The important question in this case is whether the appellant should be allowed to use a machine called “Telfast” for completing long distance calls to points in Arkansas served by Southwestern Bell Telephone Company. A minor question relates to an injunction.
The appellant, Allied Telephone Company (hereinafter called “Allied”), is an Arkansas corporation owning and operating telephone exchanges in the cities of Sheridan and Fordyce, as well as in several other cities in Arkansas. Southwestern Bell Telephone Company (hereinafter called “Southwestern”) is a corporation (being a subsidiary or affiliate of American Telephone and Telegraph Company) operating telephone exchanges and long distance lines in Arkansas and several other states. The Bell system of American Telephone and Telegraph Company (of which Southwestern is a part) is nation-wide, whereas Allied is one of several so-called independent companies operating in Arkansas.
In order that the subscribers of the independent telephone companies may complete long distance calls to points on the Southwestern system throughout Arkansas,1 and in order that Southwestern subscribers in *494other Arkansas cities may complete long distance calls to subscribers served by independent companies, there exists a so-called standard “Traffic Agreement” between Southwestern and the various independent companies specifying how long distance calls will be handled over the long distance lines of Southwestern throughout the State. Thus long distance calls are available from any point in the State to any telephone exchange having-such Traffic Agreement with Southwestern. The present Traffic Agreement between Allied and Southwestern was signed on July 21, 1961, and was for one year and then automatically renewable until notice of termination should be given by, either party. Two of the provisions in the Traffic Agreement are:
“V. TOLL OPERATING. The toll operating-(tick-ting and timing) required hereunder shall be performed as may be agreed upon from time to time between the parties.
“VI. METHODS AND PRACTICES. With respect to all matters covered by this Agreement, each company will adopt and comply Avith standard Bell System operating methods and practices and Avill observe the rules and regulations of the lawfully established tariffs. Each company -will, upon request, furnish to the other such information relating- to the interchanged business covered herein as may reasonably be required.”
There are at least three methods now in use for making and completing long distance calls:
(1) Call the operator2 at a local exchange and place the long distance call to the place, number, and/or person desired; and the operator handles interchange and communications, and the person placing the call has only to wait until his desired number or person is reached. This is called the “Operator Method.”
*495(2) Use the method of “Distance Direct Dialing,” whereby the person making a station to station call dials an area code, exchange number, and the number of the telephone at the destination desired. This is called the “DDD Method.”
(3) Use the method known as “Person to Person Called Special” whereby the person making the long distance call may dial direct to the desired city but have an operator come on the line to control completion of the call and the billing of the charges either to the person called or to a credit card or to a third party number. This method is called “PPCS.”
The foregoing three methods are now in operation in various exchanges; but the problem involved in this litigation arises because of a fourth method which Mr. Hugh E. Wilbourn, President of Allied, has invented and desires to use at the Allied telephone exchange in Sheridan, Arkansas. This fourth method for handling of long distance calls is called “Telephone Fully Automatic Switching and Ticketing,” and is herein referred to as “Telfast.” Below we copy the description of “Telfast” as contained in Allied’s brief in this Court:
‘ ‘ Tape recording equipment is added to the existing automatic ticketing machines of a PPCS system. Station to station prepaid calls work like DDD and PPCS. The difference comes in sending other types of toll calls. To operate the equipment, the subscriber dials three digits: the first activates the machine, the second indicates the type of call that he wishes to make, and the third designates which station on a party line is making the call. Then the subscriber dials the area code (if the call is to another state), followed by seven digits of the desired number. Both the calling and called number are recorded in a computer, and the call is stored in the machine. At this point, the subscriber is connected with the tape recorder and a periodic beep tone commences. The tape recording tells the caller what type of call he has dialed and gives him instructions (e.g. for a credit card call, the recording might state, ‘when you hear the bell, give *496your credit card number’). After a certain period of time, up to twenty (20) seconds, the machine rings the called number. When a party answers at the called number, the subscriber, in a person to person call, asks for the desired person, or in a collect call, asks if the party will accept the charges. During this period the tape recorder is running to make sure that the correct party has reached the phone or that the charges will be accepted. When the desired party is reached, or charges are accepted, the calling party dials the digit 2 which disconnects the tape recorder (including the beep tone), and the call is timed and ticketed automatically. If, for any reason, a subscriber does not wish to use the Telfast equipment, e.g. if he wants time and charges, he may dial the digit ‘O’, get the operator, and proceed to complete his call with operator assistance.”
