Protecting Communications Before Disaster Strikes
by Judy K. Bell, CEM
In
todays business environment, communications and information technology
equipment transcend all organizational boundaries. Plans to restore both need
to be an integral part of every organizations business recovery plans.
Some businesses believe they cannot afford the time to create recovery plans,
then find out later that they cannot continue to operate when disaster does
strike. Take the time now to build an effective communications plan.
Step 1: Inventory Existing Communications
Begin by
taking an inventory of all existing communications at each location, as well as
all facilities that link multiple locations together. If the information is
extensive, record it in a database that can be easily updated, listing
telephone or identification numbers and locations. Prepare a summary of the
quantities of each type of service currently in use. It should include all
centrex or PBX stations, single line business phones, datafax, essential
service lines, foreign exchange lines, public telephones, cellular, radio, and
faxes.
Record what
facilities are used to connect all locations. Identify the quantity and type
such as copper, fiber, microwave, or other transport elements.
Step 2: Determine Vulnerabilities
Every
business is susceptible to communications failures. Identifying what those
vulnerabilities are before they can affect service and reducing or eliminating
them should be a significant part of the planning process. There are four major
areas to check.
Structural - Evaluate how structurally sound the
building is which houses the communications equipment. Look for known hazards
that could damage the equipment such as water pipes located directly over
critical equipment. Check if there are any air-conditioning units mounted on
the roof. If so, make sure they are secured. If earthquakes are a major
concern, obtain a seismic evaluation of the building to determine its
likelihood to withstand damage. If there is a cable vault, check to make sure
it is clearly identified, and the right people know how to gain access to it if
necessary.
Evaluate all
the buildings in the immediate area. If they are owned by other businesses,
determine how their damage might affect your business. If there is a potential
risk, check with them to find out what their recovery plans are. Of particular
concern in today's environment are businesses that store large quantities of
hazardous materials. They have the potential of disrupting businesses in the
surrounding area if a spill occurs.
Equipment - If the communications equipment is
sitting on a raised floor, make sure both the floor and the equipment are
braced. Examine the cabinets, consoles, terminals and power equipment to make
sure all are properly secured. Survey the area surrounding the equipment to
make sure non-structural hazards such as bookcases and filing cabinets will not
topple onto the equipment, causing damage.
Some people
like to use the telephone closet as a place to store boxes of old records,
creating potential fire hazards. Others use it as a convenient place to sneak a
quick cigarette. Both situations are a disaster waiting to happen.
Lack of
adequate back-up power has proven be the true Achilles' heel of disaster plans.
Time and again businesses discover what should have been on uninterrupted power
supply (UPS) too late. Horror stories abound of total departments that could
not resume their functions because they were missing this vital resource.
Thoroughly
test the UPS. Determine what is hooked up to it, and how long the batteries
will last. If emergency generators are installed, check how often are they
tested, what they are hooked up to, and how long they will operate before
additional fuel is needed. Test emergency generators at least monthly with a
full load to ensure their continued operation at the time of an emergency. If
the fuel line depends on an electric pump, make sure it is hooked up to the
proper source.
If the
communications equipment requires temperature control or water cooling, check
how the heating, air conditioning, or water supply system operates, and whether
it is connected to emergency power.
Facilities and the Network -Determine how many
different routes the facilities take to get from one location to another. Make
sure there is more than one transport path for critical voice and data links.
If the business is served by an on-site PBX system, check to see what
capability it has to reroute calls to other locations. Equally important is the
ability to remotely access and reprogram the communications so that calls can
be terminated elsewhere if one location is damaged or inaccessible.
Both the
hardware and software elements of communications equipment have
vulnerabilities. Applications, operating systems, emulation and protocol
conversion software, network diagnostics and network management software as
well as network attributes and routing tables should all be backed-up regularly
and stored off-site.
Step 3: Maps
Draw a map
of each location plotting where the manholes, feeder routes, cable vault,
distributing frames or terminals, operator consoles, and PBX equipment are
located. Identify on the map the quantity of foreign exchange (FEX) lines,
direct inward dial (DID) trunks, data lines, PBX terminations, and tie lines.
Differentiate what terminates on equipment at that location versus what is
provided by the local telephone company central office or other vendor. Plot
where all essential service lines, public telephones, and any other vital
communications equipment is located.
