Direct Access To T1 E1 DS0 On OC-3/12 STM-1/4 On LightSpeed1000™
Voice, data, and video traffic is exploding as smartphones, IP TV, video streaming, and "cloud" based services takeoff. A majority of the backbone transport for these applications continues to be SONET and SDH optical transmission networks. A dominant protocol for IP transport is PoS (Packet over SONET) and another is ATM (Asynchronous Transfer Mode). Both schemes are packet based, with ATM using fixed size packets of 53 bytes called "cells", and PoS using variable packet sizes closely matching to Ethernet frames.

MC-MLPPP Analyzer And Emulator
The Point-to-point protocol (PPP) is a link layer protocol, which encapsulates other network layer protocols like IP for transmission on synchronous (like T1/E1) and asynchronous communications lines. When transmitted over T1/E1 line, PPP frames are based on HDLC frame structure. Two major features of PPP protocol are:*Authentication*Encapsulation of higher layer protocols

Fax/ Modem Testing
To successfully deploy fax services requires extensive network design, test and traffic engineering. Test equipment can prove valuable in this process, if it can: Generate and receive fax signals in bulk over wired and wireless networks, monitor and distinguish fax signals in real time for traffic engineering and network design purposes, and analyze fax signals after capture for troubleshooting failed or poorly handled calls.
