Connections for External Timing Cables
An external timing cable provides a connection from an external synchronization source, such as a building
integrated timing supply (BITS) or synchronization supply unit (SSU), to a SmartEdge 1200 system. Each
cable consists of two individually shielded, twisted wire pairs: one pair for the synchronization input and
another pair for the synchronization output.
Two connections are possible: one from a primary source and one from a secondary source. Either
connection can provide timing for the entire chassis (input), regardless of the configuration of the controller
cards. See Figure 4-24 for the location of the connectors for these cables.
Note The XCRP and XCRP3 Controller cards can both receive and transmit timing data; however,
the XCRP4 can receive timing data only. However, the SmartEdge OS does not support the
transmission of timing data to another SmartEdge router or any other external equipment.
Note An adapter, available as an option, provides wire wrap pins to allow you to attach a cable
without a connector.
Note Support for the other ports depends on the release of the SmartEdge OS.
