Press Release: GL Announces TDM, Optical and Packet Integrated Platform for Test and Measurement

Gaithersburg, Maryland, USA – April 18, 2018 - GL Communications Inc., announced today its TDM, Optical and Packet Integrated platform for Test and Measurement referred to as mTOP™ platform.

Speaking to the press, Mr.Vijay Kulkarni, the CEO of the company said, “The new Multiple TDM, Optical and Packet (mTOP™) rack enclosure can house any combination of USB based test equipment – PacketExpert™, tProbe™ (T1 E1), USB T3 E3, Dual UTAs, & LightSpeed1000™ to support multiple interfaces in a compact rack space.  mTOP™ systems not only provide space efficiency, but also account for easier scalability and reduced licensing cost per port.”  

He added, “Each mTOP™ enclosure is a sleek 1U or 2U enclosure with the ability to support up to three GL USB based test hardware units. For scalability a secondary mTOP™, also housing three GL USB based test units can be connected to the primary mTOP™ using same software and licenses. Mixing different GL USB based test equipment (any TDM/Optical/Packet combinations) within same mTOP™ is also possible.”

Mr. Kulkarni further explained, “VQuad™ mTOP™ solution is an all-in-one self-contained VQuad™ with Dual UTA HD test instrument designed for conveniently testing up to 12 independent telephony devices including Analog 2-wire FXO, Analog 4-wire, Phone Handset (RJ22), Mobile Radio with PTT, and Mobile Phone (Smartphone/Handset) for a variety of testing and analysis.

The VQuad™ solution supports Wireless as well as 2-Wire and 4-wire analog calls using same hardware. User can perform simultaneous Voice, Video, Data, Fax, and Time Delay Measurements from a single VQuad™ mTOP test solution - greatly reducing the licensing costs per device.

Almost all of T1 E1 and T3 E3 Testers can be accommodated into rack-based units. Multiple rack units can be stacked together for greater scalability.

High Density PacketExpert™ of 12/24 GigE ports form factor solution are used for testing multi-port switches, routers and networks end-to-end. Each of the 12/24 GigE port supports auto‐negotiation and flow control. The chassis comprises of both electrical and optical (fiber) interfaces. The Electrical ports can operate up to 10/100/1000 Mbps line rates in Full Duplex mode, while Optical ports can operate up to 1000 Mbps line rate in Full Duplex mode. A single PacketExpert™ mTOP™ test solution with stacked rack units greatly reduces the licensing costs per device.”

He added, “mTOP™ can also provide  for unified testing experience of Ethernet /IP, TDM and Optical technologies. It can perform as an all-in-one performance analysis tool allowing tests to be performed at any end points.”