Indicate
what equipment has back-up power, and how long it should last. If the business
will be relying on suppliers to augment fuel levels, list who they are and how
they can be reached. If only some electrical outlets are equipped with
uninterrupted power supply (UPS), make sure they are labeled.
Step 4: Identify Critical Communications
Needs
Every group
within the organization will have different requirements to transmit and
receive information following a disaster. Top executives will be making
critical business recovery decisions while employees are trying reach their
families. Plan for all of these needs by picking the right alternatives for
each to use.
First
determine who will be responsible for ensuring that communications will
function properly after a crisis. Next, decide who will coordinate the overall
business resumption planning, and form an interdepartmental committee with
representatives from all key groups.
Have
representatives identify what their own organization will need to communicate
during the disaster. Have them prioritize each of their critical functions so
that they identify in advance when they will need what. Make sure they consider
any additional requirements if a disaster occurs after-hours and people must be
contacted to report to work in advance of their normal shift.
Using the
communications inventories determine what existing equipment can be used to
meet each group's needs. At this point consideration should be given to the
kinds of disasters anticipated. If an unexpected event or a single location
crisis occurs, chances are the public telephone network will not be congested,
allowing normal communications to be used. However, if it is a regional
disaster, communications that are not dependent on the public telephone network
may need to be activated. Care should be taken in picking alternatives,
recognizing that no single solution will be completely free of
vulnerabilities.
Many
businesses plan to use radios. It is important to identify how many people will
be using each frequency. Also, radio transmission is a slower way of
communicating information, so the volume of information to be passed should be
closely evaluated. Consider using fax machines or e-mail to transmit damage
information instead of conveying everything via voice. If cellular phones are
to be used, be aware that cellular calls are on a separate network only when
completing cellular to cellular calls within the immediate area. As soon as
cellular phones are used to call to normal telephones, they are transiting the
public telephone network, which may be congested due to overloaded conditions.
If security of communications is an issue, both radio and cellular
transmissions may be subject to interception by outside parties.
Alternate
transport routes can also be used such as satellite and microwave services. In
the case of satellites, it is important to identify in advance which circuits
are on the satellite. For microwave, check with the vendor to find out how
quickly they will be able to respond if antennae shift out of adjustment. With
both alternatives, check ahead for other users on the same system, making sure
there will be enough capacity to handle all requirements. In many cases,
alternate communications may not be immediately available, but they can be
relied on a few hours after the event. It is better to know that in the
planning stages so other arrangements can be made.
Step 5: Request Additional Funding
After
evaluating the needs of all groups, identify if there will be any shortage or
mismatch of equipment, and develop the best solutions. Remember that following
a disaster there will be immediate requirements for communications equipment to
perform functions such as rescue and damage assessment. As time progresses and
those needs are met, that equipment can be redeployed for other uses. Careful
allocation of equipment based on time of need can reduce the amount of
equipment required.
If funding
is required, submit a budget request clearly stating what both the costs and
the benefits will be. Make sure the equipment actually gets installed and is
tested regularly so it will be ready for use.
Step 6: Document the Plans
Assemble all
of the communications information into a concise, easy-to-use format. Include
information for each location depicting exactly which communications groups
will be using. For example, emergency response team members may be
strategically positioned with radios near first aid and triage areas. Security
may use a separate frequency on the same radio system, and all response
personnel may have a mutual frequency to relay information to an emergency
operations center. Identify who will be on which channels, and where they will
be located.
In the case
of departments and key executives, each plan should identify which
communications they will be using.
Step 7: Prepare Checklists
Determine
which communications equipment will need to be tested for damage immediately
following the disaster. Prepare a checklist that is easy to follow spelling out
precisely what tests are to be performed. Have someone totally unfamiliar with
the equipment walk through the instructions on the checklist to make sure it is
correctly written. Appoint an alternate for back-up, and train the alternate on
all tests. If vendors are required to perform the diagnostics, contact them in
advance to discuss how quickly they will be able to respond.
Step 8: Perform Periodic Tests
Schedule
regular exercises that will incorporate all communications plans. Pay
particular attention to what may need to be changed because information flows
become congested or ineffective. Revise your plans after each test. Regularly
review all of the information to update personnel moves and other changes that
occur.
