Functional Description
The TimeCreator 1000 accepts one GPS input and two DTI inputs for system
reference and it allows you to provision the DTI input reference priority. When a
GPS or DTI reference is qualified as the system reference, the server uses the
qualified reference to acquire the system’s frequency, DTI timestamp, and TOD
alignment.
The TimeCreator 1000 rear panel has ten DTI client links (six DTI client links for
8-port option) and two client/server links. Client links connect to an M-CMTS Core,
Upstream receiver, Edge QAM, or DTI server. Server links allow a subtending
server to receive time and frequency signals from a DTI root server. There are also
two T1/E1 BITS frequency inputs.

diagram of the IMC card, and Figure 1-7 is a block diagram of the IOC card.
Note: The BITS connectors are not functional in this release.
