Dual/Single Jack Operation
The Phonecell
®
SX5 may be operated in either dual-jack or single-jack mode. The factory
default is dual-jack mode.
Dual-Jack Operation
In dual-jack operation, for outgoing calls, the first jack to seize the line (go off-hook) will discon-
nect the other jack. The other jack will remain disconnected until the first jack goes back on-
hook. For incoming calls, voice calls will be routed to the phone voice jack and fax calls will be
routed to the fax jack.
Single-Jack Operation
The analog fax jack can be disabled leaving only the voice phone jack operational (single-jack
operation). In single-jack operation, voice calls can be placed and received normally if a tele-
phone is connected. If a fax is connected, incoming analog fax calls can be received normally,
but to place outbound fax calls using the voice jack, a bypass sequence must be used as a pre-
fix in the dialed telephone number. The analog fax jack will not generate dial tone nor ring signal
if it is disabled.
To Set A Single - Jack Option
The following key sequence is used to enable or disable fax jack operation in favor of single
jack operation (all telephone calls through phone jack):
#
*
63
*
<single jack> #
The single jack value is set to 0 for single fax jack operation; 1 for both voice and fax
jacks. If the single jack value is neither 0 nor 1, it is considered invalid. The factory
default is 1.
To Set In-Bound Fax Port Option
The following key sequence is used to enter the inbound fax port option:
# * 67 * <fax_port> #
The fax port value is set to 1 incoming fax calls to the fax port (dual port operation), or phone
port (single port operation), and 3 to send incoming fax calls to the DB - 9 PC port. If the fax
port value is neither 1 nor 3, it is considered invalid. The factory default is 1.
NOTE: If the single jack option above is set to single, all incoming analog calls will always go to
the phone port.
