Product name : GSM E1 Multi-Channel Gateway
Item : GN-AD300W
Details :
This Gateway provide an all in one wireless solution. The other end equips

with GSM 850/900/1800/1900 band and CDMA 800/1900 band access combinations.The

interface of the network side is E1 Digital Interface with ISDN-

PRI/SS7/V5.2/CAS R2 Signaling.
The interface on the user side is 16 x GSM/CDMA Wireless links.

It is a device with advanced moduled design, embedded with real
time operation system, seamless switch, high reliable and low
power consumption, flexible configed with variable applications
for cost saving. It is an ideal choice for terminating long distance

traffic to the mobile networks. No LAND LINES REQUIRED!!!
Integrates the E1 port to the GSM/CDMA network to provide 16 GSM/CDMA wireless

for mobile communications;
The interface of the network side is E1 Digital Interface with ISDN-

PRI/SS7/V5/CAS R2 singalling
The interface on the user side is 16 x GSM/CDMA Wireless links.
The device is also embedded with 24 VOIP channel as internal switch.
Easy configuration through RS 232 console/IP port access
Compact, 16 GSM wireless terminals in a 1U rack size chassis.
Tested to work with Cisco/Quintum VoIP Servers (and many others).
Integrated 64ms E1, Echo-Canceller to eliminate any echoes arising out of

network delays.
128ms echo canceller - optional extra. Lower cost - resulting from complete,
GSM wireless to E1 integration.
