E1 Attachment for 4FTR and LCPU
As a rule one of the three following enabling variations is used:
Variation 1: Transmission Using Non-transparent Systems
The signal channel 0 (ZK0) of DVS-21 is transferred in the multiplexer (e.g.
XMP1) to e.g. signal channel 16 (ZK16).
Frame recognition of the DVS-21 is not transferred with it. The transmission
technology uses its own frame recognition.
For the DVS-21 the transfer is virtually transparent.
Variation 1: Signal channel 0 (DVS-21) transferred to channel 16 (PDH-MUX)
Variation 2: Transmission Using Non-transparent Systems
To transmit the control data, now the ZK16 of the DVS-21 is directly used.
ZK0 and hence the frame recognition of the DVS-21 is not transferred with it.
As in variation 1 the transmission technology uses its own frames.
Use of the signal channels is not necessary.
Variation 2: Channel 16 of the (DVS-21) is used as signalling channel
Variation 3: Transmission Using Transparent Systems
The 32 PCM channels of the E1 attachment of the DVS-21 are forwarded
transparently without being altered (e.g. radio relay, Modem, MS1/4, ...).
The use of ZK0 or ZK16 to signal is arbitrary.
Variation 3: Transparent transmission using radio relay system
