The WBS24 has two types of interfaces: wire and wireless. The wire interface is classified
into the interface that inter-works with the system and the interface that inter-works with
the LAN. The wireless interface inter-works with air section and meets the IEEE802.11b
standard.
Wire Interface Inter-Working With the System
This interface is connected with 4WLI by Digital Adapter Subscriber Loops(DASL), which
enables digital transmittance of 144 kbps(2B+1D). One WBS24 supports two DASL lines
and one DASL line provides two voice channels. One WBS24 can support a total of four
voice channels simultaneously. Also, D channel data for making a voice call are transferred
or received through the DASL line and its transfer rate is 16 kbps. This interface serves as a
voice path that creates or maintains a speech channel by forwarding or receiving the voice
packets exchanged with wireless interface to or from the system.
Wire Interface Inter-Working With the LAN
This interface is 10/100BASE-T and an Ethernet RJ-45 interface that meets the IEEE 802.3
standard. This is a path that transfers the data transferred or received through the wireless
interface to the LAN and processes required data transfer or receipt such as Internet access
except for voices.
