TelcoBridges 超強(qiáng)可靠性的保障：N＋1

　　在可靠性要求很高的場合，板卡硬件損壞造成的損失將是可怕的，但是TelcoBridges的N＋1設(shè)備能夠避免單板卡損壞造成的損失，提供超強(qiáng)可靠性。它采用一塊TB640熱備的方式實現(xiàn)板卡硬件級的冗余。特點：

在系統(tǒng)發(fā)生故障、備用板卡替代損壞板卡時，不會丟失服務(wù)

　　The TelcoBridges' system-on-a-blade solution has the reliability, flexibility and superior performance to replace any 8-64 trunk telecom system with a single blade. In addition, the bridging of multiple blades can easily increase a single system capacity up to 1024 trunks using our innovative Multi-blade.
TelcoBridges' unique TB640 System-blade? offers:

Dynamic configuration

Proven flexibility

Unmatched density

　　The TelcoBridges N+1 solution facilitates flexible maintenance without loss of service, and protects the system against any interruption of a TB640 blade connected to the N+1 patch box.
　　The solution comprises up to fifteen active TB640 blades connected to the network through the N+1 patch box, plus one standby TB640 blade waiting to be connected to the network in case of need.
　　The standby TB640 blade can takeover at any time any one active TB640 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 active blades plus one standby 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.
　　The TB640 blades attached to the N+1 blades also provide the low power needed by the system.
