How does Bonded T1 work?
Covad uses multi-link point-to-point protocol (MLPPP) to combine two T1s together to deliver a coherent 3 Mbps of symmetrical bandwidth. There is no need to implement load balancing over two separate T1s.

How many T1s are bonded?
Two T1s are bonded. Bonding of more than two T1s will be provided in the future.

What T1s can be bonded?
T1 circuits must be from the same POP and at the same customer location.

What is the Bonded T1 coverage area?
Bonded T1 has the same nationwide coverage area as TeleXtend 1.5. You can enter your telephone number and address to see if your location pre-qualifies for service.

Is the Service Level Agreement (SLA) different for Bonded T1?
No. Bonded T1 is backed by the same industry-leading SLAs as single T1.

Do I order two T1s?
No. When you place your order, select 'TeleXtend 3.0'.

How do I know which speed is right for me?
Our Sales Consultants will help you determine exactly which speed is best for your needs. Some of the things you should take into account are: applications you are running, number of employees using the connection.

What hardware is required?
The Cisco 1841 is the CPE required for bonded T1. More information can be found at: http://www.cisco.com/en/US/products/ps5875/.

If I already have a Cisco 1841 CPE, can I use it?

If I already have Netopia or Siemens CPE running T1, can I use it in place of the Cisco 1841?
