There have been quite a few of you that have asked for some general answers to your questions. Here you will find answers to some of those questions. If you would like to see something else here please let our know.
We also have a more specific section from our Q&A taken directly from our TM-7PTEL Service Manual 5055. While these questions are directly related to our PTEL system they do apply to other systems as well.
1. What is TM7 and how is it
different from TM6?
1.b. How do I program frequencies and channels?
Telemobile's new TM7 series products are programmed (both frequency channel and many other options and variables) by an external PC running our TM-PC7 software program. The TM-PC7 software program is integrated into our SPS (System Planning Software) that is available from the "customer" section of our download library (password protected).
2. One (1) channel, Ten (10) channels, Thirty-two (32) channels. Can you explain?
The TM7 point-to-point PhonelinkŪ systems now come standard with 1-10 channels pre-programmed. If only one channel (frequency pair) is needed this will be programmed in channel #1. Nine additional channels are available in the standard product at no additional cost. You can add these frequencies later via computer software. The 32 channel option requires an internal hardware reconfiguration. However, the external software that is used to program is the same. You just need to check the box indicating 32 channels are required. There is a cost to expand from 10 channels to 32 channels. There is no cost savings for only 1 channel vs. all 10.
2.a. Is the 32-channel option available on the TM7 analog PhonelinkŪ systems?
TM7 analog single line systems (PTEL and E&M links) and the back-to-back duplex repeaters for each are designed for a maximum of 10 preprogrammed channels only.
3. How far can I change frequencies without retuning?
Telemobile's full duplex PhonelinkŪ systems have different internal modules (transmit, receive, power amplifier, etc). Each of these modules has a relatively wide frequency tolerance, however, they go through an internal duplexer so that the TX and RX signals can be used by a single antenna. The general tuning bandwidth of the internal duplexer is 400KHz. Frequencies within these 400KHz will work without any retuning required. For example, a one channel PhonelinkŪ with a transmitter tuned at 465.500 can be reprogrammed to 465.300 or up to 465.700. Each module (transmitter, duplexer, receiver, etc.) can actually cover a frequency band of 20-40MHz depending on the exact frequency. While most of the components on each module are the same from band to band there are some slight differences to optimize the performance for the exact frequency needed. The bands are overlapping.
4. What frequency bands are available on Telemobile products?
Telemobile offers our products in frequencies of 74-88MHz and 136-520MHz. Also products are available in the 1.4 and 2.4GHz bands. The 800 and 900MHz bands are generally reserved worldwide for paging and cellular telephone use. Therefore Telemobile does not offer products in that range.
5. Does Telemobile offer unlicensed spread spectrum equipment?
Telemobile products are "on frequency, licensable" products. We do not offer unlicensed spread spectrum products. Proper use of spread spectrum equipment generally means a low power, short range communication using high frequency equipment. This in contrast to Telemobile's focus of providing rural, long range wireless communications generally in the lower frequencies for better propagation over the distance and terrains that we have to encounter.
6. What are the physical differences between TM6 and TM7 products?
The TM6 and previous generation
products were all built on a die cast chassis with transmitter and receiver
on separate sides of the chassis requiring you to turn the radio over
back and forth to test and tune the unit on the bench. The original (TM6
and earlier designs) were built for full duplex mobile telephone service
although our main focus is now in fixed rural telephone applications.
7. What other changes and improvements are there in the TM7 over the TM6?
The TM7 now has a space designed in for internal power supply option. The standard product is 13.8VDC, however, internal modules can be added for 110VAC, 220VAC, 24VDC or 48VDC.
8. Is there an outdoor/weatherproof enclosure available?
Yes, Telemobile offers TM-7ENC outdoor enclosures for the new TM7 series point-to-point PhonelinkŪ systems. This outdoor enclosure takes the standard desktop of rackmount sized product and provides a weatherproof enclosure that includes coax lightning arrestor and two wire phone line protection as standard. The coax (antenna line) and phone line protection devices are available separately, however, they are included as standard in the weatherproof enclosure.
9. Can your system support payphone?
Yes, our point-to-point systems all can support payphone services (12 or 16KHz with or without polarity reversal). Separate modules and/or software are required for each product. Please contact your sales manager for details.
10. Can your system support caller ID?
Yes, Telemobile can support caller ID on some of our products. Because Telemobile controls our own design, development and production we have the ability to address any specific requirement you may have. We have developed a caller ID module for our single line point-to-point system. This captures the caller ID signal coming from the phone company at our exchange unit and then sends it over the air to the remote unit where it can be displayed on any standard caller ID box before the actual telephone connection is made. This feature was designed in based on a phone company request. To date we believe Telemobile is the only company offering caller ID option on a single line wireless PhonelinkŪ system.
Telemobile's TM-7PTEL with the Caller ID option added (to the FXO side of the PTEL) is built to the Phone Company Specifications. The installed module listens and grabs the "ID" (phone number) of the calling party (as long as your phone company offers this service). Technically the "ID" is sent from the phone company in-between the 1st & 2nd rings on incoming calls. The "ID" information is then sent over the air to the remote subscriber before the remote answers. Standard caller ID displays built into the phone or as a separate box (as offered by Telemobile) will work just fine.
11. Are you ISO 9001 registered?
Yes, Telemobile is ISO 9001 registered. ISO 9001 standard is the most stringent in the ISO9000 series including design, engineering, manufacturing, assembling and testing. ISO 9002 registration does not cover the design of the product and ISO 9003 does not cover the manufacturing of the product. Therefore a company that is ISO 9002 registered may not have control over their design and could be just an assembly company for someone else and an ISO 9003 company could be just a distribution firm that does not control design or production of the products they are offering.
12. Are your catalogs available on-line? How can I download them?
Yes, Telemobile's catalogs are all available on-line and we also can send a CD Rom digital catalog to you. In order to access our download section you must first receive a password to access the secure area of our website. These passwords are only given out by the sales manager responsible for each region. Please contact your sales manager for any additional support material you may need. It may be faster for us to send e-mail to you with attachments based on your specific requirements.
13. Is product training available?
Yes, product training is available at different levels. Telemobile's basic pricing structure is $1,000 per day per engineer to travel to your location for training, installation or other support related items. In addition to the daily cost there is a per-trip cost as well that is usually $4,000 to cover air travel, logistics, etc. A five day on-site engineer would cost $9,000 total. Factory training is also available for $800 per day for up to three engineers that are visiting at the same time. Travel and per diem expenses are not included. For other sales, marketing and systems planning meetings please contact your sales managers so that arrangements can be made. There is generally no cost for these meetings.
14. What full systems planning training do you offer?
Telemobile offers a FREE weeklong wireless telecommunication systems planning course. One of these courses is usually offered in conjunction with the USTTI (United States Telecommunications Training Institute), a Washington DC based group that uses government funds to subsidize travel and training costs for telecom engineers and officials from developing countries. See www.ustti.org for additional details. Telemobile's USTTI course is usually in June of each year. Telemobile also offers an opportunity to attend these courses privately. We currently offer these course twice a year, one in June and one in October. There is no significant cost required by Telemobile to attend one of these courses, only a small registration fee to cover hotel confirmation and the cost of the training material distributed at the course.
15. Where is my local sales office?
Telemobile has our own offices established worldwide. Our global headquarters location is in Torrance, California (greater Los Angeles area) supporting our activities in the Pacific Rim and all of North, South and Central America and the Caribbean. Our own office in the United Kingdom has two sales managers covering different regions, one is Eastern Europe including Russia and CIS and Western Europe as well as French speaking Africa, the other is English speaking Africa and the Middle East.
