Request local compression:
Setting this parameter to “Yes” causes the unit to request the use of VJ Header Compression,
which compresses TCP/IP headers to about 3 bytes rather than the standard 40 bytes. It is
gener ally only used to improve efficiency on slow speed links.
Request local PFC:
Setting this parameter to “Yes” causes the unit to request PFC (Protocol Field Compression),
which compresses PPP protocol fields from 2 to 1 bytes.
Request remote ACFC:
Setting this parameter to “Yes” causes the unit to get the remote to request ACFC (Address
Con trol Field Compression). When negotiated, the address/control fields are removed from the
start of the PPP header.
Request IPCP remote address option:
Set this parameter if it is required that the remote system have an address supplied. An attempt
to negotiate an IP address from the IP address pool will be made. Generally, this parameter is
set to “Yes” for incoming connections, and “No” for outgoing connections.
Request remote PAP authentication:
Set this parameter if it is required that the unit authenticate itself with the remote system using
PAP. If this parameter is set, the connection will fail if authentication is not successful. Generally,
this parameter should be set to “No”.
Request remote CHAP authentication:
Set this parameter to “Yes” if it is required that the unit authenticate itself with the remote
system using CHAP. If this parameter is set, the connection will fail if authentication is not suc-
cessful. Generally, this parameter should be set to “Yes” for outgoing connections and “No” for
incoming connections.
Request remote compression:
Setting this parameter to “Yes” causes the unit to get the remote to request the use of VJ com-
pression.
Request remote PFC:
Setting this parameter to “Yes” causes the unit to get the remote to request Protocol Field
Compression.
LCP echo request interval (s):
Setting this parameter to a non-zero value causes PPP to issue Link Control Protocol (LCP)
Echo Request packets to the remote peer at the specified intervals. This would be used to keep
a link active, for example when using GPRS.
Reset link after this many failed LCP echo requests:
When this parameter is set to a value greater than 0, the unit will terminate this PPP connec-
tion after there has been no response to this many consecutive LCP echo requests. When set
to 0 the unit will not terminate the PPP connection.
PING request interval (s):
If this parameter is set to a non-zero value the unit will automatically generate a “ping” (ICMP
echo request) to the address specified by the PING IP address parameter at the interval speci-
fied (auto ping). Setting the value to 0 disables the auto-ping facility. This parameter in conjunc-
tion with PING IP address and No PING response out of service delay can be used to configure
the unit to use a back-up interface automatically should there be a problem with this interface.
