Lantiq MELT and Tollgrade’s Loopcare Integration
Lantiq and Tollgrade are partnering to integrate Lantiq’s advanced MELT
testing functions into Tollgrade’s broadband loop test systems
Tollgrade is the world leader in access network test systems, having an embedded base
of over 200 million lines under test across many of the world's largest
telecommunications carriers
The solution integrates Lantiq’s accurate MELT measurements using the
VINETIC-LTC128 + Smart SLIC-T16/MLT16 chipset into Tollgrade’s “tried-
and-true” measurement and dispatch algorithms to provide automated
“flowthrough” testing on low line count DSLAMs

DSLAMs are being replaced by smaller, more flexible and cost-efficient IP-based
solutions, that tend to be deployed much closer to the subscriber
Transition to All Digital Loop (ADL) and cabinet applications require new small/no

Lantiq MELT: Multi-channel Line Testing Solution for "All Digital" Loops
24h
Significant BOM Savings
Significant system cost advantage
+ no relays
+ no switching matrix (separate board)
Non-Stop Access
MELT In-Service testing works in parallel with DSL without service interruption
Frequent and parallel testing possible, support of up to 8 loops testing in parallel, 20 second test times for complete metallic suite of tests
Significant Power Savings
Extremely low (negligible) power consumption supports the European Code of Conduct requirements
fully compliant to the G.LT test standard from ITU
Lantiq’s MELT solution in combination with Lantiq’s next generation V/ADSL only requires Smart SLIC-T16/MLT16 separately, LTC integrated in DFE
Further BOM saving
Lantiq MELT is “the” MELT solution
Metallic Test Support for ADL (All Digital Loops) SELT plus MELT offers complete solution for fault location and periodic maintenance
DSLtechnology and supplier neutral

Lantiq’s Network Line Testing Philosophy
-Set not plugged in
-Wrong connector
-Broken cable (where?)
-Too many phones
-Manipulation by
subscriber
-Deteriorated cable
-Leakage to ground
-Construction Work
-Electrical hazard
-Mains power voltage
-Power Cross
-Power Induction

Lantiq MELT is:
Part of the ITU-T G.996.2 standard: “Single-ended line testing for digital subscriber
lines (DSL)”
Fully compliant to G.LT standard and supports VDSL2, ADSL2+ and SHDSL flavors
This chipset replaces traditional test heads and enables DSL loop testing through DSL line
cards where metallic line testing over POTS is no longer available
When controlled by Tollgrade test systems, MELT results can be integrated into OSS/ BSS
systems and trouble ticket processes for automated testing of DSL lines

Benefits of Tollgrade + Lantiq Test System Integration
Benefits when Lantiq MELT is added to existing deployments of Tollgrade test
systems:
End User Interfaces remain the same
Dispatch Statements do not change
Northbound OSS interfaces are not impacted and can therefore be reused
Benefits when Lantiq MELT is implemented as part of a new Tollgrade test
system deployment:
MELT test results are automatically analyzed and converted to easy-to-understand test
results and dispatch recommendations
Test system provides the user with common test results for multiple and mixed DSLAM
suppliers in the network
Test results can be benchmarked and stored for subsequent analysis
Installation and repair expenses are significantly reduced through the reduction of
unnecessary dispatches
MTTR and call handling times are reduced
Automation and flow-through of trouble reports reduces process cost and improves
efficiency
MELT tests can be performed from the field using integrated voice response or mobile
web access as part of trouble ticket close-out

Carriers using Lantiq MELT and Tollgrade Test Systems
Lantiq has been shipping MELT chips for field deployments with all leading
system suppliers
A considerable number of carriers have already deployed MELT in an “All-
Digital” environment, and it’s still growing
Tollgrade’s test systems are already deployed by some of the world’s largest
telecommunications carriers
