Installation Procedures This section provides detailed instructions for completing the steps in the
installation procedure illustrated earlier in Figure 3.
Step 1 (Optional): Install
the Optional Modules in
the Unit
This section tells you how to install the optional modules in the PathBuilder
S330/S310 chassis.
The PathBuilder S330/S310 supports three optional modules:
n CBR module—a board consisting of one V.35/RS-366/RS-449/RS-530/X.21
interface and three T1-DSX or E1 interfaces (one T1-DSX or E1 interface for the
PathBuilder S310). It services traffic generated by your existing PBXs, channels,
T1/E1 multiplexers, CSU/DSUs, and video conferencing devices. Install the CBR
module in expansion slot 7. Figure 6 shows the CBR module connections.
