First, a general comment ... you have run into a problem that cries out for resolution in many areas of the country. Without going into a long diatribe, local calling areas in many part of the country are laid out in somewhat arbitrary and discriminatory patterns ... patterns that may have made perfect sense 40 or 50 years ago, but no longer do. I could write paragraphs about this but for now I will just say that one common example is that folks living in major metropolitan areas can often call anywhere within a 25-50 mile radius (it varies by area), while folks living in rural areas of the same state may be lucky if they can call into the nearest town without incurring a toll charge. My opinion has always been that it would be much fairer to give everyone local calls within a certain radius (say 20-30 miles, like the folks in the big cities get [Chicago excepted, of course]), no matter where they live within a state. One of the strengths that competitive local dialtone providers will have is that they won't have to follow the exchange boundaries of existing telcos. But, I digress ... > Since she has no "office", we terminated her business phone line in > our residence.

Have you checked the local calling areas to see if there is another exchange that is a "free" call from both the exchange in which the RCF number is installed, and your residence? If so, you could set up the Remote Call Forwarding in THAT exchange, your customers in the neighboring town could still call you for free, and you'd lose the per-minute charge. I'm assuming you've checked out this possibility already, but on the other hand, I'm amazed at how many people don't ... they just don't think about going through a third exchange (the shortest distance between two points may be a straight line, but in telephony that's NOT necessarily the least expensive route!). > I recently discovered that one of my neighbors has "foreign exchange > service" in their residence.

