GL Communications (News - Alert) Inc. recently announced the official launch of its product OC-3 STM-1 and OC-12 STM-4 Analyzer software for POS mode. Both products will now be available for purchase.

Some of the key features are Packet Count, Rx Minimum and Maximum Packet Length Violation Error Count; wire speed cell generation and processing on single or multiple ports using internal logic; capture and analyze Point-to-Point Protocol (PPP) over SONET/SDH as per RFC 2615; ability to support rates of 155.52 Mbps for OC-3 and 622.08 Mbps for OC-12 interface; supports payload scrambling of polynomial 1+X^43 and the ability to support up to 16 128-bit hardware filters.

In a release, Vijay Kulkarni CEO of GL Communications said, “Packet Over SONET (PoS) is a highly scalable layer 2 protocol that uses PPP encapsulation to carry IP packets directly in SONET/SDH networks. Currently it carries a majority of the Internet traffic because it can make efficient use of existing SONET infrastructure. The protocol uses practically all optical interfaces as defined by the Internet Engineering Task Force (IETF).”

Other key features include SONET Statistics: Link State, Line Speed, Section LOS, Section LOF, Section BIP (B1), Line AIS, Line RDI, Line REI (FEBE), Line BIP (B2), Path AIS, Path RDI, Path REI (FEBE), Path BIP (B3); Packet statistics: Tx/Rx Byte Count, Tx/Rx Packet Count, Rx FCS Error Count, Rx Abort and IP Statistics: IP Packets Received, IP Checksum Errors, , UDP (News - Alert) data over IP Layer frame count.

Kulkarni continued “GL’s OC-3 STM-1 and OC-12 STM-4 analyzer is referred to as LightSpeed1000 analyzer supports Packet over SONET / SDH (PoS) at OC-3 STM-1 and OC-12 STM-4 at full rates over dual interfaces. Access, capture, analysis, and emulation of PPP and HDLC, all carrying IP traffic in real-time makes this card useful to many applications including Routing, Deep Packet Inspection, and other Internet traffic applications. Multiple cards can be installed in a PC making it scalable to monitor or generate OC-3 or OC-12 traffic on multiple ports. Each port on a card can work independent of others, which extends analyzer's flexibility as test equipment.”
