I have a CISCO 2600 series router.  I need to configure it for Multi Link Frame Relady.  My telco tells me that my equipment has to support the FRF 16 standard in order to work.  My question is can I do this with regular CSU's?  Do I need something different even though my router supports this standard?  Thanks.

FRF 16 is standard of Frame Relay Fragmentation ...

Cisco 2600 series have support for Multilink Frame Relay ...

Multilink Frame Relay feature enables you to create a virtual interface called a bundle or bundle interface. The bundle interface emulates a physical interface for the transport of frames. The Frame Relay data link runs on the bundle interface, and Frame Relay virtual circuits are built upon it.

The bundle is made up of multiple serial links, called bundle links. Each bundle link within a bundle corresponds to a physical interface. Bundle links are invisible to the Frame Relay data-link layer, so Frame Relay functionality cannot be configured on these interfaces. Regular Frame Relay functionality that you want to apply to these links must be configured on the bundle interface. Bundle links are visible to peer devices. The local router and peer devices exchange link integrity protocol control messages to determine which bundle links are operational and to synchronize which bundle links should be associated with which bundles.

Configuration is not that simple ... kindly visit the link below to configure you multi link on 2600 ...

Thank you very much, it seems that your answer is in regards to the router interfaces.  If this is the case, does the csu config not matter?  No special csu is needed?  What happens at this connection for multilink frame relay?  Thanks for the help.

i think csu doesnt matter, but you need another serial to configure multi-link, as this phenomenon include more than one physical interface ... you can find it on cisco page which i forwarded, you can find a little in the config below ...

interface mfr0
 frame-relay multilink bid BUNDLE-A
!
interface serial0
 encapsulation frame-relay mfr0
!
interface serial1
 encapsulation frame-relay mfr0

can we close this question? discussion may proceed ...

I understand that I need two physical interfaces.  What I'm trying to make sure of is do I need to do anything special for the csu's?  Can I just use regular one's like Adtran ace's?

i think Its not depending on the physical media or the devices you are using, if both ends are supportive to mfr then go ahead with the sample config ...
