1. Introduction
With the G.hn Bridge G4201TM you can easily set up a local
network over existing telephone cables.
The modems are "multipoint" capable. Up to 16 devices
can be set up on a 2-wire telephone line. Each modem
communicates directly with all others in the G.hn network
("peer-to-peer").
The G4201TM, G4202T, G4202TCP (with PoE/PoE+) and
G4204T-W (with Wi-Fi) models are compatible with each
other and can be combined in the network as desired.
Any type of cable can be used for data transmission –both
twisted pair and non-twisted pair, the net bandwidth is up
to approx. 1500 Mbit/s, depending on the cable length. This
bandwidth is shared between all connected modems.
The G4201TM Bridge is also suitable for forwarding the
fiber optic connection from the ONT to the router via an
existing telephone line in the single-family home. Two
modems are required.

6. Compatible modems
Models G4201TM (1x GE), G4202T (2x GE + analog phone), G4202TCP (2x GE with PoE/PoE+) and G4204T-W (4x GE and Wi-
Fi) are compatible with each other, they can be combined in the network as desired.
7. Use for forwarding a fiber optic connection (ONT -> router)
For devices from serial no. R3A0266847:
By default, DHCP Client is enabled, which allows the modem to obtain an IP address from the DHCP server. Disable the DHCP
client in the modem before connecting to the ONT. To do this, log on to the modem's web interface (see point 13), set the IP
address to "Fixed" under the "IP" menu item and enter an IP from a local range (e.g. 192.168.10.252, netmask
255.255.255.0).
8. Use for home networking (local network after the router)
All types of wiring are possible: "point-to-point", "star-shaped" and "in series", even the combinations thereof.
"Point-to-Point":
"In line"

"Star-shaped"
9. Connection type and pin assignment on the device (RJ11 plug)
The G.hn connection is made via a pair of wires (connection type SISO = G.hn profile "PHONE 200MHz").
10. Installation Notes
The cable cores can be placed straight or crossed.
Maximum range of the G.hn connection depends on the type of cable used and the environment. Typical values for a
0.5 mm twisted-pair cable: Connection possible up to approx. 600m, max. bandwidth of 1500 Mbit/s –up to approx.
100m.
In the web interface of each modem, the negotiated bandwidths can be queried to all other G.hn bridges in the network
(see point 15).
Further information and recommendations can be found on our homepage www.gigacopper.net under the heading
Support.
11. IP address
The modems do not require IP addresses from the local network segment during operation, because they mediate data
traffic via the MAC addresses.
Factory settings for devices up to serial no. R3A0266846:
IPv4 DHCP client is deactivated, the modem does not obtain an IP address from the local DHCP server. If desired, a static
IP address can be configured or the DHCP client can be activated (menu "IP" in the web interface)
Primary IP address: 192.168.10.253
Factory settings for devices from serial no. R3A0266847:
IPv4 DHCP client is enabled, the modem obtains an IP address from the local DHCP server
Secondary IP address: 192.168.10.253
12. Administration
Pin assignment SISO

13. Use of Multicast IP-TV
For the transmission of Multicast IP-TV (e.g. Telekom MagentaTV)
in the network, "IGMP snooping" must be activated in the multicast
configuration.
14. Notching, compatibility with DSL/VDSL
Login to the Web Interface
For devices up to serial no. R3A0266846:
Connect your computer to the G.hn modem through the GE port.
Assign your computer a fixed IP address,
e.g. 192.168.10.100 (netmask 255.255.255.0).
Open a web browser and connect to 192.168.10.253.
Log in with the default password: paterna
For devices from Serial No. R3A0266847:
On your computer, open a web browser and connect to the IP
address of the modem.
To do this, use the IP address assigned by the local DHCP server.
Log in with the default password: paterna
The connection via the second IP address (192.168.10.253) is
possible even if the modem has not yet received an IP address from
the local DHCP server. Procedure as above.
The G.hn modems can also be used in parallel with DSL/VDSL
connections with unshielded telephone cables and via pairs of a
common cable.
In the case of DSL and VDSL50, the G.hn modems usually do not require
any additional settings.
For compatibility with VDSL100 (profile 17a) and VDSL250 (profile 35b),
the G.hn level in the range 2-17MHz and 2-30MHz must be reduced by
10dB. The setting must be configured in each modem (G.hn spectrum).

15. Query of negotiated bandwidths
The bandwidths negotiated from the G.hn modem to all other G.hn bridges in the network can be queried via the web
interface. The reported values are gross data transfer rates at the physical layer (PHY). The transfer speed at the application
level is about 15-20% lower.
16. VLAN usage in the network
The devices are compatible with VLANs according to the 802.1Q standard.
The VLAN tags are forwarded transparently. External Ethernet switches must be used for the formation of VLANs.
