NSTALLATION
Each station is connected to the system through the first 16
pairs of each 66 block. The stations are connected using 2
pairs per station. The first pair is Tip & Ring, and the second
pair is Data.
Note: The order for the Data pair must be observed. If
reversed, a single character will appear on the phones dis-
play indicating the fault.
The station runs can be up to 1,000 ft. Only one phone can be
connected per station port. Each port position is prenumbered
and fixed as indicated in the 66 Block wiring diagram (Figure 1).

ONNECTION
The DSS/BLF Console is connected to a standard Feature
Phone port as described above. Up to 4 consoles can be
installed in a fully configured system. Only one console can be
installed on a port card. Each console is paired with a station
when the console is configured as part of extension program-
ming (Function 3).
ONNECTIONS
The system provides two dedicated analog ports for: FAX,
Modem, Common Ringer, Door Phone, Overhead Paging, or
restricted 2500 phone. A single analog Tip & Ring pair is con-
nected through the first 66 block. Terminal connections are 33 &
34 for the first analog port and 35 & 36 for the second.
Note: These ports are not designed for outside use or for
any use other than as stated above.
Note: The Memory Module is formatted with a proprietary
format– do not attempt to install a non-ESI drive.
Adding or replacing the Memory Module will require that the
system be taken out of service. If the Memory Module must be
replaced, all configuration data and customer recordings will be
lost.
Contact the factory for a replacement Memory Module and
detailed instructions for its installation.
