Type of switch configuration used on your line.
You must
receive this information from your telephone company to prop-
erly configure the Netopia ISDN Modem.
The switch should be
one of the types suppor ted by the Netopia ISDN Modem:
■
AT&T 5ESS custom
■
Nor thern Telecom DMS-100 or Siemens EWSD
■

Directory numbers and SPID (service profile identifier) num-
bers.
This information may be provided to you at a later time,
after your line has been set up. There may be one or two direc-
tor y numbers, and one or two SPIDs. If the switch on your line
is an AT&T 5ESS custom point-to-point, you will receive no
SPIDs. It’s ver y impor tant that you record this information accu-
rately.
Note:
Regardless of the number of director y numbers and
SPIDs you receive, your line should be configured to allow the
Netopia ISDN Modem to use both B channels at once.
5.
Circuit ID number.
Your line has a unique physical address
called a circuit ID. You should obtain this number from your tele-
phone company and record it on the worksheet. The circuit
number can be useful for locating your line and its associated
circuit in case of a problem.
6.
Long-distance company to be used on your ISDN line.
When
the Netopia ISDN Modem makes long distance calls on your
ISDN line, you will be billed by a long distance telephone com-
pany. Make sure that you have the long distance company of
your choice.