There is no Telfast machine now in use in any telephone exchange in the United States., Mr. Wilbourn’s invention of Telfast has been patented during the course of this litigation and the Kellogg Division of the International Telephone Telegraph Company is ready to manufacture and install a Telfast machine in Allied’s exchange in Sheridan, Arkansas.
With the above background matters, we come to the present litigation. On June 14, 1963, Southwestern filed before the Arkansas Public Service Commission3 a complaint against Allied regarding Telfast. The complaint alleged the traffic agreement between Allied and Southwestern; that Southwestern had been notified of Allied’s intention to install a Telfast machine in the Sheridan exchange; “that the use of such equipment would create numerous problems and have much a detrimental effect on long distance telephone service that Southwestern could not agree to Allied’s proposal.” The complaint also alleged:
“The use of the aforesaid ticketing equipment in the mailing of long distance calls will conflict with Bell *497System standard practices and, therefore, violate the parties’ Traffic Agreement. It will also cause damage, expense and financial loss to Southwestern, will adversely affect the quality of toll service furnished jointly by Allied and Southwestern, will lead to toll service abuses and will result in dissatisfaction, confusion and complaints on the part of Southwestern’s customers and other telephone users in the State of Arkansas. The use of such equipment would unreasonably impair the ability of Southwestern and Allied to furnish reasonably safe, adequate and sufficient service to the telephone users in Arkansas and would be contrary to the public interest. ’ ’
The complaint detailed a number of results — all claimed to be detrimental to the long distance service— that it was claimed would flow from the use of Telfast by Allied in its Sheridan exchange; and the prayer of the complaint was that the Commission order Allied to refrain from the installation or use of Telfast. Allied resisted Southwestern’s complaint, insisting that Allied had a managerial right to use the new and improved Telfast in its exchange; prayed that Southwestern’s complaint be dismissed, and said:
“Allied is desirous of mailing available to its subscribers of all classes the best possible service which becomes available through technological advances in the science of telephony. Allied admits that one feature of the system being installed in Sheridan is technologically new, and like all new equipment can only be tested out in practice, as have been all of the technological advancements made in telephony; . . . ” Also Allied said:
“Allied proposes that a hearing on the merits of this controversy be delayed for six (6) months, during which time the. Sheridan System can be given a trial run. During this period of time all dialings invoking the unique features of the system will be monitored by a human operator in Fordyce so that no possible fault in the system will result in harm to the subscribers or *498to Southwestern. Allied considers that the facts which will become available through actual experience are necessary for a proper determination of all issues of customer service, and that actual experience in the operation will resolve all controversy with Southwestern with regard thereto.”
Southwestern resisted the six months abeyance plea of Allied; the Arkansas Telephone Association and the City of Sheridan intervened on behalf of Allied; and the Commission proceeded to a full hearing on all issues. Various witnesses testified and a record of more than 700 pages is before us. On December 12, 1963, the Commission entered its order refusing to hold the case in abeyance for six months, ordering Allied to refrain from installing the Telfast machine in its Sheridan exchange for use in any calls over Southwestern’s long distance lines, but permitting Allied to use the Telfast machine on its own lines.4
There was a Majority Opinion delivered by two of the Commissioners and a Dissenting Opinion by one Commissioner; and the Opinions demonstrate the care with which the Commission considered this cause. Prom the order of the Commission adverse to it, Allied proceeded in due channels through the Circuit Court, and the cause is now here before us and Allied has made three points, to-wit:
“I. The Commission exceeded its authority in prohibiting installation of adequate service equipment because of ‘degradation.’
“II. The Commission exceeded its authority in prohibiting installation of Telfast because of an alleged breach of contract.
‘ ‘ III. The order is erroneous because it is arbitrary and capricious.”
We will'use our own topic headings in disposing of the issues.
*499I. Use Of Telfast On Long Distance Galls Over The Southwestern Lines.
The Commission found:
“The Allied proposal would degrade the quality of long distance service, would breach the contract between Bell and Allied; and would, therefore, be adverse to the public interest.”
Based on the above finding the Commission ordered:
“That Allied be, and it is hereby, ordered to cease and desist from installing the proposed system at Sheridan for the purpose of connecting it to Bell’s facilities.”
