The TelcoBridges N+1 Shelf family of products were specifically designed to facilitate maintenance and protect the system against any interruption of a TB640 System-Blade™ connected to the N+1 Shelf.
For example, the TB-N+1-16 Solution comprises up to fifteen primary TB640 System-Blades™ connected to the network through the N+1 shelf, plus one redundant TB640 blade waiting to be connected to the network in case of need.
The redundant TB640 System-Blade™ can takeover at any time any one primary TB640 System-Blade™, so re-routing the traffic to the redundant blade until the necessary maintenance is completed.
The N+1 architecture is compatible with the TB-Multi-Blade™ architecture. With N+1, fifteen primary blades plus one redundant blade can be fully interconnected to create a non-blocking switch of 960 trunks.
Control, maintenance and diagnostics are all provided through TB640 API calls, with a full set of easy-to-use functions for complete system status monitoring and control.
N+1 blades can be added live to a system with no downtime. This means the system can scale from a 1:1 to 15:1 protection while it is still running. The TB640 System-Blades™ attached to the N+1 blades also provide the low power needed by the system.
