--------------------------------------- EXCHANGE SCANNING (99XX) --------------------------------------- Almost every exchange in the Bell System has test #'s and other "goodies" such as loops with dial-ups. These "goodies" are usually found between 9900 and 9999 in your losal exchange. If you have the time and initiative, scan your exchange and you may become lucky! Here are my findings in the 914-268 exchange: 9901 - Verifaction (recording of a/c and exchange) 9927 - Osc. tone (possible tone side of a loop) 9936 - Voice # to the telco central office 9937 - Voice # to the telco central office 9941 - Computer (digital voice transmission?) 9960 - Osc. tone (tone side loop -- may also be a computer in some exchanges 9961 - No response (other end of loop?) 9962 - No response (other end of loop?) 9963 - No response (other end of loop?) 9966 - Computer (see 9941) 9968 - Tone that disappears--responds to certain touch tone keys What you find depends upon the switching equipment in the exchange and the Telco operating company. Since I have done the above 914-268-99XX scan, Congers (268) has installed new switching equipment (DMS100). Some of the numbers are the same, but I have noticed that on the DMS100, the recordings are also stored in this area. 268-9903, 9906, & 9912 are all different recordings. Also, there are 2 fortress fone recordings at 268-9911 (deposit 5 cents or else) and 268-9913 (deposit 10 cents). In some areas (like Delaware), I have noticed that 9906-7 is ringback. If you find anything interesting, be sure to drop TAP a line. Have phun and remember it's only local call to see what your CO has in store for you! F.T.B.S. *****BIOC *=$=*Agent *****003 ===================================== 99xx TELEPHONE SCAN By TOM BROWN 2-June-84 ===================================== I have recently done a scan of all the 99xx numbers in the 376, 464, 665, and 582 exchanges. You just dial the exchange, 99, then the two numbers that you see in this list that are under the exchange you dialed. For example, if you wanted to dial a number in the 376 exchange, you would look in the list under 376 and pick out a 2 digit number, say, 71. To dial the number, you would dial: 376-9971... Get it? Well, if you do, here are my results: * = must dial 201 before the number 376-99xx xx= 01 Ring, answer roughly with small tone, silence 07 Ring, silence 16 Ring 20 Ring 21 Ring 22 Ring 23 Ring 24 1 second modem tone, tiny low tone, silence 25 Same as 24 26 Ring 27 Ring 28 Ring 29 Low tone (Low end of loop) 30 Silence (High end of loop) 49 Ring 52 Silence 53 Ring 54 Ring 59 Ring 64 Fast busy signal 66 Silence 68 Rough ring 69 Ring, voice answer (Payphone?) 70 Busy signal 71 Low to medium scaled tone 72 Ring, clicks 73 Same as 72 74 Same as 72 80 Rough ring 85 Ring 89 Rough ring, modem at 110 baud: prints "MILLBURN CO" 90 Changed to 527-7870 92 Ring 93 Ring 96 Ring 97 Ring 98 Ring 99 Ring 464-99xx xx= 01 Ring 03 Ring 04 Ring 05 NJ Bell Network Repair -- Jim Picker 06 Ring 07 Ring 08 Ring 12 Ring 13 Ring 14*Ring 15 Low tone for 6 seconds, silence (Low end of loop?) 16 Modem tone for 2 seconds, silence 17 Ring 18*Busy signal 21 Ring, silence for 10 seconds, low tone 24*Modem tone for 1 second, tiny low tone, silence 26 Ring 27 Ring 29 Low tone (Low end of loop) 30 Silence (High end of loop) (Soft low tone in background) 36 Ring 40 Tiny ring, busy signal 46 Silence 49 Modem tone for 2 seconds, silence 50 Same as 49 51 Ring 53 Ring 60*Modem tone for 1 second, tiny low tone, silence 62 Tone that goes up and down (high pitch) 63 Low funny tone 66 Silence 67 Same as 66 70 Busy signal 71 Low tone 72*Ring, soft clicks in background 74*Busy signal for 15 seconds, low tone 75 Ring 78 Ring 79 Ring 80 Ring 81 Ring 82 Ring 85 Ring 86 Ring 87 Busy signal 89 Ring 90 Ring 91 Ring 92 Ring 95 Ring 96 Ring 98 Ring 99 Ring 665-99xx xx= 00 Ring, "Cannot be completed as dialed from phone you are using" 03 Same as 00 04 Ring, silence 24*Modem tone for 1 second, tiny low tone, silence 29 Low tone (Low end of loop) 30 Silence (High end of loop) (Soft low tone in background) 36 Ring 37 Ring 46 Silence 49 Modem tone for 2 seconds, silence 50 Same as 49 66 Silence 67 Same as 66 70 Busy signal 71 Low tone 72*Soft clicks in background 74 Busy signal for 15 seconds, low tone 75 Ring 90 Ring 99 Ring 582-99xx xx= 24*Modem tone for 1 second, tiny low tone, silence 29 Low tone (Low end of loop) 30 Silence (High end of loop) (Soft low tone in background) 36 Ring 37 Busy signal 46 Silence 49 Modem tone for 2 seconds, silence 50 Same as 49 66 Silence 67 Same as 66 70 Busy signal 71 Low tone 72*Ring, soft clicks in background 74*Busy signal for 15 seconds, low tone 75 Ring ---------------------------------------
