I. Introduction
The Communications Assistance for Law Enforcement
Act of 1994 (CALEA) requires telecommunications common carriers
to ensure that their introduction of new technologies and services
does not interfere with the execution of law enforcement wiretaps
and other electronic surveillance. The Omnibus Consolidated Appropriations
Act for Fiscal Year 1997 (Pub. L. 104-208) established a Telecommunications
Carrier Compliance Fund (TCCF) for making payments to telecommunications
carriers, equipment manufacturers and providers of telecommunications
support services to modify their equipment and services to comply
with CALEA.
In response to concerns about implementation
of CALEA, the FY 1997 Appropriations Act required the FBI to submit
to Congress a CALEA implementation plan before funds could be
expended from the TCCF. The Act required that the plan include:
1) an explanation of law enforcement capability requirements;
2) specific surveillance capacity requirements; 3) a prioritized
list of equipment, facilities and services to be modified by carriers
to comply with CALEA; and 4) a projected reimbursement plan that
estimates per year costs.
CALEA Background.
The telecommunications industry has always cooperated, and is
committed to continuing to cooperate, with lawful and authorized
law enforcement electronic surveillance activity. As technology
has developed, electronic surveillance has become easier in some
respects, and the widespread use of communications technology
means that electronic surveillance can collect far more personal
information. Every year in recent years, even as new technologies
and services have been introduced, the amount of law enforcement
surveillance has increased, with industry providing assistance
to more wiretaps today than ever before, leading to more successful
law enforcement investigations and convictions.
Nonetheless, law enforcement has been concerned
that technological developments make law enforcement interception
more difficult in some respects. These difficulties are often
encompassed by the term "digital telephony," although
digital transmission itself is not really the problem. In hearings
in 1994, the FBI cited a variety of concerns, some of which existed
in analog systems: problems intercepting calls rerouted through
call forwarding, or the inability to identify the destination
of a call when a customer used a speed dialing feature.
Following hearings and consultation with
industry and privacy groups, Congress responded to these technological
developments by enacting CALEA (Pub. L. 103-414). CALEA required
telephone companies to ensure that new technologies (and some
old technologies) did not impede law enforcement interception
of communications.
CALEA was intended to preserve the status
quo in terms of law enforcement surveillance, without expanding
government capabilities. CALEA requires telephone companies to
design (and in some cases retrofit) their networks to ensure that
law enforcement agencies can carry out electronic surveillance
on advanced digital equipment and services. It imposes on telecommunications
carriers four minimum functional requirements, pertaining to (1)
the interception of call content; (2) the interception of reasonably
available call-identifying information; (3) the delivery to law
enforcement of intercepted call content and call-identifying information;
and (4) the security of intercept operations and the privacy and
security of communications not authorized to be intercepted. CALEA
requires manufacturers to make available, "on a reasonably
timely basis and at a reasonable charge," such features or
modifications as are necessary to permit carriers to comply with
CALEA capability and capacity requirements.
CALEA was never intended to serve as an
FBI surveillance "wish list." Both House and Senate
reports on CALEA stressed that the requirements should be narrowly
interpreted. However, law enforcement has attempted to broadly interpret the requirements of CALEA to mandate a nationwide surveillance capability in excess of traditional interception practices. The most notable and most troubling illustration of this is the FBI effort to use CALEA, in contravention of explicit assurances during the legislative drafting process, to require wireless phone companies to have a location tracking capability built into their systems for law enforcement purposes. The FBI is also claiming, for example, that CALEA mandates interception of certain conference calls after the targeted facility has been dropped from the conversation. Additionally, the FBI has argued that CALEA requires the configuration and delivery of a signaling channel that includes detailed message notifications about both the targeted facility and facilities not identified in the surveillance order.
Capability Must Be Determined by Industry
Standards, Not FBI Decrees. The
CALEA assistance requirements are phrased in general terms. To
develop the details for implementation of these requirements,
Congress intentionally rejected a delegation of authority to the
FBI. Instead, Congress deferred to carriers and equipment manufacturers
to interpret the requirements through the industry standards process.
Congress expected that this approach would temper law enforcement
demands with considerations of cost, competitiveness, innovation,
security and privacy. Congress gave to the FCC, not the FBI, the
power to judge whether any industry standard was deficient.
