Opinion by
Jacobs, J.,The appellees, Robert Helms and Kenneth Spacil, were charged with conspiracy to fraudulently obtain telecommunications service and conspiracy to possess and possession of instruments or devices used to achieve theft of communications service.1 Both appellees moved to suppress evidence obtained by security personnel of the Bell Telephone Company of Pennsylvania contending that such evidence was obtained in violation of the Pennsylvania anti-wiretapping statute.2 The lower court granted the suppression motions and the Commonwealth appealed.3
The facts reveal that an employee of Bell Telephone Company, while running a routine office check on telephone trunk lines, discovered the presence of unusual multifrequency sounds on one of the lines. On each of the next several days he also heard these unusual tones. The employee was aware that these sounds were not consistent with sounds generated by any equipment which the Bell System was using in the area, and were not consistent with any malfunction which he had been trained to anticipate in the equipment. He therefore suspected *541that a trespasser was illegally using the equipment, and notified Bell security personnel.
The Bell security officer assigned to the case, acting with the assistance of the employee who had discovered the sounds, observed the multifrequency tones and the accompanying voice transmission. He identified the tones as emanating from a “blue box” device, an illegal electronic device which permits the user to electronically bypass telephone company billing equipment and to seize access to worldwide telecommunications equipment without charge. The security officer immediately ordered a trace of the line being used, which revealed that the call was placed from the address of one of the appellees, Kenneth Spacil.
Bell Telephone’s security division then began an intensive monitoring campaign through which it positively identified 47 probable possessors and users of the blue box device. The security officer testified that the purpose of the investigation was to identify the parties who were in possession of and using the devices and to identify the methods employed. Commencing on the first evening of the investigation, August 23, 1971, the company made tape recordings of the conversations which were originated by means of the blue box. The security officer, Beam, admitted that the communications equipment was in perfect working condition and that he employed the taping procedure solely to determine who was defrauding the company and how. Beam testified that he continued to monitor and tape, over a one-month period between August 23 and September 23, 1971, conversations originating from the Spacil residence and three other residences as they were identified. He stated that some of the conversations monitored lasted as long as an hour and a half and reiterated, “ [a] gain, these tapes were in the attempt for intelligence ...” Beam testified that the telephone tap on the Spacil telephone was in operation 24 hours a day until it was removed in late September. *542He stated that although the tap was not monitored for all of that time it would have been possible for anyone entering the room in which the monitor was located to listen to the phone. Although Beam testified that he was certain that no calls other than trespass calls were monitored, he acknowledged on cross-examination: “Q: You had to identify it as a trespass call by listening to the substance of it? A: That’s right. And when we were in, I mean, this is what basically what [sic] I would do.”
Beam also admitted that incoming calls not made by a blue box were monitored in some instances. Beam stated that although his purpose in the selective taping was to gain intelligence as to the methods employed and by whom, the tapes often included “general conversation” between the two parties, some of whom were not under investigation.
On September 24, 1971, Bell security personnel notified the District Attorney’s office of the results of its investigation and the appellees were subsequently arrested and charged with the offenses indicated.
The appellees asserted in their suppression motions below that these acts by the telephone company employees were in violation of the Pennsylvania anti-wiretap statute4 and that, therefore, all such evidence and the fruits5 thereof were inadmissible in the prosecution against them. The Pennsylvania statute upon which they rely states in pertinent part:
“No person shall intercept a communication by telephone or telegraph without permission of the parties to such communication. ... No person shall divulge or use the contents or purport of a communication intercepted in violation of this act. . . . The *543term "divulge’ includes divulgence ... in a judicial, administrative, legislative or other proceeding. Except as proof in a suit or prosecution for a violation of this act, no evidence obtained as a result of an unlawful interception shall be admissible in any such proceeding.” (Emphasis added).6
The Commonwealth, however, and the Bell Telephone Company of Pennsylvania in an amicus brief, assert that the acts of the telephone company personnel were specifically excluded from the prohibitions of the Act by virtue of its last sentence, which states:
“Nothing in this act shall be interpreted to apply to acts done by personnel of any telephone or telegraph carrier in the performance of their duties in connection with the construction, maintenance or operation of a telephone or telegraph system.”7
The resolution of this case thus turns upon the meaning and breadth of the statutory exclusion which pertains to telephone company personnel, most particularly it turns upon the meaning of the phrase “in connection with the construction, maintenance or operation.” The Commonwealth argues that the phrase was intended to and should be construed to encompass the investigative procedures employed by the phone company in the instant case. It asserts that these procedures were necessary to maintain the integrity of the system by preventing fraud and to protect the continued operation of the system by assuring that all proper charges would be billed.
