Gen 3 Site Controller System Manual Chapter 4 Installation
Intercabling Connections
The Telco interface should have been installed according to the
Pre-installation chapter.
Note: The equipment can be installed and tested without the Telco T1/E1
present. The T1/E1 must be connected for proper operation of the
site.
Note: Some modular cables have a ridge along one side of the cable for
purposes of alignment with the connector.
Note: The SmartJack is capable of passing -48V Telco power through to
the site controller. For operation, iDEN does not require this power.
If -48V is present on the network connection to the site controller,
the SmartJack is incorrectly configured. Contact the service provider
immediately to correct this situation. The SmartJack switch should
be set so that -48V power does not pass through to the site controller.
If this cable is locally manufactured, crimp the 8-pin connectors as shown in
Figure 4-23. The wires should be routed straight through. Make sure that the
conductor color is the same at both ends for each conductor of the cable.
