Cross-Connects
All cards plug into a backplane, which carries a high-speed parallel bus to
provide the cross-connect and end-to-end circuit connectivity for traffic channels,
auxiliary data, NMS, and protection switching.
The backplane bus can operate in one of five user-programmable configurations,
NxE1 (2.048 Mbps), NxDS1 (1.544 Mbps), NxDS3 (44.736 Mbps), or NxSTM1/
OC3 (155.52 Mbps). In this way, a 9500 MXC Node can be configured to be an
NxE1, NxDS1, NxDS3, or NxSTM1/OC3 radio, or an Ethernet radio with or
without companion TDM traffic.
