Connecting the ISDN gateway
5
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.
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.
FFor information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN
gateway LED behavior, on page 2.
Only connect to Ethernet Port A. Ethernet Port B is reserved for future
expansion; do not connect anything to Ethernet Port B.
For D-channel signaling to be established, the ISDN gateway 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.
