COMMUNICATION FROM THE ACS TO THE DISPATCH CENTER
8-5.1
Most alarm signals are usually transmitted from the ACS to the Dispatch
Center.

COMMUNICATION FROM THE DISPATCH CENTER TO THE ACS
8-6.1
Some projects require or are designed such that door unlock signals can be
manually generated from the Dispatch Center. In those cases a door open signal is an
output from a device in the Dispatch Center to the ACS.

BANDWIDTH ANALYSIS
8-7.1
A study should be made of the bandwidth communication requirements for
each subsystem through the DTM to the Dispatch Center. Typically, the CCTV system
will have the highest requirement, but there will be data communications normally in
the range of kilo-bytes-per-second (kbps) for the ACS system and IDS systems. The
DTM may make use of the base Information Technology systems. If base fiber optic is
used, a good design detail is a fiber schedule showing which fibers on which cables are
dedicated to the DTM or other systems. Plan on one fiber pair for ACS communication
one fiber transmit and one receive. Similarly, plan on one fiber pair for required IDS
communications. CCTV typically only requires one fiber per camera. For PTZ cameras,
one wavelength on the fiber can be used for the video signal and another wavelength
on the same fiber can be used for the PTZ control signals. Refer to Figure 8-1 for a
sample illustration.

Coordinate with the base communications officer (information technology) or
for Base Level Information Infrastructure and Defense Information Infrastructure.

Design Guidance on IT System Coordination. Fiber optic cables typically
come in multiples of twelve strands, with 12-strand and 24-strand fiber optic cable being
very common. While there are no technical limitations on combining ESS with other