Now, the FBI appears to be trying to rewrite
the legislative record, trying to assume to itself the authority
that Congress rejected. Instead of supporting efforts by industry
to implement promptly a narrow set of requirements -- requirements
that would preserve the status quo and be largely achievable within
currently deployed systems -- the FBI is claiming that CALEA mandates
as a national minimum the installation of many advanced and automated
capabilities that go far beyond traditional wiretap capabilities.
The FBI's repeated demands for "gold plated" capabilities
that far exceed CALEA requirements has significantly retarded
development of an industry standard and delayed compliance.
II. Capability Information
A. The FBI's Wish List Is Not Mandated
by CALEA
In April 1996, the FBI began to circulate
the Electronic Surveillance Interface Document (ESI), describing
the delivery format the FBI wanted carriers to use in delivering
intercepted communications to law enforcement. In addition, the
ESI described the features, capabilities, and types of information
that law enforcement would like to receive as part of an interception.
These included location information, feature status messages,
and service status messages.
However, the ESI should not be viewed as
an embodiment of CALEA requirements or as a "safe harbor"
for compliance as stated by the FBI. Nothing in CALEA or in the
legislative history suggests that Congress intended to mandate
the type of design-specific, intrusive, and potentially expensive
capabilities that are described in the ESI. Congress stressed
that the CALEA requirements were to be narrowly interpreted, and
were intended to preserve the status quo. A number of elements
of the ESI represent proposed enhancements of surveillance capability.
Law enforcement can take advantage of these enhancements if they
arise in the course of service development, but CALEA does not
mandate that they be made available universally.
The implementation plan is misleading, therefore,
in treating the ESI as an embodiment of CALEA's assistance capability
requirements. It is not. The ESI contains several features that
exceed CALEA requirements. These features were rejected by the
industry standards groups for inclusion in the standard intended
to implement CALEA. The rejected features also would violate customer
privacy and present immense technical problems for carriers.
B. Congress Intended to Allow Industry
to Set Standards Section 107 of CALEA specifically authorizes industry, not law enforcement, to develop compliance standards.
When the ESI was first circulated, it was
described by the FBI as a "safe harbor" standard, compliance
with which would satisfy CALEA. After widespread criticism of
this as a usurpation of industry's explicit role under Section
107 of CALEA, the FBI recharacterized the ESI as merely a contribution
to the industry standards process, which was then well underway.
In the implementation plan, the ESI is once again treated by the
FBI as a de facto safe harbor standard. The FBI, as the implementation plan indicates, has had extensive input into the standards setting process (190 meetings with industry to express law enforcement's views). The FBI's approach to implementation has gone well beyond the consultative role contemplated by CALEA for law enforcement, and in part explains why it has been so difficult to develop standards. Even when viewed as law enforcement's contribution to the industry standards process, the ESI was disruptive. For months while the ESI was in preparation, law enforcement simply took no position or deferred comment on standards issues. When the ESI was delivered, it had little relationship to the standard document under discussion by the industry group. The ESI was not intended to be integrated into the standard nor to address existing standard elements; rather, it was intended to be a take it or leave it alternative. The standards body nonetheless took up the ESI, preparing side by side comparisons with the draft standards document in an effort to accommodate as much of the government's requirements as possible. All of this effort caused significant delay in completing the standard.
Now that the standards process has produced
a proposed standard, it is contrary to the intent of CALEA for
the FBI to continue its insistence that the standard is deficient
because it did not incorporate all of the FBI's recommendations.
The nature of the standards process is that no party has all of
its contributions accepted. In this case, while industry was respectful
of what law enforcement wanted, it was bound by what CALEA mandated,
and many of the FBI's proposals went beyond CALEA.
Sections 103 and 107 of CALEA allow for
multiple industry or even individual
carrier technical solutions to implement law enforcement
requirements. The FBI is expressly prohibited
(Section 103) from dictating or requiring system design features.
The FBI's insistence on the ESI as essentially the only acceptable
means for compliance, as well as its attempt to draw industry
into "cooperative agreements" to implement the ESI,
represent exactly what the FBI is prohibited from accomplishing
under CALEA--the dictating of specific designs and systems configurations.
It has led to the delays in implementing the law.
In addition to going beyond CALEA, the ESI
cannot substitute for an industry standard because (1) it is not
"adopted by an industry association or standard-setting organization,"
and (2) it is not "publicly available." (The ESI is
marked "U.S. GOVERNMENT RESTRICTED - FOR OFFICIAL USE ONLY.")
