Tierzero T1 FAQS
T1 is a unified digital technology that transmits Voice & Data over the same line, at the same time. Whether you want T1 Internet, T1 Voice, or both, Tierzero guarantees reliable, affordable service with friendly, 24/7 tech support.
Why is a T1 more expensive than DSL or Cable?
T1 is in a distinctly different class than DSL and Cable because it is a dedicated and secure line between you and the Internet service provider. With DSL and Cable your line is brought from your office to the service providers nearest aggregation point where many other customers are being aggregated. Your traffic and the rest of the other customers traffic are then put on a shared network. In almost all cases the bandwidth of the shared network is less than the sum of all the customers aggregated on it. This is call “over-subscribing” and is at the heart of the lower cost of DSL and Cable. You may see words like “best-effort” on your service level agreement. The thinking is that all the customers will not be using the bandwidth at the same time. In truth, sometimes they don’t. But if you are running mission critical applications like voice, video, or hosting your own business applications you may not want to spin the “best-effort” wheel. Depending on your business operation it only takes once or twice a month of not having the bandwidth when you need it to severally impact your business. This is when point-to-point, non-shared, dedicated service like T1 comes in handy and you won’t mind paying a little extra for it.
How fast is a T1?
A T1 transmits data at 1.54 megabits per second. It is an synchronous service meaning that is has equal speeds for both upload and downloads.
How come I only can use 5 of the 8 IP’s that are assigned to my T1?
The other 3 IP’s are used on the router that we provide you with and routers in the Tierzero network so we can route your traffic to the Internet. Without this the service doesn’t work.
Can I get more IP addresses?
Because of of the explosion of the Internet IP’s are in high demand. ARIN (American Registry for Internet Numbers), the body that allocates IP addresses, has asked all service providers to monitor the delegation of IP’s very closely. You can get more IP’s but we have to justify their use to ARIN and there is a small additional charge.
Can I use my own router?
The router that we provide allows us to proactively monitor your service. This is a key part of the service that you are paying for. If you need to add another router, you can always add it on the other side of our router.
Can I have access to the Tierzero router?
Since we use this router to monitor your service we do not allow customer access to it.
Can I run VoIP over my T1?
Yes. T1 is perfectly suited to run VoIP. Since it is a point-to-point, dedicated connection it offers the highest reliability for VoIP services.
What can I do to make the install go faster?
Filling out the worksheets completely and accurately does a great deal to speed the installation process. If there is a mistake or change in the paperwork sometimes the install process has to start all over again.
Can I expedite my installation?
Yes. There is a $800. charge for expedited installation which do usually make them go faster. This is pass-through charge from the phone company and they will not guarantee the install date nor refund the charge if they fail to expedite. However, this is your best bet if you are in a time crunch.
Do you supply a user graph so I can monitor my bandwidth?
Yes. You will be giving your login and password when the field tech installs your service at your location.
What do I do if my service goes down?
Call us at 213-784-1400 option 1 or email care@tierzero.com. However, chances are we already knew and are working on the problem. Typically we will call you before you can call us.
What if I outgrow my T1?
We can bond additional T1′s, up to 8, for 12 megabits per second or if your location qualifies we can offer Business Ethernet, 2 to 20 megabits or DS3 at 20 and 45 megabits per second. In some locations we can also offer Metro Ethernet which is 100 megabits per second.
