To order the ISDN service from the telephone company for
the 3C882 ISDN modem:
1 Call the telephone company and ask for the ISDN
representative.
2 Tell the representative that you would like to place an
order for ISDN service for a 3ComImpact IQ External ISDN
modem.
3 Request that your line be provisioned according to
Bellcore capability package S1, the recommended ISDN
Ordering Code for use with your 3C882 ISDN modem.
IOC S1 provides circuit switched voice and data on both
B channels, allowing simultaneous voice and data on either
phone number, and may equip both ports with Additional
Call Offering (ACO). Note that you may need to specifically
request ACO, which allows for ISDN Call Waiting and
incoming DBA.
Some telephone companies may choose to implement ISDN
line provisioning uniquely. Therefore, some of the
Supplementary Voice features may not be available for use
with all telephone companies. Refer to "What Do I Need To
Support Supplementary Voice Features?" on page A-3 or
check with your telephone company for more information.
4 Specify the optional Supplementary Voice Features that
you would like to utilize on your ISDN line.
To take full advantage of the 3C882 ISDN modem, you need
to add Flexible Calling (FCO) features: 3-Way Calling (Call
Conference); Call Transfer, Hold, and Drop; Caller ID (which is
necessary to utilize the Call Logging feature); and the Call
Forwarding variable, which enables Call Forwarding. You may
also choose to order only those specific services that best fit
your needs. Note that there may be an additional charge
when adding each service to your ISDN line.
