Router shelf 1, one T3 plus two T1s—dial-shelf backplane-ds0 part2ct1ct3isdn
Router shelf 2, one T3 plus one T1—dial-shelf backplane-ds0 part1ct1ct3isdn
This setting combination provides 1150 DS0s (four UPCs) to one router shelf and 897 DS0s (three
UPCs) to the other for a total of 2047 analog calls terminated. This leaves 146 spare ports on the router
shelf 1 side, and 75 spare ports on the router shelf 2 side. This leaves one empty slot, but does not require
any DMMs to be added. The router shelf load in this configuration is more even than in option 1.

This setting combination provides 960 DS0s (three UPCs) to one router shelf and 960 DS0s (three UPCs)
to the other for a total of 1920 possible analog calls terminated. This leaves 12 spare ports on the router
shelf 1 side, and 12 spare ports on the router shelf 2 side. This leaves no empty slots, but does not require
any DMMs to be added. The router shelf load in this configuration is evenly split.
