CAT5 cable

I have Verizon DSL

Since my house wiring is very old, I want to know if its possible to connect a cat5 cable from the modem to the phone line box ?
If so, please tell me how, I would appreciate very much.

Pick one pair and use that pair from the phone line box to the jack

Is it possible from the inside, the little box, instead of the outside phone line box?

Without knowing what "a little box" is it is impossible to tell.

Keep in mind the DSL signal traveled thousands of feet to get to your house. Unless inside wire is terrible it is not going to make a difference.

Before you spend the time rewiring temporally connect the modem the the test jack on the phone company demarc. That is usually outside near the electric meter but could be anywhere. If stats are better, either sync speed or margin, then something within your residence is degrading performance.

If you are going to the trouble of installing new wiring I'd recommend installing a while house POTS/DSL splitter. A splitter does a better job isolating DSL from voice and eliminates the need to use inline filter on all non-DSL devices. It is beneficial if your signal is marginal or you have a lot of phones connected to the line.

Well this is my stats of my modem. Plus, I only have one phone connected, with a filter of course.

Transceiver Statistics

Transceiver Revision: 7.2.3.0
Vendor ID Code: 4
Line Mode: G.DMT Mode
Data Path: Interleaved

Transceiver Information Downstream Path Upstream Path
DSL Speed (Kbits/Sec) 5952 864
Margin (dB) 8.5 11.0
Line Attenuation (dB) 38.0 23.0
Transmit Power (dBm) 19.3 11.9

I have Verizon Internet Enhanced package which is from 3.0 Mbps up to 7Mbps. I when I run speed test online, I usually get 5.5 Mbps and .75 Mbps upload ON AVERAGE.

I know sometime its hard to tell if it will make any difference sometimes when changing the wiring system, but can you predict if I need it based on the information I gave you or its too hard to tell. Thanks.

Anyways, separating the DSL and phone line is a very good idea. If it doesnt improve anything, like you said. There is no reason to do it. Correct?

Alright. I will check if stats are better once I connected it directly to the phone company demarc.

Thanks for the tip, If I decide to install a new wiring into my house.

i would say that there might be an issue with inside wiring. you have attenuation of ~40dB, yet your margin is rather low for the speed package you have. as tschmidt suggests, try connecting it to outside box, and see if it's better there.

@csupomona.edu

Alright, will do once I get home and have time as well.
Lets say it does improve my stats, can I buy a dsl splitter that works from the inside that can separate dsl and phone line.
Is it possible? Sorry for having lack of knowledge.

I actually rent and will need to ask permission from my landowner if I want to do anything change anything at the NID (outside).

At 38 dB you are at about 9,500 feet from the DSLAM. As Demonfang See Profile mentioned margin is a bit low but not all that bad considering speed. Tx power is maxed out so what you are seeing is your DSL is syncing at maximum possible rate so unless you are able to improve the circuit somehow.

Be interesting to see if stats are any better at the NID.

DSL needs a filter to protect non-DSL devices from the high frequencies used by DSL. As you surmised either inline filters are whole house splitter will do the job. As long long as you install it correctly it can't do any harm.

If you are a normal Verizon DSL customer using PPPoE and ATM the total overhead TCP/IP/PPPoE/ATM is 14.4% so best case speed test report is 5.095 Mbps dwn/ .74 Mbps up. If you were really getting speed test results of 5.5 Mbps it means either the speed test is wrong, or you sync speed at the time you ran the test was higher then you posted.

I'm not using PPPoE, I'm pretty sure I am not. I'm in California and using DCHP.

Here are my speed results.

This is my stats right now, and the speed test I provided above is current. It seems that margin is even lower than before. So what does that mean?

Transceiver Revision: 7.2.3.0
Vendor ID Code: 4
Line Mode: G.DMT Mode
Data Path: Interleaved

Transceiver Information Downstream Path Upstream Path
DSL Speed (Kbits/Sec) 6208 864

Transmit Power (dBm) 19.2 11.8

I just checked outside my house, and I don't have those regular NID boxes. The box is really old and small.

No NID outside, just old fashioned silver box. Can I still test it?

5.35/.73Mbps is reasonable speed for sync rate of 6208/864. PPPoE only adds .6% overhead so in your case best case speed at the current sync rate is 5.38/.748. What this means is that your connection is not experiencing congestion outside the DSL physical interface. That is good news as often times poor performance is due to congestion within the ISP network causing speedtest report to be much lower then the DSL connection.

Notice your margin is lower, that is due to higher sync rate and possible noise on the line.

As far a wiring test you have several options, in order of preference:

1) Call Verizon (Phone not DSL) and tell them you need to add wiring but your residence does not have a NID and ask to have one installed. New NIDs use gas tube transient protectors rather then carbon block. They do a better job protecting from lightning strikes. Also carbon arrestors tend to be noisier - especially over time. A new NID with gas tube protectors may improve DSL speed a little.

2) Since you wanted to rewire your apartment I assume you are comfortable working working with phone wiring. Open circuit voltage is around 48 volts but when phone rings 90 v 20Hz AC is superimposed on the line so it does represent a shock hazard.

Disconnect inside wire from the protector, leave the drop wire connected. That is the wire going to the pole or underground feeder. Temporally connect a jack to the two terminals and connect the modem and see what happens.

3) Disconnect anything plugged into the phone line and and see if stats improve. You indicate you only have a single phone double check for computers, settop boxes answering machines etc connected to phone line. Open up any accessible jacks and look for corrosion between the terminals.

On another note notice your modem is reporting G.DMT mode that is first generation ADSL. Assuming your modem supports second generation DSL ADSL2/ADSL2+ try getting your circuit switched to an ADSL2+ line card. ADSL2 does better on marginal circuits. The switch ought to tweak speed and/or increase margin a little.

Thanks for clearing everything up. Now I understand more things now.

Anyways, Will it be free or I will get charged if I ask Verizon to install a New NID ?

Yes, my modem supports ADSL2. Who do I need to contact specifically? Can VerizonDirect be a better choice?

Telco's are required to provide customer demarcation point aka NID but they may balk at installing one because nothing is wrong with the circuit. I'd call and see what they say, let them know you need to add wiring to your apartment and it is not safe to do so without a NID so customer wiring can be disconnected.

If they stonewall you the next step it to get in touch with your state public utility commission (PUC) and ask them to assist.

Verizon online does not specifically market ADSL2 so may be difficult. I'd try calling support first to see what happens. If they refuse try the Verizon Direct route. Unlike the NID they are under no obligation to switch to ADSL2 as they are able to provide an acceptable level of service.

Be warned Verizon may "optimize" your speed rather then switching you to a ADSL2 line card. In that case you may be throttled to a lower speed to stabilize the connection.
