[c-nsp] BITS interface on ME-3600X

[Martin T]

Hi,

Cisco ME-3600X switches support RJ45 BITS(Building Integrated Timing
Source) interface which can be used for sending and receiving the E1 or T1
timing signals. As I understand, timing signals in case of SDH/SONET are
needed in each node to keep the transmit and receive rates unified all over
the network. In which scenario would somebody want to use ME-3600X for
providing this clock signal? In addition, why would one want to receive
E1/T1 timing signal on an Ethernet switch?


regards,
Martin
