Ottawa, CanadaBroadband test equipment maker Innocor adds what it claims is the industry/s first EoPDH (Ethernet over PDH) transport mechanism test capabilities to its existing TestPoint product line. The company also adds RPR (Resilient Packet Ring) test options to the mix.
PDH (Plesiochronous Digital Hierarchy) is used in networks to transport data over transport equipment such as fiber optic and microwave links. EoPDH refers to the transport of Ethernet traffic onto DS1, E1, DS3, and E3. It's accomplished by framing Ethernet in GFP (generic framing procedure), as defined in ITU-T G.7043/G.8040, or using HDLC.
It's expected that these methods of transporting Ethernet traffic will help service providers leverage existing infrastructure to deliver Ethernet services. Innocor's TestPoint approach is anticipated to let users map PDH signals onto a physical SONET/SDH optical link to test the EoPDH infrastructure and services.
The RPR Connection
RPR, as outlined in IEEE-Standard 802.17, defines a network protocol optimized for packet transmission in a resilient ring topology. TestPoint provides test features to intrusively inject and control RPR-level errors within an RPR ring.
Innocor's current implementation runs on OC-48/STM-16, where RPR maps into GFP. This RPR intrusive monitor feature lets you control and impair RPR traffic in order to measure the impact to the overall network.
"With Ethernet traffic at the core of more networks, test requirements are becoming more complex as companies need to support the multiple transport possibilities being enabled," notes Guylain Barlow, Director of Product Management at Innocor.
Barlow says EoPDH and RPR test capabilities are available as upgrades on the company's Multi-Rate Module for its TS-30 and TS-170 chasses, and on its TS-10 configuration. Innocor's TestPoint family, is a modular platform that supports versatility in configuring interface types, transmission rates, protocols, and port density.
