IMG 1010 - Network Timing

Before connecting the IMG 1010 to a network, it must be synchronized to a T1/E1 loop timing source such as a T1 or E1 DS-1. The IMG 1010 will accept up to four separate clock sources connected to various interfaces on the rear of the unit. The IMG 1010 - Timing Synchronization Priority List object defines the priority the IMG 1010 uses when selecting a clock source to sync to. Once the timing sources are connected, the Timing Synchronization Priority List determines which source gets highest priority, 2nd highest priority, and so forth to lowest priority. To create the Timing Synchronization Priority List, right click on the IMG Name object and select New Timing Synchronization Priority List. Below is an explanation of each of the timing references. The Pinouts of the RJ48 connectors are shown in IMG 1010 - RJ 48 Connector Pinouts.

The IMG 1010 cannot time off an atomic clock or similar. The TDM inputs on the rear of the unit will only accept a loop timing clock source from a T1, E1, or DS3.
