»» PPP Profile/PPP
The Express 6100/6120 supports the IETF standards for the Point-to-
Point Protocol. The PPP state machine running in the Express 6100/
6120 can be fine-tuned to support many applications that can be em-
ployed. The configurable items under this menu can be changed from
their default values for special cases.
PPP/VJ Compression
Write security: 3; Read security: 5
When this item is set to On , the Express 6100/6120 will perform TCP/
IP header compression known as Van Jacobson compression to the
PPP peer. Normally, this is not necessary over ISDN connections and
can be set to
Off (def) to disable it.
PPP/Max Config
Write security: 3; Read security: 5
This value is the number of unanswered configuration-requests that
should be transmitted before giving up on a call. The possible values
are 5, 10 (def), 15 and 20.
PPP/Max Timer
Write security: 3; Read security: 5
This value is the number of seconds to wait between unanswered con-
figuration-requests. The possible values are 1 sec, 2 secs (def), 3 secs, 5
secs and 10 secs.
PPP/Max Failure
Write security: 3; Read security: 5
Due to the nature of PPP, configuration options may not be agreed
upon between two PPP peers. This value is the number of configura-
tion-naks that should occur before an option is configuration-rejected.
This allows a connection to succeed that might otherwise fail. The pos-
sible values are 5 (def), 10, 15 and 20.
