Step One: Connect Power; Step Two: Connect To Ethernet Port A; Step Three: Connect To The Isdn Ports - Cisco TelePresence ISDN GW 3241 Getting Started

Step one: Connect power

Connect the power connector on the rear of the unit to the power supply using the
supplied power cable. (There is no On/Off switch.)

Step two: Connect to Ethernet Port A

Connect an Ethernet cable from Ethernet Port A to an Ethernet switch (rather than a
hub, to minimize interference from other devices on the network). The Ethernet
port is a 10/100/1000 Mbps auto-sensing connection.
Only connect to Ethernet Port A, as all initial configuration must be done
i
on this port. Do not connect anything to Ethernet Port B.

Step three: Connect to the ISDN ports

The ISDN gateway uses a standard RJ48C ISDN interface for each PRI port. Use a
single straight-through STP patch cable to connect each PRI port on the ISDN
gateway to your ISDN connection.
For information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN
GW 3241 LED behavior, on page 4.
For D-channel signaling to be established, the ISDN gateway must have
i
found and synchronized with the ISDN network clock. In some
installations, you may have to explicitly request your ISDN provider to
enable the network clock before the link will be established.
