Step one: Connect power

Connect the power connector on the rear of the device 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

on this port. Do not connect anything to Ethernet Port B.

Step three: Connect to the ISDN ports

The ISDN GW 3241 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 GW

3241 to your ISDN connection.

For information about the behavior of the ISDN port LEDs, see Table 1, ISDN GW

3241 LED behavior, on page 4.

For D-channel signaling to be established, the ISDN GW 3241 must have

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.
