Procedure
The connection between the GWBB subboard and the PRI cable box needs two
DB-36—DB-68 cables that connect to DB-1 and DB-2 respectively on the rear panel of the
PRI cable box. Each PRI cable box supports a maximum of 16-port PRI access. The ports can
be classified into two sets, namely, DB-1 and DB-2, corresponding to that of the DB-68 ports
in the rear panel of the PRI cable box.
The following uses the PRI cable box (75-ohm unbalanced) as an example to illustrate the
16-port PRI access.
Step 1
Connect the DB-36 connector and the DB-68 connector of the DB-36—DB-68 cable to the
DB-36 port in the front panel of the ISDN board and the DB-68 port in the rear panel of the
PRI cable box respectively, as shown in
