Note
7 Line interface and synchronization
settings
During the commissioning procedure, you need to check and, if necessary,
change settings in the LIF Settings and Synchronization dialogue boxes.
7.1 Line interface settings
The contents of the LIF Settings dialogue box depends on the type of the
transmission unit, F(X)C E1/T1 or RRI.
7.1.1 LIF settings for F(X)C E1/T1 transmission units
Define E1/T1 LIF settings as follows:
1. Select the tab for the line interface you want (LIF 1 - LIF 4).
If the transmission unit type is FC (no cross-connection capability), the dialogue
box has only one tab, LIF 1.
2. Tick the ‘Interface in Use’ option.
3. Select the interface mode from the list. If you select ‘T1 100 ohm’,
additional settings appear in the dialogue box. See Step 5.
4. Tick the ‘CRC in Use’ option if this is defined at the BSC.
5. If you selected the ‘T1 100 ohm’ interface mode, you need to define the
TS0 fixed bits. TS0 fixed bits from 1 to 3 are reserved for CRC and frame
locking. Bits 4 to 8 are used for alarms and data transfer in national
connections.
