fully redundant system while limiting the number of computer connections required to approximately 1500.

PROBLEM: Provide an affordable low-cost redundant solution that can prioritize the callers into call groups for selective access. When lines begin to fill up - some users have more priority than others. Added problem of a large DEC site that the host computers used proprietary buses.

SOLUTION: Establish a dual rail Ethernet for network redundancy. Place 6 ABLE PL550s on each Ethernet segment ( 768 ports each). Connect PL550s and CS128 MuxMaster port concentrators to redundant NC3600 network exchanges. Perform auto-sysgen, establish prioritized hunt groups and fall-back scenario - get users on-line.

All PL550 ports are grouped into a hierarchical structure of service groups that are connected to in a manner that balances the load across the PL550s. If a PL550 fails, the effect is negligible as the incoming ports share the other PL550 ports automatically. Even if a complete Ethernet segment goes down, Until it is repaired, the remaining PL550s are available to the dial-in users and can be further prioritized in this event. The NC3600 Exchanges are fully redundant and share the same network connection image. All 16 port modules in a CS128 Port Concentrator can be replaced LIVE - ON-LINE, without disturbing other user ports.

It is obvious that a telephone company understands the efficiency and cost savings by port contending a shared resource. In this case the administrators wanted to be sure that Executives would ALWAYS have access and then prioritize the rest. Truly - Rank has its privileges !
