Tierzero Bonded T1 FAQ’s
How does Bonded T1 work?
Multiple T1′s (2-8) are installed in your office. By themselves, these are separate circuits. However, we terminate them in to the same router at your location. The “Bonding” refers to a software process on the router. It happens at both ends of the circuit and effectively turns several circuits into one big one. On the back of your router there is only one Ethernet connection coming out – from here you get all the bandwidth of Bonded T1′s.
How fast is a Bonded T1?
A single 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. You can Bond 2 to 8 T1′s. 2 T1′s = 3 megabits, 3 T1′s = 4.5 megabits, 4 T1′s = 6 megabits, 5 T1′s = 7.5 megabits, 6 T1′s = 9 megabits, 7 T1′s = 11.5 megabits, and 8 T1′s = 12 megabits,
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. It also runs the software that allows us to “Bond” the T1′s. 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 and “Bond” the T1′s we do not allow customer access to it.
Can I run VoIP over my Bonded T1?
Yes. Bonded 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 Bonded 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.