It is well to state again the extent of our review in a case like this one. In Barnes v. Ark. Public Service Comm., 235 Ark. 683, 362 S. W. 2d 1, Mr. Justice Bohlinger quoted from an earlier case:
“ ‘It is well settled by our decisions that the Commission is clothed with broad legislative and administrative powers and that a review of its findings and order by either the circuit court or this court, on appeal, is considerably limited in its extent. Ark. Stats., See. 73-233 (d) provides that such review shall not be extended further than to determine whether the Commission has regularly pursued its authority, including a determination of whether the order under review violated any right of the complainant under the U. S. or State Constitutions. However this does not mean that the courts cannot inquire beyond mere formality when other provisions of the statute are considered along with Sec. 73-233, supra. In this connection we have repeatedly held that if the Commission’s order is supported by substantial evidence, free from fraud, and not arbitrary, it is the duty of courts to permit it to stand, even though the courts might disagree with the wisdom of the order. Department of Public Utilities v. Ark.-La. Gas Co., 200 Ark. 983, 142 S. W. 2d 213; City of Fort Smith v. Southwestern Bell Telephone Co., 220 Ark. 70, 247 S. W. 2d 474; Arkansas Power & Light Co. v. Arkansas Public Service Commission, 226 Ark. 225, 289 S. W. 2d 668.’ ”
*500Witnesses for Southwestern testified that the use of ■ Telfast by Allied at its Sheridan exchange would violate the provisions in the Traffic Agreement, as heretofore copied; would reduce revenue to Southwestern because of the holding of circuits in attempting to complete calls; and would degrade the quality of long distance service in the confusion and slowing of service. This latter was explained by these features:
(a) The person placing the call would be required to dial an increased number of digits;
(b) the presence of the “beep tone” would be an innovation;
(c) the person placing the call would directly inquire if the person called would accept the collect call, and this ' might be in language much longer than the regular operator would use; and
(d) then a new digit would be dialed or the line would be automatically disconnected after an interval.5
A reference back to the description- of the Telfast Method clearly shows that the foregoing factors are present. Also it was shown that the telephone industry has spent large amounts of money and considerable time to educate the telephone using public as to Distance Direct Dialing; that PPCS has not yet gone into full service ; and that larger amounts of money and much more time would be required before the telephone using public could efficiently use the Telfast system, which is as great a departure from the DDD as that method was from the Operator Method. Even the PPCS is not yet in general use, and Telfast contains additional factors not found *501in PPCS. Furthermore, witnesses testified that the use of Telfast by Allied in its Sheridan exchange would necessitate the expenditure by Southwestern of several thousand dollars in its Little Eock exchange. There were other matters in evidence, but we have detailed enough to show that the Commission’s findings meet the tests set by our cases.
Allied says that the finding that Telfast would “degrade” long distance service is not the correct test. The applicable statute (Ark. Stat. Ann. § 73-218 [Eepl. 1957]) gives the Public Service Commission the power to “Detemine the reasonable, safe, adequate, sufficient service to be observed, furnished, enforced, or employed by any public utility, and to fix the same by its order, rule, or regulation.” The record before us shows that the present long distance service, without Telfast, complies with the requirements of the quoted statute. When the Commission found that the use of Telfast to complete long distance calls over Southwestern’s lines would “degrade” the service, such was tantamount to a finding that the use of Telfast for such long distance calls would result in service that would be less than “reasonable, safe, adequate, sufficient,” because the word “degrade” means (according to Webster) “to lower from a superior to an inferior level,” or “to lower or impair in respect to some physical property,” or “to damage.”
We conclude that the order of the Public Service Commission — that Allied cease and desist from installing Telfast System for the purpose of connecting with Southwestern’s long distance lines — is sustained by the. Commission’s findings, which are likewise sustained by the evidence, and should be affirmed.
II. Refusal To Allow The Six Months Trial- Period Sought By Allied. Allied moved that the Commission temporarily postpone any hearing and decision and allow Allied a period of six months to install the Telfast machine in the Sheridan exchange for use on all long distance calls over Southwestern lines. Allied claimed that the Commission would be able to determine from *502actual experience the effect of Telfast, and offered to indemnify Southwestern for any loss or expense caused by such six months trial period if the Commission, on final hearing, found against Telfast.
The Commission postponed decision on this six months test period request until the final hearing in this cause, and then disallowed such trial period on Southwestern’s long distance calls. The order of the Commission on this point is:
‘ ‘ That the motion of Allied to hold these proceedings in abeyance until the completion of a trial of the equipment and procedure, during a controlled test period, be, and it is hereby, overruled.”
