Configuring PPP
130 Perle 833IS User Guide
Address
When checked, the 833IS will attempt to negotiate address compression during
connection. This reduces the size of the PPP header. For address compression to be
used, both the 833IS and the client must negotiate this option.
IP Header
When checked, the 833IS will attempt to negotiate IP header compression.
IPX Header
When checked, the 833IS will attempt to negotiate IPX header compression.
STAC (Analog Call)
When checked, the 833IS will attempt to negotiate STAC compression (software
compression) for all analog calls.
STAC (Digital Call)
When checked, the 833IS will attempt to negotiate STAC compression (software
compression) for all digital calls.
Enable Multilink PPP
By default, Multilink PPP is enabled for all dial in clients. To disable

PPP. On connect, the 833IS will check with the client to see if it wishes to
use Multilink PPP. Some clients (for example, MacPPP) do not support this
negotiation and will fail to connect.
Async Control
Click this button to access the Async Control screen.
This is an advanced feature of PPP that lets you select any control characters that are
not allowed to be transmitted on the network. Whenever a selected control character
appears in the data stream, it is preceded by an escape sequence and changed into
non-control characters. The destination then converts these characters back to the
original value.
With an ISDN BRI connection to the phone network, all control characters may be
transmitted by the 833IS. On the other hand, the client may be using network
equipment that requires some control characters to be masked off. The client should
