Port Connections 2-3
Data Port The Data Port provides connection to the customer equipment. Pinouts for the
backplane connector and both high-speed port interfaces are listed in Table 2-4.
Default settings route all available DS0s to the DTE port.
FCC rules require that interconnecting cables carrying high-speed data be shielded
appropriately to minimize radio frequency interference.
Supervisory
(SUPV) Port
The front panel supervisory (SUPV) port can serve
several functions. The unit’s terminal interface may
be accessed through this port (see Interface Start-up
on page 4-1) as well as the Call On Alarm feature on
page 4 -23. This port may be accessed through either
a direct connection or a dial-up connection using an
AT-command-set-compatible modem. The modem
should be optioned to ignore DTR, enable auto
answer, inhibit command echo, and return verbose
result codes. Serial bit rates can be set from 1200 bps
to 19200 bps. Refer to Table 2-5 for the pinout and to
Figure 2-2 for typical terminal/modem cable
diagrams.
If the unit is called and sent the break command before receiving the connect message, the
modem hangs up
