COM310 Voice Communications Modem
6.4 Telephone Service
Telephone companies occasionally make changes in their equipment,
operations, or procedures. If you have any questions about your telephone
line, such as how many pieces of equipment you can connect to it, the
telephone company should be able to furnish this information upon request. If
the telephone company requests information from you concerning the
equipment that you have connected to your telephone line, the COM310 label
shows its FCC registration number and ringer equivalence number (REN).
COM310 information pertaining to the FCC and Industry Canada is available
in Appendices B and C.
If any of your telephone equipment is malfunctioning, you should remove it
immediately from the telephone line as it may damage the telephone network.
If the telephone company notices a problem from their end, they may
temporarily discontinue service. They should notify you in advance of
disconnection and give you opportunity to correct the problem. If not feasible,
they should notify you as soon as possible.
If the local phone company does not provide phone-line surge
protection, a Campbell Scientific surge suppressor should be
used. Refer to Section 6.6 for more information. NOTE
6.5 Telephone Transfers
The COM310 has the ability to do certain transfers by telephone:
1. Set/Get AT parameters in COM310’s Connexant chip set (Appendix D)
2. Retrieve word list from COM310
3. Install OS to COM310
4. Install new voice word file or add to existing words in COM310
There is some risk in performing such transfers by telephone, especially in
regards to remote sites. If you have need of doing such a transfer, contact
Campbell Scientific for details.
6.6 Connecting to a Surge Protector
Campbell Scientific offers two surge protectors (CSI model 4330 and CSI
model 6362). The 4330 and 6362 are essentially the same, except the 6362 has
hardware for mounting to an enclosure backplate.
The 4330 is also known as the 2374-01. NOTE
The 4330 and 6362 have a protector element for each line that consists of a
heavy-duty-rated, two-element gas tube, an external backup gap assembly, and
a switch-grade shorting mechanism. The gas tubes (tip and ring) are sealed in
a fire-resistant plastic body. DC Breakdown @ 100 V/sec is 300 to 500 volts;
DC extinguishing @ 52 V, 135 V, and 150 V is less than 150 milliseconds.
