(ONS
15454 SDH only) The RAN_SVC card performs circuit emulation and optimization on traffic from 3GPP RAN nodes and provides IP based backhaul of the optimized traffic to other peer nodes. The optimized traffic is received by the RAN_SVC card from peer cell site routers on VC12 circuits from the Cisco ONS 15454 SDH cross connect card or from native GE ports on the RAN_SVC card.
Optimized traffic may be received on the ONS node over a variety of rate interfaces higher than VC12,
such as STM1 through STM64 on the ONS 15454 SDH. The data is then reconstructed by the RAN_SVC card onto VC12 circuits and sent back through the cross-connect card. The reconstructed traffic is externally delivered to the 3GPP RAN nodes over E1 and STM-1 interfaces.
