3.10.11.2 — TDM2Eth
E1 or T1 traffic both internal and external to 9500 MPR equipment.
example using E1 traffic.
Flow Id present (user defined)
All the parameters must be configured compliant with the MEF8 standard
Adaptive or differential clock recovery supported
Bandwidth guaranteed (according to QoS Æ Highest Queue Priority association)
Destination MAC added before going into whole network (MEF8 compliant)
Only one of the IWFs belongs to 9500 MPR and the packets are supposed to exit the 9500
MPR network.
• MAC addresses: in all involved nodes are determined as consequences of the cross
connections; the only exception is the Ethernet Terminal Node (the node where the
TDM2ETH traffic goes through an user Ethernet port). In such ETN the source
address is the node Mac address, the destination Mac address will be provisioned by
MCT/NMS.
• Payload size: is fixed to 256 bytes
• ECID: provisioned by MCT/NMS, 2 different values may be used for each direction
(ECID = Emulated Circuit Identifier)
• TDM clock source is provisioned by MCT/NMS: clock recovery adaptive, clock
recovery differential
