JDS Uniphase HST-3000 Ethernet SIM Product Manual

HST-3000 Ethernet SIM

Test Electrical and Optical Ethernet up to 1G

Key Features

• Electrical and optical Ethernet testing in one module

• Traffic generation at full line rate or variable loads to test
services at layer 2 and 3

• ‘Thru Mode’ to measure live traffic

• Cable diagnostics to identify and locate electrical faults

• Scripted RFC 2544 benchmark testing

• Loopback L2 or L3 traffic from any instrument in JDSU’s
Ethernet portfolio

As networks migrate from circuit-switched to packet-switched architectures,
Ethernet services are being pushed out of the network core and toward the edge.
Therefore, service providers must equip their technicians to adequately turn up
and troubleshoot this new technology while continuing to support their legacy
T/E carrier services.

While the majority of today’s Ethernet links carry only data traffic, Voice over IP
(VoIP) and IP Video are becoming more common. These triple-play networks,
which transmit voice, video, and data traffic, present a unique set of challenges.
Service providers for these network environments are now responsible for
delivering a layer 7 service, rather than a traditional layer 2 or layer 3 pipe.

The HST-3000, equipped with the Ethernet Service Interface Module (SIM),
addresses this requirement for 7-layer testing in a rugged, modular platform that
is ideal for field use. It has a full Ethernet feature set for testing both electrical and
optical links with data rates up to 1 Gb/s. The HST-3000 also offers multiple
stream support for the verification of prioritization schemes and advanced
monitoring options for advanced troubleshooting capabilities. In addition, the
HST-3000’s VoIP and IP Video options allow technicians to emulate the end
customer’s user experience and objectively measure quality of service.

Layer 2 Packet Testing

The HST-3000 Ethernet SIM provides technicians with layer 2 packet testing
capabilities, allowing for the generation of Ethernet frames with various
configurable parameters, such as bandwidth utilization, frame length, and frame
payload. These frames can be generated with constant, ramp, or bursty traffic load
settings to fully test the Ethernet service.

Layer 3 IP Testing

The HST-3000 Ethernet SIM enables technicians to generate and receive IP packets
with its built-in layer 3 testing capabilities. These packets have a valid IP header,
containing user-defined fields, such as TTL, TOS/DSCP, source IP address, and
destination IP address. Since dynamic addressing is supported, the source IP address
can be assigned by a DHCP server, if necessary. Basic domain name service (DNS)
testing can be performed to ensure that the DNS server is able to resolve the name
to the appropriate address. In addition, traffic load settings can be configured for
constant, ramp, and bursty traffic in order to simulate different network traffic
conditions and analyze the performance of the link.

One-Button RFC 2544 Automation

To verify that service level agreements (SLAs) are met, service providers must run a
full suite of tests at turn-up. This set of standard tests, known as RFC 2544, is
wrapped into an easy-to-use auto test on the HST-3000.With one press of a button,
the link is configured with the technician’s saved settings and tested against
customizable thresholds. This ensures that the test is performed the same way every
time, providing consistent, repeatable results.

Cable Diagnostics

On electrical Ethernet circuits, the HST-3000 can display the link speed, link status,
cable status, MDI/MDIX, and distance to fault with one press of a button. To verify
connectivity on fiber lines, the HST-3000 reports the power level of the optical
signal. These features allow technicians to quickly sectionalize physical layer
problems.

Bi-Directional Monitoring/Thru Mode

The dual ports (both optical and electrical) on the HST-3000 Ethernet SIM enable
technicians to gain access to circuits under test in order to perform in-service
monitoring in both directions. Not only does this simplify sectionalization of the
network, it also allows for the analysis of live customer traffic without the use of a
splitter.

VLAN Protocol Support

VLAN tag manipulation allows for the generation of an Ethernet traffic stream with
a specific VLAN ID (as per specification 802.1Q) and VLAN user priority (as per
specification 801.P). This enables technicians to verify the correct transmission and
prioritization of the stream through the network. In addition, VLAN filtering allows
technicians to isolate a specific VLAN stream and compare its performance with the
total performance of the link. VLAN protocol support is available for both layer 2
and layer 3 traffic frames.
