Chapter 3 Installing the TimeCreator 1000
Making Signal Connections
To connect a TimeCreator 1000 root server to a subtending server, install a shielded
twisted pair RJ-45 cable, CAT5E or better, from the root server's rear panel DTI
connector to the subtending server's client input port (port A or port B, when
optioned as 'client').
If the root server in a DTI network with subtending servers is set to user mode to
utilize root server recovery, a connection should be made from the root server port
12 to a subtending server port 1. This enables root server recovery, in an orderly
manner, from any outages affecting the root server
The connector pinouts are listed in Table 3-3.
Figure 3-4. Rear Panel DTI Links
Note: Continuing improvements to the design of the TimeCreator
1000 have lowered the level of emissions. UTP cable can be used for
DTI links with TimeCreator 1000 chassis revisions E or greater
(revision is on label on bottom of shelf).
