CONFIGURATION
Read Chapter 3. CHECKLISTS
FOR
INITIAL START-UP
AND
CONFIGURATION . When adding a
CDM-750 or CDM-760 Advanced High Speed Trunking Modem to an operating 1:N system:
•
Make sure the modem uses only the CRS-505 Redundant Modem Interface (RMI).
•
Make sure the new modem does not interfere with existing traffic.
•
Make sure the Traffic Modems have the same traffic data types within the same CRS-500
1:N Redundancy System.
•
Make sure the cabling is correct.
•
Perform the power-up sequence correctly (see Section 5.5 Power Connections ).
•
Make sure there is no system contention from the modem Tx carrier.
•
Four types of cables are used to connect the CRS-500 and the modems:
o
Control Cables
o
Ethernet System Communication Cables
o
Traffic Data Cables
o
IF Cables
•
The tables provided in Section 5.1.1 Configuration and Cable Connections Summary
specify the respective cables needed for each modem and data type.
•
Figures provided in the chapter sections that follow show examples of the various 1:N
cable connections between the CRS-500 and the modems. For clarity, these figures
typically show a limited number of installed Traffic Modems.
