Installing the SN-DTA
SN-DTA hardware installation consists of the following:
•
Placing the device at the desired installation location (see section
“Placing the SN-DTA”
)
•
Connecting the interface and power cables (see section
“Installing cables”
)
When you finish installing the SN-DTA, go to chapter 4,
“SN-DTA initial configuration”
on page 26.
Placing the SN-DTA
Place the SN-DTA on a desktop or similar sturdy, flat surface that offers easy access to the cables. The unit
should be installed in a dry environment with sufficient space to allow air circulation for cooling.
Note
For proper ventilation, leave at least 2 inches (5 cm) to the left, right, front,
and rear of the unit.
Installing cables
Connect the cables in the following order:
1.
Connect the ISDN terminal to the BRI port (see section
“Connecting the SN-DTA to the
ISDN terminals”
on page 24).
2.
Connect the 10/100Base-T Ethernet WAN (see section
“Connecting the SN-DTA to the IP network”
on
page 24)
3.
Connect the power supply (see section
“Connecting the SN-DTA to the power supply”
on page 25)
Connecting the SN-DTA to the ISDN terminals
The SN-DTA comes with one or two ISDN BRI ports located on the rear panel (see
figure 2
on page 17).
Install the connections as follows:
1. BRI NT:
Connect the BRI NT port of the SN-DTA to the TE port of the ISDN terminal (phone, PBX or
residential S-bus).
2. BRI TE
(SN-DTA/2BIS2V/EUI only)
: Connect the BRI TE port of the SN-DTA to the NT port of the
ISDN device (ISDN NT or PBX NT port).
For details on the BRI port pinout and ISDN cables, refer to
Appendix C, “Cabling”
on page 43 and
Appendix
D, “Port pin-outs”
on page 46.
Connecting the SN-DTA to the IP network
The SN-DTA comes with a 10/100 Base-Tx Ethernet port for connection to an IP network. The Ethernet
WAN interface is factory-configured as a DHCP client, so you must connect the SN-DTA to an IP network
that provides a DHCP server.
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