I hate to sound like a broken record, but people should never, ever deal with "business office" personnel if you have a need that's the least bit unusual. The minute you realize that the person you're talking to either doesn't have a clue, or is being evasive, you need to ask to talk to a supervisor (and the supervisor's supervisor if necessary). The goal of the lowest level folks is often to answer your question (note I did NOT say "CORRECTLY answer your question) and get you off the line as quickly as possible. If you're REALLY getting the runaround, you might try saying to the supervisor that if you can't get a straight answer from the telco, you'll try forwarding your question via the Public Utilities Commission and see if THEY can get a straight answer, and request the supervisor's name so that you can put it in your letter in order to show that you did try to get the information through regular channels first. If you say something like that, the supervisor will generally kick you up to someone who can help you post haste ... but if not, a written request sent via the PUC will often get you ACCURATE information like nothing else will! Now, the sad fact is that in many areas untimed Foreign Exchange (FX) service is available only on a "grandfathered" basis ... that is, it's available only to existing customers, and then only as long as they remain at their current location. If they move, they lose it, or have to get the newer FX offering that charges a per-minute rate on both incoming and outgoing calls. There ARE ways around this, but you have to be pretty telecom-savvy and do a lot of digging. The first thing I'd check for is any intra-LATA toll calling plans that the telephone company doesn't want you to know about. The PUC may be able to help you find these, if they exist. For example, in Michigan, there is the Adjacent Exchange Toll Calling Plan (AETCP) that (for residential users only) provides UNLIMITED calling to all adjacent toll exchanges (those in your LATA only) for $15.00 per month. Since Michigan allows the unlimited option for residential lines only, it wouldn't help you much, but then you aren't in Michigan anyway. :-) My point, though, is that it's like pulling teeth to get many Michigan telcos to even tell you that the AETCP exists, and even if they do, they'll try to sell you on "Circle Calling" or some other MEASURED option instead. So you want to look for intra-LATA optional calling plans that are tariffed, but not widely advertised or promoted by the telcos. Failing that, let's go back to that FX line. Think about what it really is. It has (at least) two components: Provision of local dial tone (essentially a regular POTS line that could be terminated in the same exchange, if you had an office there, but isn't) and the line that extends your POTS line to another exchange (including any repeaters, amplifiers, etc.). If you let telco handle both components of this in a "bundled" offering (which is essentially what FX is), then they can hook up their meter (so to speak) and charge on a per-call basis. But now suppose that you order each component separately and YOU tie them together (preferably without telling telco, although as long as you're ordering tariffed services and not using them illegally, they really can't say much even if they find out). To give you an example: Suppose your wife works out a deal with one of her customers in the neighboring town ... preferably one that owns contiguous property that crosses the exchange boundary, if such exists. She gives the guy free annual immunizations for his horses or something like that, and he allows her to put some phone equipment in his basement (or even a dry part of his barn), and maybe erect a SMALL structure (a storage shed would probably do) on the other side of the property. If the property straddles an exchange boundary, you order a POTS line on each side of the boundary, (one terminating at the house and the other in the storage shed which would of course be on the other side of the boundary), and then you run a hunk of underground cable between the two, and use a WATS-extender type device (or even a simple two-line call forwarding device, if all you care about is incoming calls) to forward calls from one line to the other. If you can't get access to property straddling the exchange boundary (or if tariffs absolutely forbid having service from two different telcos on the same property, even if the property does straddle the boundary and even if the service would be in separate buildings), then your goal would be to get an UNmeasured line between your remote location (where your POTS line terminates in the adjacent town) and your office. There are several offerings that might be available: 1) A "dry" metallic pair, sometimes referred to as an "intercom" or "audio" circuit. You do NOT need a "conditioned" pair such as used for broadcast applications, but depending on the tariffs, that may be the only type of metallic circuit available. This would work only if the combined distance of your "dry" pair PLUS the loop serving your POTS line isn't too long to allow reliable operation (if is is, as I think it might be in your particular case, you might still be able to do it if you insert a "long loop extender" device into the loop). In this case, you'd simply cross-connect your POTS line to your metallic pair, stick a phone at the office, and keep your mouth shut about what you did! 2) An "Off-Premises Extension" (OPX) line. Strangely enough, in some areas you can get what is essentially an unmeasured FX line IF you also have a "real" phone in the serving exchange. In this case, the "real" phone is considered the primary line, and the line coming into your office would be considered an "Off-Premises Extension" of the first line. So, assuming you had a POTS line put into your customer's home in the neighboring exchange as suggested above, you would tell telco that you have opened an "office" in your customer's basement, and need an "Off-Premises Extension" of the phone line there that terminates in your real office (your home in this case). This is actually similar to what you'd be doing in number 1) above, except that telco would be more responsible for maintaining the quality of the line (also, the mileage charges MAY be different because in one case they'd be calculated from your customer's home to your office, while in the other case they'd probably be calculated from the telephone exchange building to your office). 3). A PBX Off-Premises Extension. Some telcos have gotten wise to the fact that a regular OPX line can be used as an FX line, so they have filed tariffs that say that even if there IS a phone in the serving exchange, if the OPX is in a distant exchange the ALL calls on the line (no matter which extension they originate from/are answered by) must be billed on a per-minute basis, similar to FX lines. This is a hard sell to the PUC's (since the phone located in the serving exchange might indeed be the primary business location), so tariffs differ from state to state. But there is another type of Off-Premises Extension, and that is an extension hanging off of a PBX. In this case telco gives you what is essentially the equivalent of a bare pair of wires and you are expected to connect one end to a PBX (which supplies dialtone) and the other end to a telephone instrument. Of course, if the PBX allows you to dial "9" and access an outside trunk at the remote location, and if the PBX just happens to be set to "night answer" and all incoming calls ring directly through to your extension ... well, you can see the problem telco would have determining if there were really a PBX hanging out there. Some folks do this and actually put a small PBX (one of the small Panasonic units or some such) out there ... there is no law that says you have to have more than one POTS business line coming into your PBX! But I've also heard of folks putting something like a dialer unit there (programming it to "eat" a leading "9" digit, so if a telco tech ever checks the line, sure enough, he'll have to dial a "9" to get an outside line) or just connecting the end that's supposed to be connected to the PBX right to a POTS line. The latter is probably a violation of telco tariffs, though. But a small PBX is cheap, particularly if you buy it on the used market (do you get Telecom Gear magazine? There are probably dozens of suppliers of used PBX's in there). > I have several unanswered questions: > Neither rep could explain to me how "engineering" computed the mileage > numbers for the "foreign exchange service" rates I was quoted.

Unfortunately, the mileage charges are something you cannot get around *UNLESS* you can somehow provide the link that straddles the exchange boundary yourself (which is why I suggested trying to find a property, possibly a large farm, that straddles the exchange boundary). Your state PUC should be able to give you both information on how the distance is computed, and the exact exchange boundaries for the exchanges in question (which would aid you in finding that large farm I spoke of). Actually, if you had given the exchange names, someone here that gets this data might have been able to give you the "official" mileage between CO's. > Can anyone define the true meanings of these terms for me ? The "surburban mileage" is the distance between your central office and your home (and if you use the scheme I mentioned above and can't supply the link crossing the exchange boundary yourself, there may also be "surburban mileage" at the other end ... this would probably be true in cases 1) or 3), but hopefully would not be the case if you went with number 2), because the OPX line could be cross-connected at the distant central office. The "distance between rate centers" is just a fancy way of saying "the TARIFFED distance between the serving central offices." That may or may not coincide with the actual physical location of the telephone exchange building (originally it would have when the exchange first came into existance, but if the exchange has been physically relocated since, the "rate center" would likely stay at the original location). When you say that you were quoted "three quarter-mile units of suburban mileage", that probably means that your office is about 3/4 of a mile airline distance from your central office. If they quoted you "37 quarter-mile units between rate centers", that means they are figuring 9.25 airline miles between the original centers of the exchanges. Since the mileages you gave are quite different than that, I suspect that either you're a bit off on the true airline distances involved, or one or both of the exchanges has been moved, or the person giving you this information flat out gave you wrong information. That being the case, I would ask (again via the PUC if necessary in order to get a response) for a WRITTEN quotation on company letterhead for any service you plan to order, so that you avoid any nasty surprise after the circuits are installed (the old "I don't know who gave you THAT figure for the mileage, but it certainly isn't correct" trick!) > The business service rep said the location of the rate centers was > "proprietary". Can this be true ? They may be "proprietary" in the sense that the information is "owned" by the company for copyright purposes (and even that interpretation may be a bit of a stretch), but it's certainly not top-secret informa- tion. The PUC should be able to give you this information. If you had given the exchange names, readers with access to the V&H tapes could probably have given you this info as well. > The residence rep said that unmeasured (untimed) FX service was no > longer available.

Keep in mind that if you have mandatory measured service, there is no way around that. But in many areas, the telco charges on a per minute basis for both INCOMING and OUTGOING usage on an FX line, even though unlimited flat-rate service is still available to non-FX customers. The bottom line is that they don't like to lose toll revenue, so they have repriced FX in such a way to make it financially unattractive. So what you have to do is order something that is functionally equivalent to FX (or that will at least meet your needs), but that costs less, if at all possible. > Do they actually allocate a circuit (or subchannel on a T1) > permanently, or do they allocate on the fly? Gee, could I get a fast > busy from the local CO instead of remote dial-tone on a bad day? It depends on the type of service you have, the serving telco, etc. so I'll leave that question to those more knowledgeable about the inner working of the telco. The thing to keep in mind is that there will always be circuits available for untimed use (broadcasters, background music providers, alarm system companies and others that need a 24 hour per day connection use them) but the questions are "Can you afford one?" and "What equipment will you need to provide to give you the functional equivalent of an FX line?" > I assume that the real cost of providing service to residences and > businesses are the same. I further believe that business usage IS > rate sensitive. Actually, the vast majority of telco costs (particularly on calls within a local calling area) bear no relation at all to usage. The only time usage increases costs is when a telco has to add equipment to handle an increased volume of calls, and that is really a rare occurance on modern digital switches. This is even more true as fiber cable replaces copper, since you don't have to replace the cable to expand circuit capacity. Paradoxically, as usage-induced costs become a lesser percentage of telco costs, telcos have pushed harder and harder for usage-sensitive billing. The one kernal of truth in your statement is that businesses do tend to make calls during the heaviest usage periods, while residential customers (taken as a whole) tend to make more of their calls in the evening hours. Thus, if telco DOES have to add equipment to handle increased usage, it's most likely going to be driven to do so by the needs of business customers. > Is this assumption way off? > If not, why are residences given more incentives (through lower rates, > additional "plans", etc) to make more calls, yet businesses are not? Telco does whatever it can to maximize profits. The typical business knows that it HAS to make toll calls from time to time; it doesn't have the luxury of saying "We're not going to make any toll calls." But residential customers can and do avoid making toll calls because of the cost. What telco tries to do, then is come up with packages that will cause customers to actually spend MORE on toll than they normally would. For example, if an "average" customer normally makes only $3.00 of intraLATA toll calls a month, the telco might come up with a $5.00/month plan that would give the customer much more calling time. If they can get that extra $2.00/month, it really doesn't matter that much how many extra minute of usage it costs them, since the circuits are already there and generally aren't nearly fully loaded during the times that the calling plans are in effect. > The residence rep suggested that the coming Intra-Lata competition > would precipitate a variety of new, more competitive rates and > "packages". He also said that some "very short haul" Intra-Lata calls > would be "protected" from competition.

