SDH APPLICATIONS 

Installation, commissioning, monitoring and maintenance of SDH and PDH networks simplified thanks to a combination of intuitive features 

and powerful test functions. SDH signals are often compromised by various impairments in the multiplexing process therefore defining the 

type of anomaly or defect to isolate the network element or signal path causing the problem is crucial. Fast troubleshooting and comprehensive 

analysis of transmission problems can be performed using intrusive, non-intrusive and monitoring test modes. Novice users will benefit 

from the easy-to-use Auto-configuration and Tributary Scan test modes, while experienced users will appreciate the array of advanced 

features such as Overhead Monitoring and Byte Control, Pointer Test Sequences, Path Trace generation, Tandem Connection Monitoring and 

lots more.

PAYLOAD MAPPINGS SUPPORTED 

(PER ITU-T G.707 RECOMMENDATIONS) 

The SDH Multiplexing principle basically consists of; 

▪ Mapping - Tributaries are adapted into Virtual Containers (VCs) 

by adding justification bits and Path Overhead (POH) 

▪ Aligning - Addition of a Pointer to a Tributary Unit (TU) and 

Administrative Unit (AU) for identification of the VC 

▪ Multiplexing – Low order path signals are adapted into high order 

path signals, or high order signals are multiplexed 

The TX300E tests the proper operation of Add/Drop 

Multiplexers, Digital Cross Connectors and other Network 

Elements (NE) by verifying the mapping and de-mapping 

of different tributaries and payloads into SDH containers 

and monitors anomalies and defects associated with 

each process. 

The Payload and Path Overhead of each SDH Container 

(VC) including the Pointer associated with the PDH 

tributary can also be monitored.

QUICK AND EASY GRAPHICAL SETUP 

Complex daily tasks is common in today’s network environment, 

therefore technicians need a tester that is quick and easy to 

configure. Intuitive graphics, drop down menus and touch panel 

operation greatly simplify test interface, signal structure, payload 

mapping and test pattern setup.

▪ Bridge: ≤ 6dB (cable loss) 

For 34.368 Mbit/s (E3); 




PHYSICAL LAYER TESTING 

Verifying analog parameters are within prescribed specifications 

and limits is recommended prior to performing framing and 

payload analysis. High optical power levels can saturate receiver 

equipment, while low power levels are susceptible to noise which 

result in bit errors. 

Clock tolerances for each individual signal hierarchy is clearly 

defined by Bellcore / ITU-T recommendations and should be 

verified as part of any acceptance/conformance test. 

PERFORMANCE ANALYSIS SUMMARY 

Performance of each hierarchy is based on byte interleaved parity 

(BIP) checksums which are calculated on a frame by frame basis. 

These BIP checks are inserted into the Regenerator, Multiplexer 

and Path Overhead all of which form an integral part of the performance 

monitoring capabilities of an SDH/SONET network. 

The TX300E analysis screens present Pass/Fail criteria for each 

performance parameter according to ANSI/ITU-T recommendations 

as applicable.

The objective of Optical Transport Network (OTN), Digital Wrapper Technology, is to combine and accelerate the benefits of SDH with 

the bandwidth expandability of dense wavelength division multiplexing (DWDM). OTN applies the OAM&P functionality of SDH, allowing 

for protocol transparency, optimized error-free transmission, and reduces the number of 3R regeneration points in an optical network. 

This enables operators to cost effectively install, maintain and scale their next generation networks.

Ethernet Applications 

End-to-End Performance Testing 

Irrespective of the Ethernet service being installed, it is always necessary to verify that the network can carry out and cope with the allocated 

bandwidth required by the customer. Service Level Agreements (SLA) thus compel Service Providers to measure network throughput and other 

performance characteristics to ensure that bandwidth associated with different service types conform to customer expectations. 

10GE DWDM-based Service Testing Application 

▪ Perform Layer 1 Unframed BERT to verify the physical layer 

▪ Perform Layer 2 BERT/Throughput test with valid Ethernet frames to verify end-to-end transport 

▪ Verify end-to-end QoS parameters: throughput, frame loss, round trip delay, frame arrival delay, frame delay 

variation (jitter), out-of-sequence frames 

BER Testing

DWDM SDH 

ADM ADM 

Optical Ring 

One traffic stream is transmitted across the network under test 

and bit-per-bit error checking is then performed on the received 

traffic. Service disruption measurements as well as CRC error 

checking are also performed. The BER test can be performed with 

a physical loop (or plug) at the far end (for a layer 1 circuit), or 

a second test unit or intelligent loopback device in Smart Loop or 

in Peer-to-Peer mode.

ADM 

RFC 2544 

or or 

NID 

A single destination stream is configured with up to nine different 

frame sizes for recommended throughput, latency, frame loss, and 

back-to-back tests. Thresholds and maximum bandwidth settings 

are user configurable, allowing for fine SLA verification control. 

The RFC 2544 test suite can be performed with a second test unit 

or intelligent loopback device at the far end configured in Smart 

Loop or Peer-to-Peer mode for asymmetric testing.

Ethernet Features 

BERT 

Layer 1, layer 2, and layer 3 BER testing is supported. The BER 

test can be configured to use regular PRBS test patterns, stress 

patterns (specifically for 10Gigabit Ethernet) or user defined test 

patterns to simulate various conditions. All patterns are encapsulated 

into an Ethernet frame to verify bit-per-bit performance of 

circuit under test. 

Q-in-Q (VLAN stacking) 

For Metro and Carrier Ethernet applications VLAN stacking aka 

Q-in-Q is supported. This feature makes provision for carrier/ 

service provider assigned VLANs, but also retains the VLAN of 

customer traffic. 

Smart Loopbacks 

Three modes are available for looping back test traffic; layer 1, 

layer 2, and layer 3. 

▪ Layer 1 all incoming traffic is looped back unaltered. 

▪ Layer 2, all incoming Unicast traffic is looped back with the 

MAC source and destination addresses swapped. 

▪ Layer 3, all incoming Unicast traffic is looped back with MAC 

and IP source and destination addresses swapped. 

Delay and Jitter Measurements 

Frame Delay and Frame Delay Variation - Jitter measurements 

are performed on the test traffic during BER Tests or Throughput 

Tests. 

Multiple Streams Generation 

Up to 8 traffic streams can be independently configured with CoS 

(VLAN priority) and QoS (TOS/DSCP) prioritization. This traffic 

feature, simulates multiple service conditions (e.g. Triple Play), 

and facilitates end-to-end QoS performance verification. 


RFC2544 Compliance Testing 

Performs the RFC 2544 automated test suite at all recommended 

frame sizes including user configurable frame sizes and up to full 

line rate. The test suite can also be performed with the far end 

test partner in loopback mode or peer-to-peer mode – the latter 

allowing for symmetrical/asymmetrical testing. Thresholds may 

be configured for accurate SLA assurance and verification. The 

automated tests supported are throughput, latency, frame Loss, 

and back-to-back frames.
