4.1 Overview
The transmission link between ZXSDR BS8802 C100 and BSC uses IP packets.
Therefore, ZXSDR BS8802 C100 networking can make full use of the rich IP network
resources. In this way, the investment on dedicated circuit transmission network is saved.
The following part describes three networking modes using different transmission
resources.
4.2 Existing Transmission Resource
If there are idle transmission timeslots between target coverage area and BSC, the
networking mode shown in
can be used to make full use of existing transmission
resources. In actual practice, as E1 transmission link always exists between coverage
site and BSC, use a pair of G.703-V.35 protocol converter to convert IP signals and E1
signals.
Figure 4-1 Existing Transmission Resource
Advantage: It guarantees the transmission quality and utilizes the operator's existing
resources.
Disadvantage: It does not make use of the advantage of IP transmission, and signal
conversion introduces delay loss.
