DTE Port 2
This chapter describes how to set the TA128 into Two-DTE Port
and One Analog Port mode in which two users can use the TA128
simultaneously to place two independent calls to access the
Internet. The two-DTE-port feature is also ideal for Service
Providers in that two users can be serviced concurrently through
two COM ports, one TA128, and one ISDN BRI line.
Selection of the Two DTE Port Mode
By default, one DTE port and two POTS ports of the TA128 are
operable. But more often than not, since there are two B-channels
for your ISDN line, two users may want to share the TA128 to
access the Internet simultaneously. To make use of the second
DTE port, please set bit 0 of the S125 via DTE port 1.
ATS125.0=0 One DTE port and two POTS port mode (default).
ATS125.0=1 Two DTE ports and one POTS port mode.
Select the mode using the following procedures:
1. AT&Wn to save the configuration as a user profile n, where
n=0,1,2, or 3.
2. ATZn to select the said user profile n as the power-on default
settings.
3. Turn off the TA128 for a while and then turn it on again.

NOTE
: Once the two-DTE-port mode is selected, the POTS port marked
“
Phone 2” is disabled, i.e. it can neither be used to place a call
nor to answer a call. The POTS port marked “Phone 1” is
operable as usual.
