Installation
Important! When installing the RRCU, be sure to put the card in the slot before attaching the
data cables. Detach the data cable before removing an RRCU1A. Failure to do so
may cause interference with other data highways.
6. Insert the cards
• On the Master side, the RRCU card may be installed in Slots 1~8.
• On the Slave side, the RRCU card may be installed in Slots 1~10.
• The RRCU1A is a non-timeslot card and can be installed in slots normally left vacant
adjacent to digital trunk cards.
7. Connect the data cables
• At the Base Cabinet, attach an BDCL1A data cable from the data cable connector at the left
of the cabinet to Connector M1 or M2 on the RRCU card. (Cables are provided according to
the connectors on the RRCU card to which they are attached, see Table 4-13.)
• The cabinet connected to M1 in the
base emerges on connector S1 of the
RRCU1A at the Remote Expansion
Cabinet.
• The cabinet connected to connector
M2 of the RRCU in the base emerges
on connector S2 of the RRCU1A at
the Remote Expansion Cabinet. See
Figure 4-41.
• Route the cable through the
cabinet according to Figure
4-40.
• Coil the excess and attach it to
the grommet on the cabinet
wall with a tie wrap. Be careful
not to bind the cable tightly.
• Close the data cable doors.
