9500 MPR ERPS tail node support on Ethernet (G.8032) rings
Previous releases of the 5620 SAM had a limitation that all services could only begin
and end on Ethernet (G.8032) rings on the 9500 MPR. The 5620 SAM extends EPS
support to include tail nodes that connect to ERPS ring nodes. You can configure
several tail network configurations on the 9500 MPR including:
• a tail network of one or more MSS-4 or MSS-8 shelves attached to the ring to
create, for example, a tree or linear chain
• a tail network of one 9500 MPRe attached to the ring to create an 9500 MPRe
extension
• a head-end network of one or more MSS-4 or MSS-8 shelves
Figures 9-1 and 9-2 show the service configurations for ERPS tail nodes on the
9500 MPR.

9500 MPR ERPS tail node service provisioning
On 9500 MPR MSS-4 and MSS-8 shelves, you can provision any service on a tail
node; for example, TDM-over-Ethernet using a hybrid path. The services can
terminate on a ERPS ring node or on another tail node.
