Figure 5 Remote Site Traffic Flow Scenario
Central Office Site Traffic Flow Scenario
Unlike the remote site, in the central office, traffic from each IMA line card of the IES is directly
forwarded to the MSC and the connected Ethernet (IP) network. The following figure shows an
example.
In the central office, your IES should have an Ethernet connection to a backbone network. The IMA
converts ATM cells coming from remote sites to Ethernet frames. Depending on your configuration,
the IMA also converts traffic from double-tagged PVCs to either single-tagged or double-tagged
VLAN frames. The MSC receives the frames and then forwards the frames to the Ethernet network
(backbone).