The issues before us thus simply defined are whether the Legislature in enacting the statutory exclusion intended to permit the communications carrier to engage in monitoring and recording for the purposes for which it *544was used in this case;8 and if so, whether the methods employed broke the connection between the acts done and the “construction, maintenance or operation” of the system.
No Pennsylvania court has yet been presented with the interpretation of this statutory exclusion from the proscriptions of the statute, and we have found no cases from other jurisdictions in which courts have interpreted a similar exclusion.9 It is true, as noted by the dissent, that the Pennsylvania statute imposes criminal penalties for its violation and must, therefore, be strictly construed.10 Accepting such a construction, we are still unable to find that the exclusionary phrase “in connection with the construction, maintenance or operation” is “clear and free from all ambiguity.”11 When the words of a statute are not explicit the Statutory Construction Act permits us to consider in ascertaining the intent of *545the Legislature, among other matters, the occasion and necessity for the statute, the mischief to be remedied, and the object to be obtained.12
The problem of electronic surveillance poses many troublesome questions both for legislatures and courts. Our Legislature, as were others, was aware of the dangers inherent in the use of electronic surveillance and of the necessity of acting to prevent its proliferation. “The tremendous scientific and technological developments that have taken place in the last century have made possible the widespread use and abuse of electronic surveillance techniques. As a result of these developments, privacy of communication is seriously jeopardized . . . ”13 “In a democratic society privacy of communication is essential if citizens are to think and act creatively and constructively . . . External restraints, of which electronic surveillance is but one possibility, are thus repugnant to citizens of such a society.”14 In considering the occasion and necessity for an anti-wiretapping statute and the mischief to be remedied thereby, the Legislature “was well aware of the grave threat to the privacy of every American that is posed by modern techniques of electronic surveillance.” United States v. King, 478 F.2d 494, 503 (9th Cir. 1973), cert. denied, 414 U.S. 846 (1974). In interpreting the statute our Supreme Court noted that the Legislature “determined as a matter of state public policy that the right of any caller to the privacy of his conversation is of greater societal value than the interest served by permitting eavesdropping or wiretapping.” Commonwealth v. Papszycki, 442 Pa. 234, 239, 275 A.2d 28, 30 (1971).
*546It is clear, however, that the Legislature did foresee the possibility that some conversation interception would be necessary by telephone company personnel “in the performance of their duties in connection with the construction, maintenance or operation”15 of the system. We are inclined to accept the premise that the Legislature did not intend to leave the communications carrier without defense to the hazards of electronic theft. The operation of the telephone system must include the ability to insure that charges for telephone service are properly billed, and it cannot be doubted that widespread use of electronic devices would defraud the carrier of lawful revenues and would seriously undermine the ability of the company to render quality service to its customers. We therefore conclude that a communications carrier, consistent with the exclusion in the Pennsylvania statute, may monitor illegal phone calls in order to verify the presence and detect the source of electronic theft.
