2.0 Access Networks Based on V5
Interface
The V5 interface has become important in the
industry due to ease of deployment in various
network scenarios. A variety of network equipment
supporting V5 interface are being developed, ranging
from a static subscriber multiplexer based on the
V5.1 interface, to digital line concentrators or
Wireless Local Loops (WLL) based on the V5.2
interface. Figure 1 shows a network scenario based
on the V5 protocol.
The V5 interface specifications are applicable to both
wireline and wireless access systems. In a typical
WLL the interface between the LE and the BSC is
implemented using an E1 interface. Implementing
the V5 interface on this E1 link between the BSC and
LE cuts costs by eliminating the need for exchanging
end equipment to multiplex the analog ports onto the
digital link.
The V5 interface is independent of the multiple
access technique (such as TDMA or CDMA) used in
air interface between the base stations and the wall
sets (fixed terminals). Figure 2 shows a block
diagram of the hardware architecture of a typical
access network with V5 interface. Details are
addressed in the implementation.
