Installing ISDN in a Double Cabinet with the ISDN in
the Slave
1. Before beginning ISDN installation, perform the “ISDN Function Reset”
command (FF1 9# 1# 1#). This command must be issued before the ISDN
can be installed properly.
2. Check SW4 on the SCC-B card. Be sure it is set to “Mode B.” (See Step 2
on page 2-14.)
3. Install the Sync Unit in the master cabinet as described in Steps 3 and 4 on
pages 2-15 and 2-15.
4. Install an MDF card in the slave cabinet. (See Step 5 on page 2-17.)
5. Set Switch 1 on the ISDN card. (See Step 6 on page 2-18.)
6. Install an ISDN card in the “EC/TRK” slot of the slave cabinet.
7. Connect the Sync Cable from CN1 on the Sync Unit to CN5 on the ISDN
card (Figure 2-9).
Note: Part Number VB-43564 is used for the Sync Cable when an ISDN
is installed only in the slave cabinet of a two-cabinet system.
8. At the slave cabinet, connect the cable attached to CN3 on the MDF card to
CN3 on the ISDN card (Figure 2-8).
9. Using an RJ48 cable, connect CN1 of the MDF card to the CSU. (See
Figure 2-7 for RJ48 pinouts.)