A conclusion that the telecommunications carrier may make a defensive effort to protect the integrity of its services, however, does not mean that the methods employed by the phone company in this case fall within the strictures of that exception. Activities lawfully begun in connection with the operation of the system may be escalated and extended into a sphere of activity which is no longer connected with the “operation” of the telephone system. The “object to be obtained”16 by the anti-wiretap statute, the rigid protection of the right to privacy, must not be obscured in our interpretation of this statute. The Legislature clearly limited the immunity granted to communications carriers to those activities done “in connection with” the construction, maintenance or operation of the system. To read this limitation out of the statute would be to ignore the express dictates of the *547statute and to act contrary to its overall objectives.17
A review of the facts of several recent cases demonstrates that it is possible for the telephone carrier to protect its system with a minimum of intrusion into the integrity of conversations. For instance, in People v. Garber, 275 Cal. App. 2d 119, 80 Cal. Rptr. 214 (1969), cert. denied, 402 U.S. 981 (1971), the telephone company established by use of a computer printout that over 2000 illegal calls were made from a given phone during a seven month period. The company then installed a monitoring system which was in operation for some 27 days. The tape recorder was activated only by the multifrequency tones of the blue box device, thus assuring that only illegal calls were recorded. During the continuance of the monitoring system there were only 28 hours of actual monitoring and only 65 minutes of blue box calls were actually overheard and recorded. By contrast, in the case at bar no computer evidence was introduced, the tape recorder was not selectively electronically activated, and the tap was left open 24 hours a day.
In United States v. Shah, 371 F. Supp. 1170 (W.D.Pa. 1974), the court after examining the facts held that the phone company acted reasonably in monitoring blue box calls. The phone company had made an analysis of computer print-outs and installed a recording device which was only activated by illegal tones. The recorder once activated only recorded the first 60 seconds of any conversation and then automatically shut off. The phone company explained that the sole purpose in the monitoring was to establish the identity of the person using the phone and thus the 60 seconds were thought to be sufficient to accomplish this objective. In that case no incoming calls were monitored and the total duration of the monitoring campaign was seven days. In United *548States v. DeLeeuw, 368 F. Supp. 426 (E. D. Wis. 1974), a multifrequency tone-activated recording system, which again recorded only the initial minute of any illegal call, was terminated after three days when the phone company established the identity of the caller.
In the case before us several salient facts are readily apparent. The recording system was not tone-activated; therefore, as Beam testified, the only means of identifying the call as illegal was by listening to its substance. Thus, legitimate calls were monitored and recorded. To argue that the monitoring and recording of legitimate phone conversations can be done in connection with the construction, maintenance or operation of the telephone system stretches the fabric of this Court’s imagination. Secondly, no attempt was made to minimize the intrusion. This is, of course, completely contrary to the clear intent and mandate of the Pennsylvania anti-wiretapping statute. In this case some of the conversations monitored and taped were an hour and a half in duration and the tap was operating 24 hours a day. This activity extends far beyond any exclusion the phone company may need in order to continue effective and efficient service. The monitoring in this case continued long after the location, identity and method of the trespasser were clearly established. In our view such extensive monitoring and recording were unreasonable, unnecessary and unjustifiable. “To sanction such practices on the part of the telephone company would tend to emasculate the protection of privacy [the anti-wiretap statute] intended to protect.” Bubis v. United States, 384 F.2d 643, 648 (9th Cir. 1967).
The Pennsylvania anti-wiretap statute applicable to this case unequivocally forbids the admission of evidence obtained as a result of an unlawful interception.18 Because the monitoring done by the telephone company in this case far exceeded the bounds of the exclusion pro*549vided by the Legislature it was done in violation of the act and the evidence was properly suppressed by the lower court. We recognize that our decision today permits the appellees to dodge the sword of justice, but we deem it more important that the telephone company should not resort to unreasonable and unnecessary practices. The Statutory Construction Act permits us to consider in ascertaining the intent of the Legislature, the consequences of a particular interpretation.19 If we were to interpret as lawful the activities of the phone company in this case, we would be permitting the company to listen to and record any and all private conversations between citizens on the assertion that a search for possible electronic theft is “connected” to the operation of the system. We must presume that the Legislature did not intend such an unreasonable result.20
We cannot condone and we will not accept the acts of the telephone company in this case. It is our charge to jealously protect the individual right to privacy which is a hallmark of a free society. Commonwealth v. Murray, 423 Pa. 37, 223 A.2d 102 (1966). No system of justice in such a society can accept or tolerate unreasonable and unbounded intrusions, whether by government officials or by private individuals, upon that basic and fundamental right.
