Additionally, data/voice from cards in the 360-80 can be “re-inserted” into any vacant timeslots to the remote loca-
tion. This allows better use of the T1 timeslots by keeping them as full as possible between locations. See
tions to reduce the number of T1s needed between locations by keeping the T1 full. If a fault occurs in the 360-80
system, the T1 into the T1-S is connected to the T1 into the ST1U, bypassing the 360-80 system.

Drop and Re-Insert Application #2
Another configuration that can use the drop and re-insert capability allows the system to handle more than 2
types of circuits at a location. In this configuration, the drop and re-insert capability is used to combine the card
types in multiple 360-80s at a single location to allow more card types at the location. Each bank has a different
card type to allow more interfaces to be serviced at the location. This allows flexibility when customer require-
ments change.
