T1 Access Unit with High Speed Data and E&M
Analog PBXs (shown in the following diagram) typically communicate on trunk
lines (lines between switches) with a type of communications protocol called
E&M.
The T1 access unit fully supports this application. The T1 access unit supports up
to three 8-port E&M APMs. In the example shown in the diagram, eight time slots
could be assigned to the voice ports, two time slots to the FEP-Cluster controller
link, and up to 14 time slots to the router link. This provides the following:
Voice – Eight telephone calls
FEP-CC – 128 kbps
Router – 896 kbps
