To support the D-packet service, your ISDN network and
financial institution must be equipped with a D-packet
handler. To convert the protocol used by the transaction
equipment to the X.25 protocol, your ISDN network must also
be equipped with an integrated X.25 PAD.
X.25 PAD works with the following versions of X.25: Datapac
32011, CCITT, T3POS, ITT and API. The ISDN service
package you order must include D-packet service, for
example, Package P in the U.S. or Microlink™ with
D-channel in Canada.
Your service provider supplies a Terminal Endpoint Identifier
(TEI) and a DN to support D-packet service. The TEI is a
number between 00 and 63 in the U.S. In Canada, the default
range is 21-63. Your service provider may also supply you
with a DN to program your D-packet device. The DN for
D-packet service becomes part of the dialing string used by the
D-packet to call the packet handler.
POSTA for ISDN BRI
When you configure D-channel packet service, you are
specifying the transmission path between an ISDN loop on the
network side of the ICS and the ISDN loop on the telephone
side. The telephone side loop is the loop used by the point-of-
sale terminal adapter. The service is turned on and configured
using the network loop programming found under
Hardware
.
Use NT loop for BRI-U2 and BRI-U4 cards and S or T loop
for BRI-ST cards.
To set up D-packet service:
• go to the programming settings for the network loop under
Hardware
. (S, T, or NT loop)
• select the S loop or LT loop used by the POSTA
