between the CCE and the dispatch consoles should be less than 2000 feet, unless modems
or optics are used for the data paths. Short Haul Modems (P/N 950-9222) are required
beyond 2000 feet and up to 1 mile. The VoIP Console Gateway (P/N 905-0265) is required
for distances longer than a mile.
The socket outlet for the AC input power shall be installed near the CCE and be easily
accessible. The socket outlet shall be installed by authorized personnel. Refer to the
electrical specification for power requirements.
Model 4048 Mounting
The Model 4048 CCE must be rack-mounted (see Figure 10 ).
The console interface cardcage (Part # 901-9462) is shipped with an extra top/bottom
cover (Part # 415-0110). The extra cover should be mounted on the bottom of the lowest
Channel Cardcage (Part # 950-9691), using the supplied mounting hardware (1 black 4-40
x ¼” screw and 6 standard 4-40 x ¼” screws). If the system has only one channel
cardcage, mount the cover on the bottom of the cardcage. If the system has two channel
cardcages, mount the cover on the bottom of the lower cardcage.
Each Channel Interface cardcage is shipped with a rear cover (part # 415-0119-1), which
is mounted on the back to connect adjoining cardcages. This cover provides chassis
ground between cardcages.
Power Supply
One or two Model 4048 power supply modules are installed at the top of the rack. For
power supply fault tolerance, two modules can be installed in a load sharing arrangement.
If either module fails, the remaining module powers the system avoiding interruptions.
CCE Console Cardcage
The Model 4048 CCE Console Cardcage, typically installed below the power supply
modules, contains 18 card slots. The first two slots accept the Model 4048 System Traffic
Card (STC). The STC manages communication between components of the CCE. Only
one STC is required for normal operation; a secondary STC is installed to serve as a
redundant backup if the primary STC fails. The remaining 16 slots accept the Model 4048
Console Interface Cards (CICs). The CIC cards interface the system to the console
positions. The CCE accommodates a maximum of 16 console positions. If a patch card is
used, it will occupy the right-most slot (slot 18). The CCE will then accommodate 15
console positions.
