Cisco Vwic-2t1/e1-ran = 2 Multiflex Trunk Voice / Wan Ip Ran

The Cisco IP-based RAN Optimization Solution allows for a variety of backhaul transport media, enabling higher-capacity and lower-cost alternative RAN transport networks for GSM/GPRS/EDGE and UMTS/HSDPA traffic. Higher-speed broadband backhaul media such as DSL and Metro Ethernet are ideally suited for transport of UMTS circuit-switched data and HSDPA data traffic.

The Cisco T1/E1 RAN VWIC terminates UMTS or HSDPA Iub T1/E1s or multiple UMTS or HSDPA Iub T1/E1s as an IMA interface, and processes the data traffic for IP-based optimization and offload onto an alternative RAN backhaul network such as DSL, IEEE 802.16, or Metro Ethernet.

The Cisco T1/E1 RAN VWIC is designed to meet the emerging PWE3 standards for TDM Circuit Emulation over Pseudowires (CEoP) and ATM over Pseudowires (ATMoP). For CEoP, the Cisco T1/E1 RAN VWIC supports standards-compliant Circuit Emulation Services over Packet Switched Network (CESoPSN) and Structure-Agnostic Transport over Packet (SAToP) transport. By enabling CEoP, the Cisco T1/E1 RAN VWIC regards the data as an arbitrary bit stream with no predefined format or structure. All data bits are simply transported to a defined destination encapsulated in MPLS packets. For ATMoP, the Cisco T1/E1 RAN VWIC supports standards-compliant ATM-over-MPLS and ATM-over-L2TPv3 transport. The ATMoP service allows mobile operators to effectively manage the bandwidth at the edges of their transport network while implementing value-added Layer 3 services. Advanced traffic management features, such as per-PVC traffic shaping, can also be used to help ensure that traffic from one customer does not affect traffic from another
