WAN Service Node

Y-Cable Redundancy

The WAN Service Node provides another form of ESP redundancy protection through the use of Y-cables. With Y-cables, the ESP ATM NIC can be connected to two BXM cards or two BXM ports, as shown in Figure 8-7. This prevents the failure of a BXM card or port from disabling the ESP.
