Alcatel 7390
LMDS Exchange Base Station
The Alcatel 7390 LMDS point-to-multipoint broadband wireless access solution
provides ISDN Basic Rate Interface (BRI) service in combination with the Alcatel
7390 LMDS Exchange Base Station (XBS) access node. The 7390 XBS provides the
v5.2 links for the switch, and can be collocated with the Alcatel 7390 Digital
Base Station (DBS) or located at another site.
Highly scalable and fully managed as part of a multiservice solution, Alcatel
7390 LMDS products can be rapidly deployed to provide a powerful, cost-effective
access solution for the first mile delivery of a wide range of data, Internet,
voice and video services.
A variety of interfaces for the end user
At the customer premises, the Alcatel 7390 LMDS Network Termination (NT)
provides two 10Base-T ports, and a variety of other interfaces, such as four
a2B+D port U interfaces, available in either ITU-T 2B1Q or German 4B3T
standards. Up to four ISDN network terminations can then be connected to the
7390 NT to provide S/T and/or analog interfaces to ISDN customers at the Alcatel
7390 LMDS base station site.
On the LMDS Air interface, each ISDN BRI uses one time slot (TS) per B
channel. For the D channels, one TS is reserved for concatenated signaling per
Alcatel 7390 NT, for up to four ISDN BRIs.
An Alcatel 7390 XBS can be connected to up to four 7390 DBSs, and up to four
XBSs can be connected to one DBS. On one side, the XBS provides four E1 links
toward the network, compliant with the v5.2 access protocol, and four E1 links
toward up to four collocated or remotely located DBSs on the other. Up to four
E1 links can be used for conveying ISDN BRIs from one single 7390 DBS.
Operation and maintenance
Operation and maintenance for the Alcatel 7390 XBS is provided through a
local operation and maintenance station (OMS) running on a PC through Windows
NT. The OMS can be accessed locally or remotely, in both cases through an X.25
network. The remote OMS is able to manage up to 14 XBSs.
