DXP Correspondence ManualInstalling The DXPExpansion Cabinet Power SupplyThe installation of the expansion cabinet power supply is virtually’
identical to that of the main cabinet power supply. One critical
difference between the two, however, is that there is an AC and DC
connection from the expansion cabinet’s power supply to the main
cabinet’s power supply (for more information on the expansion
cabinet power supply, see 
lMI66-086). Both the power cord and the
DC connection from the expansion cabinet...

Connecting A
Battery BackupThe DXP works with the Comdial BBLDX. Should the AC power
fail, this main battery backup provides a minimum of one hour of
system operation on a 70% loaded system. To guarantee an hour with
an expansion cabinet, you need two battery backups. Comdial ‘has
created a formula whereby you can determine the battery backup time
for your system based on your number of lines and stations (see
IMI89-074). You can install an additional battery backup, or another
manufacturer’s battery...

dedicated line slots; note that Unlike the station board designations,
the line slots are numbered from right to left. Each line board also has
a pre-power jack that allows a technician to service the board while
the system still has AC power on. The connection of the line board
depends upon the type of line board (for information on the wiring of
line boards, see 
IMI66-085)....

Connecting The
Stations1  Station connections, like line connections, are typically through66M-xx connector blocks. The station boards, like many of the line
~  boards, are also connected through 
25pair male amphenol connectors.
While the station boards have protection against shorts, it’s better to
~  punch down the wiring with the power off.
Both IST devices and digital stations are two-wire connections, but
you should skip space on the IST block to avoid crosstalk. With digital
signals, crosstalk...

Testing The
StationsPower up the DXP and take a voltage measurement across each signal
pair on the type-66 station block. The appropriate voltage
measurements are also shown on charts in 
IMI66-085.To test the stations, plug in the digital station and check to see that the
LCD appears (if applicable). Once the LCD comes up, perform a
station self-test:

Connecting An
External Paging
DeviceYou can connect a paging device either to the paging port on the
Services board or to a line port. The line port can be used to couple a
station’s voice path to an external paging device. Any station with the
line appearance can use the PA system by selecting the line; IST
stations can use the amplifier by dialing a line-group access code.
When the paging device is connected to a line port, users can speak
through or dial DTMF tones or pulses to the external...

Connecting A
ModemThe DXP has its own proprietary modem, product number DXMDM,
so installation is simple. You can use a non-proprietary modem, but
using the modem designed for the DXP is a good idea. The modem
installs next to the power supply in the main cabinet. All that’s
involved in the hardware connection is attaching the mounting screw
to the card cage. The top jack on the modem is for the line cord, and
the bottom jack is for the serial data...
