Speaking to the press, Mr.Jagadish Vadalia, Senior Manager of Product Development said, “Multilink PPP (ML-PPP) and PPP allow splitting, recombining, and sequencing of packets across multiple data links into a single logical pipe or bundle. This is quite useful when you need more than one T1 or E1 line capacity but not as much as a T3 or E3. For example 5 separate T1 lines can be used as a "single pipe". He added, “ML-PPP has wide application for access lines to Internet Service Providers (ISPs) and enterprises that need "single pipes" greater than 1 T1 or E1 but less than 28 T1s (T3) or 16 E1s (E3). ML-PPP is similar to IMA (Inverse Multiplexing over ATM), in the sense that larger bandwidth is derived by aggregating smaller physical channels”.
Mr. Vadalia further added, “When a single T1 or E1 line is adequate bandwidth for an enterprise, plain old PPP is used. PPP or Point-to-Point Protocol is a link layer protocol, which encapsulates other network layer protocols such as IP. It is generally based on HDLC frame structure”.
GL has provided several software applications for analyzing and emulating ML-PPP, and PPP, and the below links provide comprehensive information on ML-PPP / PPP Analysis and Emulator Software:

About GL Communications, Inc.
Founded in 1986, GL Communications, Inc. (gl.com) is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards and solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (HDLC, ISDN, SS7, CAS, GSM, GPRS, CDMA), and with capacities up to thousands of channels.
GL’s VoIP products generate / analyze thousands of calls simultaneously with traffic types such as voice files, digits, tones, noise, and fax using G.711, G.729, AMR, EVRC, and GSM codecs. Additional features include visual analysis, real-time listening, recording, and voice quality assessment using ITU algorithms PAMS, PSQM, and PESQ.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and CDMA 2000 networks. Connections can be made to any wireless phone with automated call control, GPS, mapping software, and real-time signal measurements.
GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160. Network Surveillance and Monitoring products include Probes for TDM, VoIP, ATM, and Wireless networks.