Unlike an industry standard, the ESI cannot be challenged under
CALEA by privacy groups, industry or any other person. It is not
subject to the public accountability that Congress deemed essential
to CALEA compliance.
FBI Claim:
The FBI states that the Electronic Surveillance Interface (ESI)
"would satisfy law enforcement's prospective electronic surveillance
needs and would constitute an acceptable means of achieving compliance
with the delivery capability requirements under Section 103 of
CALEA." (Page 13.)
C. Industry Has Acted Expeditiously to
Develop a CALEA Standard
Industry has proceeded expeditiously and
in good faith to develop a standard for CALEA compliance. The
standards process was begun in the Spring of 1995. By October
1995, the proposed standard, known as PN-3580, was 170 pages in
length. The FBI began limited circulation of the ESI in April
1996, and did not "issue" it until June 24, 1996, almost
15 months after the industry process was begun.
The drafting of the proposed industry standard
is finished, and the proposal, now officially referred to as SP
(Standards Proposal)-3580, is currently undergoing a "balloting"
process, through May 12, under the auspices of the Telecommunications
Industry Association. It is also undergoing Public Review at the
American National Standards Institute through June 24, 1997.
The proposed industry standard is attached.
D. FBI Attacks on the Proposed Industry
Standard are Unjustified and are Delaying CALEA Implementation
The proposed standard has many of the same
features as the ESI. However, it does not include some features
that the FBI recommended, because such capabilities had no basis
in CALEA.
FBI Claim:
The FBI argues that the proposed industry standard SP-3580 is
deficient for not including certain functionality proposed in
the ESI. The implication is that the FBI may challenge the standard
as deficient unless the ESI is accepted.
FBI Claim:
The FBI suggests that the ESI has wide-spread support.
FBI Claim:
The FBI complains that the SP-3580 standards document is "open
ended" and lacks "technical specificity" as compared
to the ESI.
FBI Claim:
The Implementation Plan states that the industry developed standard,
SP-3580, "does not include all of the functionality required
to satisfy evidentiary needs dictated by law and the courts."
p. 11
III. Capacity Information
Under CALEA, telecommunications carriers
are required to install, upon government request and at government
expense, sufficient capacity to accommodate multiple simultaneous
law enforcement intercepts. On January 14, 1997, the FBI released
its Second Capacity Notice. (The first Capacity Notice, issued
in October 1995, was roundly criticized and was withdrawn. It
took over a year for the FBI to issue a new notice.) The Second
Notice sets forth projected numbers of wireline and wireless surveillances,
based on an analysis of a historical baseline of electronic surveillance
activity.
The implementation plan fails to mention
that the Second Notice, like the first, has been subject to widespread
criticism by both industry and privacy groups. It also fails to
mention that while CALEA envisioned final notice of capacity requirements
within one year following enactment, with industry compliance
three years after that, the final notice is not yet available.
This fact further demonstrates the level of complexity and the
resulting delay inherent in CALEA implementation.
When it adopted CALEA, Congress assumed
that capacity requirements could be finalized by October 25, 1995.
The FBI's failure in finalizing capacity numbers has impeded development
of hardware and software for CALEA compliance.
IV. Prioritization of Equipment, Facilities
and Services Modifications
CALEA anticipated a prioritization by law
enforcement of how and where to allocate resources, and the appropriations
act directed the FBI to provide a "prioritized list of carrier
equipment, facilities, and services" to be modified. The
plan fails to make this prioritization.
Indeed, far from prioritizing, it is clear
from the implementation plan that the FBI's goal is to obtain
implementation of its entire "wish list," as reflected
in the ESI. The FBI is requiring carriers to price-out its capability
wish list, and clearly intends to use the TCCF to pay equipment
manufacturers to build to the ESI, regardless of what CALEA requires.
The FBI is using its reimbursement powers to ensure that its desired
standard is implemented.
This raises an interesting question: Is
it proper for the FBI to use CALEA funds to pay for capabilities
not mandated under CALEA? In a good faith effort to be cooperative, companies are taking steps to cost out SP-3580. But the FBI is using the pricing study to promote the ESI. The industry has reluctantly agreed to cost out elements of the ESI, but this is only diverting resources and causing further delays.
