T1 Access Unit with High-Speed Data and
Drop & Insert
3-6
In the example shown in the following diagram, voice and data are mixed. The
Drop and Insert feature of the T1 access unit allows voice information to be sent
from a remote site to a large site that contains a digital PBX. People at the distant
end can make calls.
Multiple routers and data lines require adding a Sync Data APM to the T1 access
unit, because more than two data ports are needed.
