Table 7. DIRECT MAPPING TABLE FOR TLIB
When using connection to the ISDN network, an RJ45 type connector on the ISDN
interface cards (2BRI, PRI, STIB) and not the CHAMP connector on the MBU is
used. See Figure 33.
Figure 33. ISDN LINE WIRING
4.7.6 Clock Control Cable Wiring
When two or more Digital CO/ISDN interface boards (2BRI, PRI or STIB) are
installed in the system, the clock control cable should be installed for system
synchronisation with the ISDN network. The connection method is shown in Figure
34.
Basically the system uses the clock output from the board that is installed in slot #3 as
a master clock.
