FastPAD

A FastPAD connection is a connection where at least one end terminates on a FastPAD. FastPADs always connect to the network on a Frame Relay composite link to an FTM or FTC card. FastPAD enables you to concentrate voice and data connection types as a Frame Relay connection joined to an FTC or FRM card.

NMT designs FastPADs automatically when FastPAD connections are added to the Bursty Traffic, Data Traffic, or Voice Traffic table and the model is based on switch software release versions less than 8.2.5, or 8.4.0 to 8.4.9. NMT will also design FastPADs when FastPADs are specifically called for in the Feeders table and connection hub IDs match Feeders table hub IDs.

The FastPAD comes in two sizes, one with eight slots and one with four slots, called the FastPAD micro. By default NMT

•Configures as many FastPADs as required to support the traffic

•Chooses an 8-slot FastPAD unless no more than four slots and one low-speed data port are needed, in which case the NMT chooses the FastPAD micro

•Acts on the assumption that the speed of the composite link is limited by the maximum speed supported by the FTC card (512 kbps)

Refer to Table 4-22for information on modeling a network that uses FastPADs.
