MultiLink Point-to-Point Protocol CTI's most popular modem for using MLPPP is the Hayes OPTIMA |
The Multilink protocol is available on PCs who have either Windows 95 or NT operating systems. Simply stated, this protocol allows you to use more than one modem to link into remote locations where Multilink has also been configured on their end. An individual telephone line connection is required for each modem that is to be linked through the use of Multilink. CTI's FastSync Client/Server Mailbox System can be setup to take advantage of the file transfer throughput benefits.
Here is various information covering MLPPP...

Multi-Link PPP |
Now, you can combine the bandwidth of two or more physical communications links to increase your remote access bandwidth and throughput using RAS Multilink. Based on the IETF standard RFC 1717, RAS Multilink lets you easily combine analog modem paths, ISDN paths, and even mixed analog and digital communications links on both your client and server PC. This will speed up your access to the Internet or to your Intranet and cut down on the amount of time you have to be remotely connected so it can reduce your costs for remote access. Details: http://www.microsoft.com/communications/ras40.htm |
Windows NT version 4.0 provides support for phone-book subentries, which enable multilink connections. A multilink connection combines the bandwidth of multiple connections to provide a single connection with higher bandwidth. Note: The latest release of Windows 95 and their DUNs software also supports MLPPP.

Problem from Tom Cox via E-mail - Answer from Sean Daily. Problem: "I tried to use this feature [MLPPP], but none of the ISPs in my area allow more than on user to logon at once, so the dial-in fails. Is there a way to set a dial-up connection to use multiline access and automatically log on under two usernames or tell the browser to use all facilities available? I have two accounts for different purposes, but I want to access both at once for greater speed on the Internet. I'm using Windows NT Server 4.0 with Service Pack 3 (SP3) and Internet Explorer (IE) 4.01." Answer: "The behavior you experienced resulted from the type of connections you created. You created two separate connections via two distinct Point-to-Point Protocol (PPP) sessions to ISPs, each of which NT treated as a separate interface with a unique IP address. In this scenario, a TCP/IP session typically uses only one route (via only one of the RAS PPP sessions) to establish a connection to a remote host. For RAS to utilize the MultiLink RAS (Multilink PPP) feature and use two or more connections as one virtual connection, the other end of the connection (i.e., in this case the ISP) must be using NT Server 4.0 RAS with MultiLink RAS support or another type of network access server that's compatible with NT's MultiLink RAS feature. Unless this specific support exists, you won't be able to use the MultiLink RAS feature. I've heard about several ISPs that support NT MultiLink RAS, but such support is still very rear. As more ISPs increase the deployment of NT within their organizations, support will probably increase." |

| According to PC World..."Many people who can't get two modems to work are using PCs incapable of handling an extra modem. If your system came with two serial ports and a PS/2 mouse port, you can easily plug in two external modems. But if there's only one serial port, or if one must be used for the mouse, you're in trouble. Installing an internal modem won't work well either. Your computer see an internal modem as another serial port; and though a PC can have up to four serial ports, you can't use ports 1 and 3 at the same time. Or ports 2 and 4. So you can't simultaneously use two modems and a mouse if the mouse is plugged into a serial port." | ||||
