T1/E1 Clocking
Depending on the configuration of the T1/E1 boards and span for your AltiWare
system(s), the System Clock Master setup should be set according to the follow
conditions:
•
If all of the T1/E1 boards are connected to a carrier’s switch, the System Clock
Master check box must not be checked for any of the T1/E1 boards.
•
If two AltiWare systems are connected back-to-back with a T1/E1 span, the System
Clock Master check box must be checked for only one of the T1/E1 boards.
•
If two T1/E1 boards in the same AltiWare system are connected back-to-back with
a T1/E1 span, the System Clock Master check box must be checked for the T1/E1
board that has not been designated by the CT-Bus setting as the system’s master
clock to drive the CT-Bus.
Important:
For all back-to-back cases, the CT-Bus Clock Configuration should be set to
“Manual,” and the board that is connected to the board configured as the
back-to-back clock master must be designated at the CT-Bus master.
Setting up Channels on the Triton T1/E1 Board
This section discusses setting up T1 CAS, T1 PRI, E1 CAS, or E1 PRI channels on the
Triton T1/E1 board.
Click the Protocol button in the T1 or E1 configuration dialog box (see Figure 8 on
page 130) to open the Protocol Configuration window, shown below. The Triton T1/
E1 Board can be configured to either CAS or PRI through the configuration options in the
window.
The CH -> Type list on the left side of the window displays the channel types.
Note:
In a tie-trunk configuration, set the trunks to “Out of Service” before changing the
trunk type from T1 to PRI or vice versa. Otherwise, the system will generate
garbage call records to your internal or external logger service. See “Setting
General Trunk Attributes” on page 150 for details.
System Clock Master
You can set the System Clock Master if you have a back-
to-back configuration and you want this span to be the
master clock to the system. (Only one clock master should
be selected in a back-to-back system.) See the following
section on T1/E1 clocking.
