Cable an HFC Connector Module or SIM

This section describes how to connect the four downstream and four upstream F-connector
ports of an HFC Connector Module or SIM. This section also describes how to connect the
two Fast Ethernet ports on an HFC Connector Module or SIM.

Cable the F-connector Ports

Each DOCSIS Module, and its corresponding rear HFC Connector Module or SIM, support a
total of four downstream interfaces, where one interface is assigned to each physical
downstream port. Each DOCSIS Module supports a total of 8 or 16 upstream interfaces
(depending on the DOCSIS Module model), which can be allocated to any of the four physical
upstream ports (US0 through US3). Figure 34 illustrates an example where the number of
interfaces allocated on each port is five, three, seven, and one. You should consider the
assignment of a node to a port and the allocation of upstream interfaces to upstream ports
prior to connecting the coaxial cables from the cable plant to the HFC Connector Module or
SIM.

Figure 34: Example of Allocation of Multiple Interfaces Per Port

The following ports on the SIM are not used:
! Fast Ethernet ports Eth0-B and Eth1-B
! Upstream F-connectors US4 through US7
! Ports DSR-IN and DSR-OUT
Prior to inserting a coaxial cable into any of the module
F-connectors, ensure that the cable meets the
requirements provided in "Coaxial Cable Requirements"
on page 75.
