Switch Manufacturer, e.g. AT&T, Seimens, Northern
Telecom.
•
ISDN ‘flavor,’ e.g., National ISDN or Custom Point-to-Point.
Please note that the TA101 terminal adapter will not work
with AT&T Custom Point-to-Multipoint nor will it work
with AT&T National ISDN software revision 5E9.1.
•
Service Provider Identification Numbers (SPID numbers).
National ISDN
always
requires SPID numbers, some locations
using Custom Point-to-Point
may
not require SPID numbers.
If SPID numbers are required, most areas use two, but some
implementations require only one (are you confused yet?)
Switch Type (North America and Germany Only)
It is necessary to tell the TA101 what type of switch protocol is being
used at the Telco central office. The ISDN service provider will give
this information to you. You only need to set the switch type once for
each TA since the switch governs both. Use the menu branch:
<TA101><Setup><Sw Type>
then select the appropriate switch type. The
CSW
command is used for
setting the switch type from a terminal.
In North America, four switch types are available:
•
5E6
is used for AT&T
Custom Point-to-Point
ISDN version 5E6 or
earlier. This selection is
not
used for AT&T National ISDN,
regardless of version number.
•
5E8
is used for AT&T
Custom Point-to Point
ISDN version 5E8 or
later. This selection is
not
used for AT&T National ISDN, regardless
of version number.
•
NTI
is used when the switch is a Northern Telecom DMS-100 switch
•
NI1
is used for all other National-ISDN-1 implementations,
including AT&T
.
German users have three choices: DSS1, 1TR6 and AUTO (AUTO will
not work if a PBX is used). Contact CCS-Europe for information on
which to use in your area.
