Fields
You use this screen to configure X.25 level 3 and miscellaneous
parameters for the DTC/X.25 Network Access card being configured.
You must define the level 3 parameters for both X.25 system-to-system
and PAD connections.
DTC Name Display only.
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.
Maximum
number of PAD
connections Number of PAD connections that you will allow at any
given time through the card being configured. The
maximum number of connections that can be allowed
are: For DTC16 the maximum is 32, for DTC48 the
maximum is 256 and for DTC72MX the maximum is
156. Note that this number specifies the limit for all
PAD calls through this card, including both nailed and
non-nailed connections.
