Are there any specific concerns when using a DS1 carried over SONET to time equipment such as a switch remote or DLC?

A. Yes. The major concern is to make sure all the equipment is synchronous to each other to prevent pointer adjustments. For example should you have an OC-N that goes through multiple carries, a LAN Emulation Client (LEC) and interexchange carrier (IXC) for example, and one of clock is a stratum 1 while the other is being timed from some stratum 3 holdover source, you will have pointer adjustments that will translate into DS1 timing jitter.
