ISDN U Cable
To connect a model 44x or model 54x bridge/router to an ISDN network,
use a Category 5 shielded twisted-pair cable with an RJ-45 connector on
the bridge/router end, and an RJ-11 connector at the wall. This cable
comes with your bridge/router.
Figure 26 shows the pinouts of the ISDN U cable.
