T1 Access Unit with High Speed Data andDrop & Insert
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.
