The MXK uplink cards enable operators to offer superior high-bandwidth services in a variety of network designs. The cards currently support two configurations: (1) 2 x 10 Gig + 8 x 1 Gig Ethernet ports and (2) 8 x 1 Gig Ethernet ports. Both fiber and copper SFPs are supported.
In addition, the MXK uplink cards provide full card and network redundancy by supporting an active card and backup standby in the same chassis. If a card or network failover occurs, the standby card will take over instantly, without dropping any voice calls. The cards also support link aggregation and the EAPS ring protocol, for additional network resiliency options.
