FastPAD
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 4-22 for information on modeling a network that uses FastPADs.
Setting up multiple
MC3810s at the same
site
Data Traffic table, Voice Traffic table, Bursty Traffic table
• Hub ID field: The ID is given to the port of the FTC/FTM card on the
IPX/IGX that connects to the specific MC3810. ID values can be
— 0, indicating no unique port constraint.
— Slot and port: mm.nn
where mm = 1 to 32 and nn = 1 to 31
For connections between multiple
MC3810s at a site or to associate
specific connections with specific
MC3810s, use the Hub ID field for all
MC3810 connections that originate or
terminate at that site.
All connections associated with one
specific MC3810 should have the
same Hub ID throughout the three
traffic tables.
Changing Default
Parameters
Feeders table
• Hub ID field: Enter Slot Port (e.g., 6.4).
• Type field: Enter 3810 for any MC3810.
• Speed field: Enter the speed you want.
Data Traffic table, Voice Traffic table, Bursty Traffic table
• Hub 1 ID field: Enter the Hub ID value entered in the Feeders table (e.g.,
6.4).
• Hub 2 ID field: Enter the appropriate Hub ID value.
You can specify the maximum speed
of the feeder trunk, for example,
64 kbps, 128 kbps, or 256 kbps.
If you specify a speed of 0, NMT
chooses the best one.
