What is Multilink PPP?
Multilink PPP combines two 64 Kbps ISDN channels to provide a maximum transmission
speed of 128 Kbps. The DIVA T/A serves as an intermediary between its host workstation and
the remote device to which data is being transmitted. All the protocol processing required
for the negotiation of a Multilink PPP connection is performed on the DIVA T/A itself. The PC
forwards asynchronous PPP packets to the DIVA T/A which, in turn, converts the packets for
synchronous transmission and negotiates the various authentications required to establish
the Multilink PPP connection with the target system over ISDN lines. This allows for the more
efficient use of the ISDN line without requiring any changes to the PPP stack currently loaded
on your PC.
DIVA T/A supports COM port rates of up to 230.4 kbps. However, some computer COM ports
are limited to 115.2 kbps. If you want to use your DIV AT/A at its maximum speed, install a
“fast COM port” card (UART 16650 based).
