2.8.15 Managed Services and profiles
Here below the association of managed services and profiles:
– TDM to TDM – This is the typical service associated to a traditional TDM network in which E1 traffic
is transported, switched and terminated inside a MPR network.
– TDM to ETH – This is the service allowing the TDM traffic to be aggregated and output in a single
ETH stream. On this service specific algorithms are applied in order the E1 is transported, switched
and provided to an external ETH network in standard format (MEF-8).
– SDH to SDH – This is the typical service associated to a traditional SDH transport network. STM-
1 traffic is transparently transported, switched and terminated inside a MPR network.
– ETH to ETH – This is not a real CES due to the native IP architecture of MPR. Ethernet traffic is
directly managed by the L2 switch on the Core board, thanks to the auto-learning algorithm, VLANs
etc.
– ATM to ATM – This profile allows the management of the ATM services inside a 9500 MPR network.
E1s IMA/ATM are terminated/reconstructed at the borders of the 9500 MPR cloud; encapsulation/
extraction of ATM streams into/from ATM PW packets is performed according to RFC 4717.
– ATM to ETH – This profile allows the ATM service to be terminated and encapsulated into an Ether-
net stream towards an IP/MPLS Core Network.
[1] TDM to TDM flow
– Definition: This service identifies a flow inside MPR network, in which E1 is transported, switched
and
terminated
.
– Application: Typical microwave 2G backhauling application, in which E1s are terminated before
entering into aggregation network.
[2] TDM to ETH flow
– Definition: E1 TDM input signals are packetized according to MEF8 standard; E1s are transported,
switched and provided to an external ETH network in standard format (MEF-8).
– Application:
• a) Typical microwave 2G backhauling application, in which E1s are terminated before entering
into aggregation network, where aggregation network is a packet network. E1s are not termi
-
nated at the end of the microwave backhauling and an end-to-end circuit emulation services
could be established between 9500 MPR and the service router in front of BSC/RNC
• b) 9500 MPR without ODU (MSS-8 or MSS-4 stand alone) provides the same level of feature
of a site aggregator box, grooming together different services (in this particular case E1 TDM)
into the common Ethernet layer.
