TREND Networks R154000 - UniPRO SEL 1, GbE Loopback Device
 
UniPRO SEL 1
Part number R154000
GbE loopback device with single copper and optical ports
For use with UniPRO MGig 1
 
The TREND Networks UniPRO SEL1 (part number R154000) is a GbE loopback device with single copper and optical ports. It is used with the UniPRO MGig1 family of testers to eliminate the need for a full-fledged Ethernet tester at the distant end of the leased line or backhaul.

RFC2544
The testing technique in most common usage for service turn-up on access and leased line Ethernet services.

UniPRO MGig1 and UniPRO SEL1 cover all of the requirements for testing:
Throughput
Latency
Jitter
Frame loss
Back to back
System recovery
 
RFC2544 testing can be very time consuming, so UniPRO MGig1 provides a choice of test profiles from Super Fast to Full.

UniPRO MGig1 can perform RFC2544 testing in loopback or Bi-Directional topologies.

Why single engineer loopback testing is important
Using the UniPRO SEL1 intelligent loopback device means you don't need a fully-fledged Ethernet tester at the distant end of the leased line or backhaul. Even better, you don’t need to deploy a field engineer to the distant end either - instantly halving the labor cost of the testing.

Many operators simply mail a UniPRO SEL1 to the distant end with instructions to the recipient to plug it into the demarcation point or a spare switch port, turn the power on and leave it.

They take the view that some will not get returned - but the labour saving by not needing a second engineer covers those costs many times over. So they’re still significantly in profit.

The UniPRO SEL1 loopback unit can be completely remote controlled by the UniPRO MGig1 Ethernet tester at the near end. So its configuration is uploaded across the network within the test path and then its various loopback modes are controlled from a choice of layer 1 (physical or regenerative), 2, 3 or 4 as dictated by the test being performed by the near end UniPRO MGig1.

A second UniPRO MGig1 can also be used at the far end for loopback testing. In slave mode this is also remote controlled by a single engineer from UniPRO MGig1 at the testing site.
