Instruction manual

8
Timing – Port 1 Only, Switch 7: TNE1500-P Only
Timing refers to the clock source for T1 transmission links.
 Local – Local clock source refers to timing derived from an oscillator onboard the
TNE1500-P.
 Loop – Loop clock source refers to timing derived from an intermediate device.
The TNE1500-S determines T1 timing via communication with its partner T1 provider
unit.
Connect the T1 Line
Procedure
To establish a T1 connection:
1. Plug the T1 cable into the T1 RJ45 port on the back of the TNE1500.
2. Verify the connection: the T1 link LED on the front of the TNE1500 will pulse green
to indicate the connection is established and operational.
If you are using a shielded T1 cable for your network connection, it must be grounded
through pins 3, 6, 7 and 8.
