then select the appropriate switch type, either National or AT&T
Custom. Both the TA201 and TA301 are compatible with AT&T Custom
Point-to-Multipoint ISDN service. The
CCC
command is used for
selecting the country and the
CSW
command is used for setting the
switch type from a terminal.
Service Provider ID (SPID) Number
For
most
areas in North America, the TA must be told the SPID number
of the
calling
ISDN line, that is, the line to which the
RoadRunner
is
connected. The ISDN service provider in your area provides this
number.
It is important to remember that every time the
RoadRunner
is moved, or whenever there is a change in the ISDN line, or even
area code changes, the SPID and ID number, switch type and
possibly other parameters for the TA setup must be updated.
You
can store up to 20 ISDN SPID location configurations for later recall.
To set the SPID number using the keypad, go down the branch
<TA
x
01><Setup><N. America><SPID>
selecting the desired ‘B’ channel, and enter the SPID number. Please
note also, that each TA supports 2 basic rate ISDN ‘B’ channels, so if
your service provider gave you two SPID numbers you must enter both
of them, one for each ‘B’ channel. Use the
CSI
command to set the
SPID number from a terminal.
Identification (ID) Number
If you are required to use two SPID numbers, than you must use ID
numbers. For the TA201 and 301, the ID number is just the 7 digit
ISDN line number connected to the
RoadRunner
. Use the
<TA
x
01><Setup><N. America><ID>
branch, and set the ID’s for both ‘B’ channels from the keypad. Use the
CLD
command from a terminal.
The TA201 and TA301 use a 7-digit ID number for North American
operation.
LLC
For North American operation the LLC must be set to ON. This lets the TA
accept incoming calls at both 56 and 64 kb/s rates. Use the branch:
<TA
x
01><Setup><N. America><LLC>
