This topic provides the basic information you need to connect
the analog-line interface cards installed in the Message Networking system to
the switch. Analog-line interface cards are required on Message Networking systems
using analog.
The Message Networking system supports a maximum of three analog-line interface
cards. Each card has four RJ-11 jacks
on its bracket (see Back view of platform
for reference); each RJ-11 jack supports one voice channel. The
analog-line voice cards are installed from bottom to top beginning
in slot 4 (the first three are blank) and are numbered as follows:
- The first installed board is in slot 4 (fourth slot from the
bottom). The board's RJ-11 jacks support ports 1 through 4, numbered
from right to left, which correspond to channels 0 to 3.
- The second installed board is in slot 5 (fifth slot from the
bottom). The board's RJ-11 jacks support ports 5 through 8, numbered
from right to left, which correspond to channels 4 to 7.
- The third installed board is in slot 6 (sixth slot from the
bottom). The board's RJ-11 jacks support ports 9 through 12, numbered
from right to left, which correspond to channels 8 to 11.
Warning! Damage from electrostatic discharge is possible.
See Protecting against ESD damage for
more information.
To connect the analog-line interface cards to the switch:
- Plug a telephone cable into each RJ-11 jack on the
first card.
- Plug the other end of each telephone cable into the
RJ-11 interface adapter from the switch wall field, circuit pack,
or demarcation connector.
- Repeat steps 1 and 2 for each installed card.
