The GXW42XX V2 high-density FXS gateway series enables
businesses of all sizes to create a cost-e󰀨ective hybrid IP
and analog telephone system that o󰀨ers the benets of VoIP
communications and takes advantage of Gigabit speeds
while preserving investment on existing analog phones, fax
machines and legacy PBX systems. The GXW42XX V2 se-
ries includes 16/24/32/48 FXS ports, a Gigabit network port
and features broad interoperability with most service provid-
ers, soft-switches and SIP-based environments.

see section “Telecom Port Instalation “ for details).
2. Insert the Ethernet cable into the LAN port of GXW42XX
V2 and connect the other end of the Ethernet cable to an
uplink port (a router, a modem, etc.).

Telecom Port Installation
GXW42XX V2 use 50-pins RJ21 Telco Amphenol port as
alternative interface (For GXW4248 V2, telco port is manda-
tory) for connection to analog devices, such as analog tele-
phone or fax machine.
When installing the telco
port, a common RJ21 Telco
Amphenol 50 pin 25 pair
cable is needed (included in
the GXW4248 V2 package
only). You can connect the
cable to a RJ11 patch panel,
which could provide a better
cable management in most
scenarios.
Below is a picture of RJ11 female port patch panel.
Following table shows the correspondent relation between
the No. of each Telco cable’s RJ11 crystal head and the
real FXS port number of GXW42XX V2.
Note: Row “Right” indicates the righthand side telco port,
when you facing the back panel of GXW42XX V2, and
“Left” is the left telco port.
