Modem (J85501F1
L-AE)
The Modem option permits communication over the public network
analog lines at baud rates of up to 19200. This option is necessary for
Call Out on Alarm and to enable the Data Switch option to access the
public network.
Included with the Modem option are the following:
• BJL Modem Board
• Modem Port Cable Interface Card
1. Mount the Modem Port Cable Interface Card on backplane
Connector P101 and secure with the mounting screw provided on
the card. Refer to Figure 2-2 for backplane mounting locations.
This Interface board contains 2 RJ11 telephone line jacks, J111 &
J112. Connect J112 to the incoming analog phone line and use
J111 if desired to extend this line on to another phone or device.
(J111 & J112 are connected in parallel internally. The use of
another phone or device on the same line as Galaxy may cause a
“No Dial Tone Detected” warning should Galaxy attempt to call
out while the line is in use.)
2. Set BJH or BJJ SW203-3 and SW203-4 as desired to define the
type of access to be allowed via the Modem port. See Table 3-D.
3. The BJL Modem board can only be located in Option slot 1 in the
Intelligent side of the Galaxy card cage. See Figure 3-1. Refer to
Section 3, Circuit Pack Addition/Removal/Replacement, for
information on adding the BJL pack into its assigned slot.
