超强可靠性的保障：N＋1
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.
Features:
- Facilitates maintenance without loss of service
- Protects against TB640 interruptions
- Scales from 1:1 to 15:1
- Compatible with the TB-Multi-blade™
