Data Sheet
Transparent Mode
Setting this bit enables the transparent mode:
In transmit direction bit 8 of every FS/DL time slot from the system
internal highway (XDI) is inserted in the F-bit position of the outgoing
frame. Internal framing generation, insertion of CRC and DL data is
disabled.
In receive direction the framing bit is also forwarded to RDO and
inserted into the FS/DL time slot. Bit RDCF (bit 1 of FS/DL time slot)
indicates a DL bit.
Transmit Remote Alarm (Yellow Alarm)
If high, remote alarm is sent via PCM route. Clearing the bit removes
the remote alarm pattern. Remote alarm indication depends on the
multiframe structure as follows:
F4:
F12: FMR0.SRAF = 0: bit2 = 0 in every speech channel
ESF: FMR0.SRAF = 0:
F72: bit2 = 0 in every speech channel
Select Sync Conditions
Loss of Frame Alignment (FRS0.LFA or opt. FRS0.LMFA) is declared
if
00 = 2 out of 4 framing bits
01 = 2 out of 5 framing bits
10 = 2 out of 6 framing bits in F4/12/72 format
10 = 2 out of 6 framing bits per multiframe period in ESF format
11 = 4 consecutive multiframe pattern in ESF format
are incorrect. It depends on the selected multiframe format and
optionally on bit FMR2.SSP which framing bits are observed:
F4:
F12, F72: SSP = 0: FT bits
ESF:
bit2 = 0 in every speech channel
FMR0.SRAF = 1: FS-bit of frame 12 is forced to ‘1’
pattern ‘1111111100000000 11111111000…’
