4.11.17 BCU Pin Assignment
The B-Channel-Unit (BCU) enables the VOIP/IP connectivity of the NovaTec
S20. The BCU
includes the vocoder and the elastic buffer for the voice compression and Jitter compensation
for the IP Package trip. BCU handels the RTP and RTCP for the VOIP applications.
The BCU is available in 4 variants:
1F7000 -> BCU-4 with 4x vocoder
1F7001 -> BCU-8 with 8x vocoder
1F7002 -> BCU-16 with 16x vocoder
1F7003 -> BCU-32 with 32x vocoder
The Moduls are not distinguishable from the front. If the BCU is removed from the System
a sticker can be found on the connectors to the backplane with Model number, hereby the
individual variants of the BCU can be differentiated or if a connection is made via the
Trace-Info-Client this can be also be used for distinguishing between models. The BCU
has a Ethernet connection, two status LED and a connection of a GPS antenna and a Sub-
Modul-Place for the GPS-Receiver.