The FBI fails to acknowledge the significant
industry concerns regarding its cooperative agreement process.
Contrary to the FBI's assertions, no carriers are close to signing
a cooperative agreement because these agreements impose onerous
and inappropriate obligations on carriers. Moreover, by insisting
that the industry cost-out the additional capabilities on its
"wish list" the FBI is consuming valuable resources
that could be used to speed development of equipment complying
with PN-3580.
Prioritization is essential for several
reasons. CALEA contemplated prioritization to force law enforcement
to identify in a publicly accountable manner where and how it
intends to focus its activities. Limited funding authorized by
CALEA further would cause law enforcement to choose the most cost
effective, highest priority capabilities and capacities. CALEA
did not intend to provide law enforcement with a blank check for
ubiquitous or "gold plated" surveillance capabilities
or capacities, nor did it intend to allow law enforcement to shift
costs of retrofitting network technology from a government responsibility
to industry. Moreover, without prioritization, industry is led
to believe that there is no intent to reimburse carriers for their
reasonable costs of compliance and/or that they will need to modify
all equipment, services, and facilities.
Finally, the need for prioritization is
even more evident in the case of small companies that may have
little or no history of electronic surveillance activity of any
type. These companies also more commonly may deploy the kinds
of network equipment and technology not identified in the FBI's
list of the 19 most common switching platforms. These small telephone
companies are especially affected by a lack of prioritization.
They need specific guidance on what compliance requirements are
expected of them and how and whether they will be reimbursed.
V. Projected Reimbursement Plan:
The FBI implementation plan makes no real
disclosure regarding costs to implement CALEA. It is remarkable
that the FBI failed to distinguish between how much it will spend
for capacity and how much it will spend for capability. The plan
simply spreads the $500 million evenly over 5 years and tells
Congress that the FBI will be more specific next year when it
knows more. The projected reimbursement plan is based on government
cost estimates by "subject matter experts." (page 27).
What are the government estimates? Who are the subject matter
experts and how did they arrive at their estimates? Any government
cost estimates are suspect at best because the standard is not
complete, and manufacturers have only preliminary information
about systems engineering and cost analysis requirements. Virtually
no implementation cost information has been obtained from the
carriers by the FBI. Moreover, if the FBI insists that the ESI
is its bottom line, then the extent to which the ESI exceeds industry
standards will only add to the costs of compliance. The plan fails
to address either the costs of SP-3580 (the industry standard
currently released for balloting) or the excess costs of
those items in the ESI which are not found
in SP-3580.
CALEA permits switch manufacturers to make
features available at a "reasonable
charge" and for carriers to be reimbursed for "all reasonable
costs" of their compliance. But the plan reinforces the FBI's
intent to treat CALEA like a government procurement, requiring
"cooperative agreements" based on government procurement
procedures. This approach has caused unnecessary delays and implementation
complications. CALEA does not require "cooperative agreements"
or any other particular form of agreement as the only means of
compliance or of seeking reimbursement. CALEA is not a government
procurement program. It is more reasonable and cost-effective
to structure reimbursement as simple claims for reimbursement
-- as CALEA provides -- rather than as procurements.
The Cost Recovery Rules developed by the
FBI, by incorrectly contemplating a government procurement process,
would impose significant burdens on telecommunications carriers.
In order to provide the details that are specified by the FBI
in regard to cost estimates and billing information, the carriers
would have to modify existing financial systems or develop entirely
new systems. Although these concerns were expressed by numerous
parties during the review process, the FBI chose to largely ignore
them.
The Final Cost Recovery Rules are an example
of the FBI's attempt to hide the
true cost of CALEA compliance. By narrowly defining recoverable
costs under CALEA, they shift the cost of compliance to carriers.
At the same time, the FBI inserted a definition in the final rules
that would render obsolete an entire generation of switches and
eliminate the secondary market in used switches so depended upon
by smaller carriers. The FBI defined "deployed or installed"
to mean operational in a carrier's network. Thus if a carrier
bought a switch the day before CALEA was enacted and intended
to deploy it the following year, the FBI has determined that it
is non-compliant and that it is not subject to reimbursement for
any upgrade to make it compliant. In short, the FBI shifted the
entire cost of the transition period to carriers. A rulemaking
on what constitutes a "significant upgrade" and "major
modification" is pending and we have no doubt that the FBI
will give these terms the widest definitions as well so as to
continue to shift the cost of compliance to carriers.
