Four-Port, OC-3 Path Protection
Node ID 0 has four DS1-14 cards to provide 56 active DS-1 ports. The other sites only require two
DS1-14 cards to handle the eight DS-1s to and from the remote switch. You can use the other half of
each ONS 15454 shelf assembly to provide support for a second or third ring to other existing or planned
remote sites.
In the OC-3 path protection sample, Node ID 0 contains four DS1-14 cards and two OC3 IR 4 1310
cards. Six free slots can be provisioned with cards or left empty.
Figure 12-16
shows the shelf setup for
these card.
