Handling Analog Calls

Analog adapters enable you to connect analog devices (e.g.
telephone, fax, PBX, or modem) to an ISDN Basic Rate line. Any
conventional analog telephony equipment which supports DTMF
tone/pulse dialing can be plugged into any one of the two RJ-11
sockets (labeled phone 1 and phone 2) on the back of the TA128.
This chapter will outline the steps you need to take to place and
answer analog calls via your ISDN line.
The analog adapters use RJ-11 phone jacks. The pin assignment of
the jacks are shown in Chapter 18 .
German ZyXEL customers: The inner two pins of the RJ-11 are
used for the Tip and Ring (or a and b signals in Germany, the two
signals that connect to a telephone set). This is the standard pin
assignment, but some BZT-approved telephones use the outer two
pins for a and b. If this is the case, use the attached TAE adapter
which has a unique interface definition or use an RJ-11 cable that
connects the inner pins on one end and the outer pins on the other
end.