A specific unresolved issue is the reimbursement
of carriers for retrofitting the increasing universe of current
equipment that was installed, deployed or upgraded after January
1, 1995. CALEA has a presumption that such equipment would be
CALEA-compliant. As a safety-valve, Congress created a procedure
for any company to petition the FCC for a determination that compliance
was not reasonably achievable for equipment installed, deployed
or upgraded after 1/1/95. Given the delay in resolving disputes
over the interpretation of CALEA, it has been impossible for companies
to install CALEA-compliant equipment, yet they have had to move
forward with system upgrades. The FBI plan assumes that every
switching platform currently in use needs to be modified to comply
with CALEA. Yet carriers have, of necessity, continued to upgrade
and expand their systems by installing this apparently non-compliant
equipment. How will the FBI treat this equipment? Will the FBI
reimburse carriers for retrofitting this equipment once "solutions"
are available? The implementation plan does not answer these questions.
CALEA makes clear that Congress intended
to reimburse carriers for their reasonable costs of retrofitting
equipment during the time that CALEA technology is being developed
and made available to carriers. Existing network equipment that
could not have incorporated CALEA technology (because it didn't
exist) should be deemed in compliance until the government reimburses
the carrier to bring it into compliance with CALEA technology,
and if necessary, the legislation should be amended to make this
clear.
CALEA did not intend to shift costs from
government to industry for retrofitting networks with CALEA technology.
Therefore, until such time that CALEA technology is available,
or unless the carrier is reimbursed to retrofit network facilities
to bring them into compliance, Congress should ensure that equipment
that has been deployed by telecommunications carriers after January
1, 1995 and before such time as CALEA technology is reasonably
available, must be considered in compliance with CALEA.
Finally, it should be noted that carriers
continue to cooperate with law enforcement in providing assistance
to their efforts to conduct legally authorized electronic surveillance.
There are no known cases that USTA or CTIA member companies are
aware of where carriers have been unable to provide such surveillance
assistance for law enforcement. Indeed, there is more electronic
surveillance activity now than ever before -- using existing telecommunications
network facilities and technology.
Implementation Delays and Compliance
Dates:
The implementation plan admits that technology
to comply with CALEA does not yet exist. The plan basically admits
that CALEA-compliant technology will not be available even by
the October 1998 deadline. The plan says that systems engineering
takes 6 months and will not begin until the second quarter of
1997 (assuming the balloting process reveals no requirements to
modify the industry standard). Engineering development takes another
12 months. Then production, deployment and testing must follow,
although the FBI plan puts no estimate on how long those steps
will take. Given even the optimistic time line advanced by the
FBI's plan, the FBI admits that installation of upgrades to the
embedded base will not be ready to begin until 1999. The schedule
should be no different for new deployments.
While CALEA provides for a compliance deadline
extension by petition to the FCC, this waiver process would itself
be time-consuming and could potentially overwhelm the FCC, which
might have to review each waiver for each facility or service
at issue. Industry needs greater assurance when investing in and
deploying network technology. Thus, the October, 1998, compliance
date should be moved to a time that reflects when CALEA technology
is reasonably available.
Recommendations
The committees should hold hearings to examine
the FBI's CALEA implementation plan for the purpose of (i) ensuring
that CALEA funds are not expended on requiring the ubiquitous
installation of surveillance enhancements that are outside the
scope of CALEA but are limited to achieving compliance with the
features reflected in the industry standard; (ii) to determine
whether the compliance dates of January 1, 1995 and October 25,
1998 are still valid, reasonable, and achievable, given the unanticipated
delays that have occurred in the implementation process; and (iii)
to address the other concerns raised herein.
Notes:
1
The FBI plan also refers to "SR-3529,"
a document funded by six of the Regional Bell Operating Companies
through Bellcore, for the purpose of conducting pricing estimates
on various surveillance features. This document exists in several
versions, including an "M" ("minimum") version,
which reflects the features contained in SP-3580, and a "P"
("premium") version that includes many of the features
found in the FBI's ESI that were not included in SP-3580. When
the FBI refers favorably to SR-3529, it is presumably referring
to the "P" version. All versions of the document specifically
state that none of the features or functions identified therein
indicate conformity with, or acceptance of, CALEA safe harbor
standards. The FBI's implementation plan fails to mention these
caveats. |