Allied insists that the Commission allowed Allied to use the Telfast machine on long distance calls on its own lines, thereby — -as Allied claims- — finding that Tel-fast was not “degrading” Allied’s efficiency. Why then —insists Allied — should Telfast not be tried on Southwestern’s system? The answer seems clear to us: one of the point made by Southwestern against the immediate use of Telfast on Southwestern’s long distance lines was the amount of money and time that would be required to educate the telephone using public as to the new procedure required for Telfast. If Allied wants to undertake this educational effort among its own subscribers in its limited territory, it is free to do so; but the Commission found that it was not feasible to have this done all over the State at this time. The City of Sheridan intervened to support Allied, so evidently the City of Sheridan feels that the educational program on Telfast will not be too difficult for calls in that area; but just as “one swallow does not make the spring,” so one Tel-fast machine in Arkansas does not require Southwestern to undertake a six months educational campaign for long distance telephone calls originating in Sheridan.
Progress is sometimes made by small independents, rather than by large corporations, and-we sincerely hope that Telfast will prove to be a great forward advance in long distance telephone service. The mere fact that *503Telfast is something new that Southwestern had not installed and the like of which the Bell Laboratories have never been able to 'perfect, is no justification for the objection of Southwestern to the use of Telfast by Allied on its own lines; but the amount of educational campaign and advertising that Southwestern and other companies would have to conduct over their entire systems in Arkansas to explain the use of Telfast is a good reason for the action of the Commission in denying Allied’s request for a six months trial period. The order refusing the use of Telfast on Southwestern long distance calls is not res judicata. After Allied has used Telfast for a time for long distance calls on its own lines, and thereby demonstrated the efficiency of Telfast, Allied may see fit to ask the Commission for a new hearing as regards Telfast on Southwestern lines long distance calls. In such event, the entire issue will be tried anew without any plea of res judicata being available to Southwestern.
III. The Injunction To Prevent Allied From Rerouting Long Distance Calls. This issue is largely unrelated to the Telfast issue, but is in the same case. The Traffic Agreement signed by Allied - and Southwestern on July 21, 1961, and previously discussed, provided that' Allied’s Sheridan exchange would be interconnected with the Southwestern facilities at Sheridan and served by Southwestern’s Pine Bluff, Arkansas Toll Center. The complaint filed by Southwestern in this case alleged the foregoing Traffic Agreement and alleged that Allied was proposing to reroute all outgoing Sheridan long-distance calls through Allied’s Fordyce, Arkansas Toll Center, and proposed to use Southwestern’s Sheridan-Pine Bluff facilities for incoming traffic only. Southwestern prayed that Allied be enjoined from such rerouting of its outgoing long distance calls, and claimed that such rerouting would be a violation of the Traffic Agreement between Southwestern and Allied. The Commission made this order:
“That Allied be, and it is hereby, ordered to cease and desist from rerouting- Sheridan Long- Distance traffic through Fordyce, and it is further ordered to main*504tain the present routing of such traffic during the existence of the present traffic agreement between Allied and Bell.”
While this is a minor issue in the case, we nevertheless conclude that the Commission acted beyond its jurisdiction in enjoining Ailed from the breach of a contract on the broad terms as contained in the aforesaid copied order. Of course, if there had been a finding that such rerouting of calls would result in inadequate service to the telephone using public, then the Commission would have had jurisdiction, since, under Ark. Stat. Ann. § 73-218 (Repl. 1957), its duty is to see that service is adequate, etc. But there was no finding in this case that the mere rerouting of Sheridan long distance calls through Pordyce would result in any inadequate service ; and the Commission is not the proper forum to enjoin a .mere breach of contract.
In Asso. Mechanical Contractors v. Ark. La. Gas Co., 225 Ark. 424, 283 S. W. 2d 123, there was a proceeding-brought before the Arkansas Public Service Commission ■by the Associated Mechanical Contractors, seeking to enjoin and restrain Arkansas Louisiana Gas Company from selling and installing- air-conditioning- equipment in competition wth the Associated Mechanical Contractors. The Commission found that it had no jurisdiction in such a case, and we upheld the holding- of the Commission to that effect. The cited case is ruling here. The mere fact that Allied may be about to breach its contract with Southwestern does not give the Commission jurisdiction to issue an injunction in the absence of any factual finding (and there is none to that effect in this record) that such breach of the contract would impair the service to the public. Southwestern must seek its remedy in the proper judicial tribunal regarding breach of the contract, rather than before an administrative agency. So we reverse that part of the Commission’s order which enjoined Allied from rerouting Sheridan long distance traffic through Pordyce. To that extent only the order of the Commission was in error.
*505In all other respects the order of the Commission is affirmed.
