Card Number Display only.
X.25 card address A calling address appended to outgoing calls. Used for
programmatic access to PAD devices. Also used for network loopback
test. For most network applications, this is the same as the address
used for X.25 system-to-system communications.
Note that with certain networks (such as Transpac, in France) the
called address is removed from incoming call packets and the calling
address is added to outgoing call packets by the network. For these
networks, enter only the subaddress in this field, not the full X.25
address.
PVCs Low and high values for permanent virtual circuits as listed on your
X.25 subscription.
One-way incoming SVCs Low and high values for one-way incoming switched virtual
circuits as listed on your X.25 subscription.
Two-way SVCs Low and high values for two-way (incoming and outgoing) switched
virtual circuits as listed on your X.25 subscription.
One-way outgoing SVCs Low and high values for one-way outgoing switched virtual
circuits as listed on your X.25 subscription.

configure PAD support, the subscribed and configured packet size must
be 128, 256, or 512 bytes.
Window size Window size for incoming and outgoing data as listed on your X.25
