GL Conveys the Availability of its Product PacketExpert Quad Port Ethernet / VLAN / MPLS / IP / UDP Tester

Gaithersburg, Maryland (PRWEB) June 16, 2012

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its product PacketExpert – portable (USB based) Quad Port Ethernet / VLAN / MPLS / IP / UDP Tester.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager said, PacketExpert is a portable (USB based) Quad Port Ethernet / VLAN / MPLS / IP / UDP Tester with 4 Electrical Ethernet Ports (10/100/1000 Mbps) and 2 Optical Ports (1000 Mbps). It connects to a Notebook PC through a USB 2.0 interface. Each port provides independent Ethernet/VLAN/MPLS/IP/UDP testing at wire speed for applications such as BERT, RFC 2544, and Loopback. It truly takes confusion out of Ethernet testing at all protocol layers – from Layer1 frames to IP/UDP packets. It can be used as a general purpose Ethernet to IP performance analysis tool for 10 Mbps, 100 Mbps and 1 Gbps Ethernet local area networks and wide area networks. Two of the 4 ports have both Electrical and optical interfaces, enabling testing on optical fiber links as well.

He added, PacketExpert provides 3 important functionalities Wire speed BERT, Smart Loopback, and RFC 2544 Testing. It can perform Wire speed BERT (Bit Error Rate Testing) on all ports simultaneously over Layer1, Framed Ethernet (Layer2), Stacked VLAN (Q-in-Q), Stacked MPLS (Layer 2.5), IP and UDP. It can generate and receive various BER patterns, including various PRBS patterns, to properly test the Ethernet to IP link. It analyzes the received BER traffic and provides various vital measurements such as Bit Error Rate, Bit Error Count, Sync Loss Count, Sync Loss Seconds, and Error Free Seconds. PacketExpert also gives a real time graphical representation of the Bit Error count, plotted over time.

Mr. Vadalia further added, PacketExpert supports Throughput, Latency, Frame Loss and Back to Back test as specified in RFC 2544. Similar to BERT, RFC 2544 testing can be done over Framed Ethernet (Layer2), Stacked VLAN (Q-in-Q), Stacked MPLS (Layer 2.5), IP and UDP. The results can be viewed in tabular as well as graphical format. It also generates reports in pdf and csv format for the RFC 2544 tests and BERT. With the capability to generate/receive traffic with stacked VLAN (Q-in-Q) and stacked MPLS, PacketExpert finds use in testing a wide range of networks from testing individual links/switches, testing local Ethernet/IP networks (LAN), end to end testing of Wide Area Networks (WAN), testing Core/MPLS networks, and much more.

Analog Terminal (FXO) and Network Port (FXS) Testing Using tProbe Client Server

Gaithersburg, Maryland (PRWEB) September 18, 2012

GL Communications Inc. announced today the release of its enhanced tProbe with FXO/FXS ports that can also support dual T1 E1 ports, dual datacom ports, dual VF In/Out ports, and an Ethernet port.

Speaking to reporters, Mr. Jagdish Vadalia Senior Manager of Product Development for the company said, FXS and FXO are ports used by analog phone lines or phones. A Foreign Exchange Subscriber (FXS) port supplies ring voltage, battery current, dial tone and voice signals. Foreign Exchange Office (FXO) delivers an on-hook/off-hook indication (loop closure), DTMF digits, voice signals, and is usually a phone or fax machine.

He added, The FXO and FXS ports on GLs tProbe unit simulates all of the above features. Also, the FXO port on the tProbe permits non-intrusive capture and analysis of voiceband signals from a two-wire telephone line.

Mr. Vadalia explained, In a typical testing scenario of tProbe FXO Port to Mobile or Landline Phone , the call flow depicts the call from tProbe FXO port to the Landline or Mobile phone through the wall jack FXS, local PBX, and central office of the service provider and base station. With the tProbe FXO call script, one can perform the basic operations during the call setup such as the Off-hook/On-hook, check dial tone, transmit DTMF digits, monitor ring signal, and handling traffic.

In a testing scenario of tProbe FXS Port to a Regular 2-wire Phone, the call flow depicts the call from tProbe FXS port to regular phone (2-wire phone) via RJ-11 cable. This test places the ring to regular phone (2-wire phone), captures the incoming traffic into the file and transmits traffic to the other end. With the tProbe FXS call script, one can perform the basic operations during the call setup such as monitoring Off-hook/On-hook, send dial tone, monitor DTMF digits, send ring signal and handling traffic.
