2.3 Telephones and Home Wiring
•The telephone jack port labelled "1", on the rear of the ATA, is used for your Primary TBB line. Simply plug your phone(s) or House Wiring into this port.
•The telephone jack port labelled "2" (not available on all ATAs currently in use by Primus) is used for a different (second) Primary TBB line, if you have one. Simply plug your phone(s) or secondary line of your House Wiring into this port.
•The LINE jack is used to connect an active POTS LINE to the D-Link DVG ATA.
Remember to verify the Cables and Jacks on the ATA and telephone(s); especially if you have any problems.
•Refer to the Primus TBB Wiring Guide
•There is also an excellent and thorough discussion of home wiring (including diagrams and photographs) provided by Michigan Telephone.
•As described in the above links, ensure that the POTS line (from outside) is disconnected from the demarcation block (usually inside your home).
•Your connecting block must not include any wiring or devices besides the wires necessary for your internal jacks. Even if your POTS line is disconnected, make sure it (and any extra capacitance) have been removed from your demarcation point connecting block. For example, a fairly large capacitor on your phone block will hold the line open when you hang up. Removing this capacitor will resolve the problem.
•With DryLoopDSL, the Telco's former POTS line still needs to be wired to your modem. For example, if this is done through the existing telephone wiring, care must be taken such that this circuit is not wired to the ATA in any manner. The DryLoopCircuit to the modem MUST be isolated from any house wiring that is connected to the ATA's telephone ports.
•If you are unsure or are having problems using TBB (you do not get dial tone, or the phones do not ring), simply disconnect the house wiring from the demarcation block and connect the house wiring to another (new) block.
•Depending on how you've chosen to set up your home wiring in conjuntion with your ATA, you may decide to add additional lines. An excellent primer can be found here.
•See further details on How many phones can be connected to the DVG ATA ?
•For Home Alarm systems, refer to Support of dialout on security system with TBB.
An unofficial Primus perspective:
Due to this limited power, there is a maximum number of devices (telephones, wireless base unit, fax modems, answering machines, etc) that can be connected to the ATA either directly or through the House Wiring. Devices that rely on the power supplied from the telephone line will likely reduce this number.
The "maximum number" will vary for each user based on the types of devices used, and the house wiring involved.
[POTS lines also had a limit defined in 3-5 REN, although this was not generally obvious as more recent telephones are electronic and have their own power supplies.]
Although Primus does not recommend connecting more than a few phones (see below), some users have connected up to six phones to the ATA through their house wiring, using no power boosters, with no problems at all. These users are most likely using electronic phones (each with their own power supply).
If you have problems with devices not working correctly (such as phones not ringing):
•Verify the DVG Hardware Version (if you are using the D-Link ATA).
•Test each device by plugging it in one at a time into the applicable ATA port ("1" or "2").
•You may have too many devices plugged into the circuit. A defective - or HIGH LOAD - device will load the circuit, and may cause the ringers to fail. Try different combinations of devices on the circuit. Unplug one device at a time (while leaving others plugged in) to perhaps isolate a defective or HIGH LOADING device.
• In some extreme situations, you may have a defective ATA; but this should be rare.
An unofficial Primus perspective:
If you do encounter a problem, try using fewer phones on the circuit, or try the answering machine by itself to isolate the problem. Refer to the following links for further information:
•How many phones can be plugged into the DVG ATA?
•DVG Hardware Version
NOTE: This feature currently has some issues - an incoming PSTN call will generate a loud BUZZ if you are on the TBB line.
You can connect an active POTS LINE to the DVG LINE port to enable you to use the POTS line from your single line telephones connected to the DVG ATA - which normally use the Primus TBB service - on port "1".
•Incoming POTS calls will ring on the POTS telephones as well as all devices connected to the DVG "1" port. When you answer with a TBB connected telephone, as you normally would, this now effectively "disconnects" the Primus TBB service from the DVG ATA until you end the POTS call. During this time, any TBB incoming calls are handled as defined in TBB Web Portal Concierge for a DVG Out Of Service.
•Outgoing calls will always be routed through the Primus TBB line unless you use the DVG's ACR Feature.
If your TBB line goes Out Of Service (OOS):
[due to Power Outage, Internet (ISP) connection OOS, Primus TBB servers OOS...]
•Incoming calls on your TBB service will be handled as configured by the account's settings in TBB Web Portal Concierge.
•All outgoing calls will be connected to the LINE port; thus providing an automatic outgoing backup service. Remember that these calls will be handled by your POTS line provider, and you need to take into account any different dialling sequences required, or unexpected Toll charges that may be applicable - based on your particular situation.
TBB user Bruce setup a system using a proprietary format called Contact ID from Honeywell/Ademco. He could not get this to work at all, since it communicates in DTMF "touch tones" and there was too much echo on the line (at the time).
He also tried the "SIA" format (Security Industry Association). This is a universal format generally regarded as the most modern. It worked after he activated the "fax" option for his TBB line (by calling Primus) - SIA generates modem-like signals rather than DTMF touch tones.
Please note that some telephone functionality problems may not be the result of incompatibility, but reflect another VoIP or TBB issue. In addition, there are 2 different versions of the D-Link ATA--versions A1 and A2. Some phones (Motorola and vTech) are known to have problems with version A1 (primarily, they don't ring). These same phones may work perfectly fine with version A2.
The following list is (to the best of our knowledge) compatible with either D-Link DVG ATA version.
GE 900MHz Cordless Phone (26938GE3)
Panasonic KX-TG2214 2.4GHz
Panasonic KX-TG2314B (multi handset)
Panasonic KX-TG6500 5.8GHz Multi Handset
Panasonic KX-TGA500 5.8GHz
Panasonic KX-TGA520CM 5.8 GHz multi-handset
Siemens 2.4GHz with 6 handsets
Uniden DXI-5186 5.8GHz
Uniden EXI976 900MHz dual handset (this is the phone provided free by Primus)
Uniden TRU446-2 2.4GHz multi-handset
Uniden TRU-8866 5.8GHz Digital cordless (2 handsets)
Phones reported as uncompatible with TBB:
Motorola MD-451 2.4Ghz
However, there are some problems with certain phones that use proprietary signalling (on the telephone wire) that:
- provide additional Telco services (text, weather, stock info...)
- communicate with another similar phone in your house (data exchange...)
You may have to disable/deactivate these features for these types of phones to work correctly with TBB.
For example, TBB user Erik notes that Vista350 phones with i-Select (or similar) services activated on the phone may experience inbound calls dropping to their second alternate # after 10 seconds. Disabling the i-Select services resolved the problem.
