15 APPENDIX F: MDR5800 SCALABLE 1-TO-4 E1 / 10 BASE-T
ETHERNET FUNCTIONALITY
There is a total of 10 Mbps combined send-and-receive data throughput capability via the Ethernet
interfaces on either side of an MDR5800 link.
As E1 tributaries are deactivated, more bandwidth becomes available for the 10BaseT Ethernet
Interfaces.
Case 1 : 3 x E1's active, 2 Mbps 10BaseT Ethernet possible in both directions i.e. 4 Mbps
aggregate.
Case 2 : 2 x E1's active, 4 Mbps 10BaseT Ethernet possible in both directions i.e. 8 Mbps
aggregate.
Case 3 : 1 x E1 active, 10 Mbps aggregate shared in both directions.
e.g. with a maximum of 6 Mbps in any one direction (leaving 4 Mbps for return traffic when that
occurs)
Case 4 : No E1's active, 10 Mbps aggregate shared in both directions.
e.g. with a maximum of 8 Mbps in any one direction (leaving 2 Mbps for return traffic when that
occurs)
