The connection of the base stations to the BS 8-15 connector of the extension card
(see figure 8.3) can be done in two different ways. One way is to solder the 25 pole male
sub D connector to the base station cables (see 1.), the other way is buying a BS-DCU
connection cable LBB 6721/02 (see 2.).
1. Soldering the wires to a 25-pole male sub D connector according the pin
configuration in Table 8.1 and plug the connector on the BS 8-15 connector of the
extension card (see figure 8.3).
Table 8.1 Base station to DCU connector
2. Connect the optional BS-DCU connection cable to the BS 8-15 connector of the
extension card (see figure 8.3) and the wires via a terminal strip, located near by a
PABX, to the base stations (see figure 8.5). For wiring of the BS-DCU connection
cable LBB 6721/02 see Table 8.2.
