TelcoBridges 超强可靠性的保障：N＋1_语音板卡

超强可靠性的保障：N＋1

2005/03/28

　　在可靠性要求很高的场合，板卡硬件损坏造成的损失将是可怕的，但是TelcoBridges的N＋1设备能够避免单板卡损坏造成的损失，提供超强可靠性。它采用一块TB640热备的方式实现板卡硬件级的冗余。特点：

可以实现960E1的无阻塞交换

在系统发生故障、备用板卡替代损坏板卡时，不会丢失服务

备用板卡可以替代不同参数设置的任意一张主卡

　　TelcoBridges' innovative, ultra performing System-blade is in a class of its own. It allows telecom system integrators to compete effectively by offering a tailor-made option at an extremely affordable price.

　　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:

Easy integration

Dynamic configuration

Non-blocking architecture

Proven flexibility

High availability

Unmatched density

Superior scalability

1:1 to 15:1 …strength and flexibility with no loss of service

　　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.
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 blades attached to the N+1 blades also provide the low power needed by the system.
