Unfortunately if the problem started after a lightning storm the modem is almost certainly fried. I used to work at the UK's largest IT support call centre, we used to check the weather reports every morning because if there had been a lightning storm anywhere in the country we'd get a slew of calls from that region from people who could no longer connect to the web. Phone-lines collect a large static charge during a storm and are unprotected. I'd strongly suggest you contact the supplier regarding replacement.

Your DSU/CUS can set clocking/timing from the local central office (CO) or internal.
There are MANY external DSU/CSU in the market.
Example: Adtran and Lucent

Please reply with what type of T1 DSU/CSU is connected to your unit.
==== If your setup does not use an external DSU/CSU then look for setting for your internal T1 card.

Are all cards on the same rack?

My Phone Is Silow Procsessing And Hang After sometime.

Probaly not your phone connection but the server you are connecting to. Try a different phone number if available ( will connect to different server ). If problem persists, this is phone line test, take computer to friends house and try connecting, do not use friend's computer as this will not verify your computer malfunctioning.
Have come across phone line issues, line static being the worst for computer use.

What is a Lucent Pipeline P130-u-v35-asa used for

The short answer is.... It is a T-1 Router/Firewall that works with ISDN and Frame Relay. It uses the V.35 and BRI interfaces and requires an external CSU/DSU. It is NOT compatable with Cable or DSL internet service providers.

You have to isolate the problem. Please follow the steps below:

1. Connect the Blackberry into different USB port of the computer.
2. Try connecting the phone in to different computer to test if there's really a problem with the phone.
3. Try using different USB cable for the phone.
4. Check the user manual to see if you need to set it as "Mass Storage Device" before connecting it to the computer.

Otherwise, you need to consult the phone manufacturer for some advise.

Have a great day!

Connecting problems

Is it set to auto receive, is the tel line plug into socket marked line not tel. Is it used on a dedicated line, no extensions, if using ADSL you must have filter on line. If plugging standard phone in place of fax is dial tone heard and line is noise free, can you ring and speak fine on line using a phone. Is machine set to correct dial format for your country ie pulse or tone. When did it stop, have you had storms, phone work done, has it worked on this line before? I take it it copys ok is that correct.

My bet is A noisy phone line or B set to manual answer. More info equels better help, but I am short of free time now..

I have a new all in one with fax, I am not sure how to send a fax

You do not need a dedicated line. You just have to have a working phone line connected.

Fax won't answer

Fax machines are designed to work on a dedicated line, any other configuration is a **** shoot.

Buy a 2 port phone line adapter and plug it into the LINE port of the fax, it MIGHT work.

Must have DSL filter attached before fax, not sure how you are saying you have it setup, but phone line should come from wall then to filter then to fax socket marked line, phone should be hooked to socket on fax marked EXT, if you dont have dedicated fax line then fax number will be same as phone no.

If you have Adsl then there will be a lead from wall that splits into two, one goes to your modem (ADSL) and the other marke phone or line needs to go to fax socket marked LINE

Dedicated fax line on system phone

If you have a dedicated fax line, the fax should be connected directly to the phone line. If you have the fax line connected to one of your station ports, you may be able to see which LED lights up on your phone when the fax goes off hook. Or you can just try intercomming all extensions in order until the fax rings.
