Synchronization Distribution (DCT1900 Mobility Configuration Only)

A DCT1900 system can provide synchronization to three other DCT1900 systems if it is the synchronization master or is connected to a synchronization master (only two levels are allowed, see also Figure 2–1). If PWT air interface (frame) synchronization is required between DCT1900 systems, then the DCT1900 systems have to be connected to each other by means of an external sync cable. The maximum external sync cable length is .8 mile (this value depends on the core diameter of the cable, refer to Chapter 18, Paragraph 18.2 of the Installation Instructions for more details).
