used in China, Europe, the Commonwealth of Nations, and other countries.
1.3.2 Ethernet Cable
Introduction
There are two types of Ethernet cables: straight through cable and crossover cable.
Straight through cable
The straight through cable is used to connect a terminal to the network. For example, you
can use the straight through cable to connect the maintenance terminal or the network
management workstation to the network.
Crossover cable
The crossover cable is used to connect two terminals. For example, you can use the
crossover cable to connect the maintenance terminal to the maintenance network
interface.

1.4.2 Networking in Video Firewall Mode
The video firewall mode is used as a simple way to realize the traversal between public and
private networks. You can connect the MCU to different networks through different network
interfaces. In this case, video terminals in different networks can join the same conference.
Figure 1-9 shows the networking diagram in video firewall mode.

1.4.3 Cascading Networking
Cascading means that a master MCU is appended with some slave MCUs. Figure 1-10 shows
cascading networking. By using the cascading technology, you can greatly expand the
capacity of the videoconferencing system.
Figure 1-10 Cascading networking
The master and slave MCUs are determined when you define a cascading site.
The master and the slave MCUs join in a conference on another MCU as a single site.
Each master MCU can be appended with multiple slave MCUs, while each slave MCU
can be appended to only one master MCU.
MCUs are cascaded through IP lines.
Multi-Channel Cascading
During a single-channel-cascaded conference where only one channel is used between
cascaded MCUs, the following aspects are restricted:
Only one site from a slave MCU can be added to continuous presence.

Only the chair site can view the sites on the remote MCU. Ordinary sites can view only
the sites on the local MCU.
The MCU supports multi-channel cascading. By using several channels for cascaded
conferences, the MCU can send multiple channels of data streams to other cascaded MCUs,
removing the preceding restrictions on single-channel conferences. For example, in the
multi-channel conference as shown in Figure 1-10, videos of sites on MCU2, MCU3, and
MCU4 can be displayed in continuous presence on MCU1.
During a multi-channel-cascaded conference, the following aspects are restricted:
MCU1 cannot be an 8650C.
Multi-channel cascading is used for a and functions of continuous presence and site
selection.
A maximum of 32 channels can exist between master and slave MCUs in one
conference.
A maximum of three levels of multi-channel-cascaded MCUs is supported in
networking.
Sites located in different provinces cannot join a multi-channel-cascaded conference
simultaneously.
Line backup is not supported, that is, the mode in which active and backup sites exist is
not supported.
During a scheduled conference that contains cascaded sites, a slave MCU can be
cascaded to only one master MCU, but can be cascaded to by multiple slave MCUs.
The function of automatic rate reduction is not supported.
Automatically Scheduling a Cascaded Conference
You can manually add sites on different MCUs to create a multi-channel-cascaded conference.
Such conference can also be scheduled by the RM automatically in one of the following
situations:
During the defining of an ordinary conference, sites are assigned to difference MCUs, or
a site is not assigned to any MCUs and cannot be assigned to the same MCU as other
sites (the second situation occurs if, for example, sites using IP and E1 lines exist in a
conference, and the master MCU does not support the simultaneous access by sites using
different types of lines).
During a multi-level conference, sites in the upper-level or lower-level conferenence are
from different MCUs (see the conditions of automatic cascading for ordinary
conferences).
During an active conference, a site that is not from the master MCU is added (see the
conditions of automatic cascading for ordinary conferences).
During the SiteCall, sites using various types of lines exist and the master MCU does not
support the simultaneous access by sites using different types of lines.
1.4.4 Static NAT Networking
With static network address translation (NAT), the IP address of the GE0 network interface on
an MCU can be mapped to a public IP address. This approach enables terminals on different
private networks to access the same MCU, regardless of whether the terminals and the MCU
are located on the same private network. This approach is applicable to the situation where the
following conditions are all met: Many of the sites participating in a conference are not in the
city where the MCU is located; the sites in other cities are on private networks that can

connect to but cannot be connected by public networks; the MCU cannot be deployed for a
videoconferencing system over a public network.
Figure 1-11 shows static NAT networking.
Figure 1-11 Static NAT networking
The following aspects are restricted for static NAT networking:
The GK used in the networking must be an external GK.
The NAT devices must support static IP address mapping.
If the GK is on a private network, you must enable Q.931 routing, H.245 routing, and
NAT from the GK. In addition, you must use the private IP address of the GK when
registering the MCU to the GK.
A terminal that is on the same private network as the MCU cannot be registered with the
GK. Therefore, the terminal must use an IP address to attend a conference.
Multi-layer NAT is not supported.
1.4.5 H.460 Networking
H.460 is a series of extensions to the H.323 videoconferencing standard from the ITU.
Introduced in 2005, several of the extensions, including H.460.17, H.460.18 and H.460.19,
deal with firewall and NAT traversal.
Figure 1-12 shows the networking diagram in H.460 mode.
