HFC Connector Module
The HFC Connector Module contains a 6 U (267 mm) x 80 mm card with an 8 HP (40 mm),
double-wide rear panel. The module installs from the rear of the chassis and is
hot-swappable.
The HFC Connector Module has two RJ-45 Ethernet connectors carrying IP data to and from
the network-side interface. The module also has four downstream F-connectors and four
upstream F-connectors for routing traffic to and from the HFC network (see Figure 18 on
page 51).
The HFC Connector Modules are located on the opposite side of the midplane from the
DOCSIS Modules. These modules can occupy slots 1 through 4 and 10 through 13. There is
one HFC Connector Module for each DOCSIS Module.
The HFC Connector Module receives downstream IP data from the 100Base-T Ethernet cables
coming from the NIC Access Module. IP data is then passed to the DOCSIS Module for
processing into DOCSIS frames, then into an MPEG stream. The MPEG stream is modulated
onto the RF carrier signal and routed back to the HFC Connector Module (through the
midplane) for downstream distribution through the F-connectors to the HFC network.
Upstream data follows the path in reverse order, starting with data coming into the upstream
F-connectors. Figure 19 on page 52 shows this data flow.
Table 24 summarizes the definitions of the Fast Ethernet LEDs on the HFC Connector
Module. Figure 18 on page 51 shows the HFC Connector Module rear panel.
Table 23: HFC Connector Module Fast Ethernet LEDs
If a NIC Module is used in a version 2 chassis, you must use
a SIM opposite each DOCSIS Module to provide the
Ethernet connectivity between a DOCSIS Module and a
NIC Module (through the midplane). You must not use an
HFC Connector Module in this configuration.
