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:
