Transmission delay

One-way transmission delay

The following tables list the worst-case maximum one-way transmission delay (microseconds) between Alcatel-Lucent 1850 TSS-5 interfaces. Alcatel-Lucent 1850 TSS-5 is a hybrid box combining features of an add/drop mux (ADM) and a digital cross-connection system (DCS). Consequently the specified maximum delay is a summation of the requirements for these two functions. Actual transmission delays are likely to be less than specified.
