This table is an example of how EFM Protection Bonding could be configured to protect traffic
going to multiple Network Channel Termination Equipment (NCTEs). Each NCTE could be
an individual port or entire device at a customer location.
In the example, each card in Slots 1 to 8 have EFM Protection Bonding. In the example, there
are only three to four Bonding Groups (BG) per slot, but there could be as many as 8. Each BG
(also known as a Bridge) is described below:
• BG 1 is shown in Yellow and the Bonding Engine is located in Slot 1. Every group of
• BG 2 is shown in Red and the Bonding Engine is located in Slot 2. Every group of Red Slots
• BG 3 is shown in Blue and the Bonding Engine is located in Slot 3. Every group of Blue
In this example, if the Bonding Engine in Slot 1 went offline, the EFM Protect Module would
take over the traffic going to and from the bonding groups associated with that Bonding
Engine. As a result, there would be no loss or reduced bandwidth going to the customer's
NCTEs. The EFM Protection Module will continue this protection until the Bonding Engine is
returned to service. It is important to remember that the Bonding Engine is physically located
in an access module. Correcting this situation may require replacement of that access module.