It shouldn't, and if it were any other state I suggest that the rep (or whoever told him that) was doing some wishful thinking. But you are in California, and from what I've heard, the PUC out there doesn't always operate in the same way as any other PUC might (I'm trying to choose my words carefully so as to be chartible). In Michigan, all toll calls are open to competition, and Michigan Bell has offered some really attractive intra-LATA calling plans. Unfortunately, these aren't available to GTE customers, and for some reason Michigan Bell and GTE do not compete for intraLATA toll traffic in each others' territories, even though I believe they legally could. In my opinion, you're not going to see a lot of these phoney (pardon the pun) charges disappear until there is full competition for local phone service. I believe it is coming, and as far as I'm concerned, it can't come fast enough. Oh, one other thing. In your particular situation, I spoke of providing your own circuit across the exchange boundary, and using a couple of POTS lines and a WATS extender/call diverter/similar device. While I was thinking in terms of a physical cable (provided by you) crossing the boundary, keep in mind that if you are knowledgeable enough, you might be able to achieve something similar using a short range infrared link, or even short-haul microwave. Since you indicate that the community you're trying to link up with is on an adjacent mountain, it opens the possibility of using some line-of-sight form of communication. Without knowing the particulars of the nearby terrain, I can't say much more than that. The initial cost of microwave tends to be expensive; infrared is less so but has a much shorter range and is more susceptible to interruption by heavy rain, etc. I would encourage you to be creative, explore various options, and let us all know if you find something that works. I'd also encourage you to summarize any other helpful responses you may receive (I *hope* this one is helpful!). :-) I think this is a problem that is shared by many, many telephone users that live in places where the local calling areas appear to have been designed by Scrooge himself!

The #5ESS switches and the time-sensitivity leads me to > wonder about the implementation. I have unmeasured Residence Foreign Exchange Service, and have had it for at least seven or eight years. I am charged for 14 foreign exchange quarter miles and four quarter miles of suburban mileage. The former is the air mileage (3.5 miles) from my house (in the Boulder Creek exchange) to the exchange boundary for the foreign exchange (Los Altos). (I lucked out in that regard; most people would be further away.) I pay the same suburban mileage on my local phone; it simply represents how far beyond the basic service radius my house is from the local CO. (I am about seven air miles and eight wire miles from the CO.) > Do they actually allocate a circuit (or subchannel on a T1) > permanently, or do they allocate on the fly? Gee, could I get a fast > busy from the local CO instead of remote dial-tone on a bad day? My foreign exchange circuit is essentially a leased voice-grade line from my house to the Los Altos CO (via Boulder Creek, Santa Cruz, and Los Gatos). Sometimes a component goes out at one of the intermediate exchanges, and a repairman has to be dispatched to fix it, so I hear about the locations of various failures. > I assume that the real cost of providing service to residences and > businesses are the same. I further believe that business usage IS > rate sensitive. When I last inquired some years ago, business foreign exchange was always measured, just a regular business service was always measured. Now, of course, the local calling area usage rates are quite low (sometimes as low as $0.01 per minute), so the usage charge is not as high as it once was. > If not, why are residences given more incentives (through lower rates, > additional "plans", etc) to make more calls, yet businesses are not? The costs are of course identical, except for the possibility that a business line may be in use a greater fraction of the time, thereby tying up a larger fraction of the central office switch's capacity. > The residence rep suggested that the coming Intra-Lata competition > would precipitate a variety of new, more competitive rates and > "packages".

Charging business more to subsidize residence service is politically correct. With the growth of competition, political correctness is slowly giving way to economic reality. William J.
