2-2ULD power limitation
•Maximum 5 watt for 5V
•Maximum 110 watt for 48V
It is recommended that unused ULD ports be the last ports on the 
card.
RS232 connector
The ULD card has an RS232 socket for connection to a PC. The pins 
are the same as for an ELD card (RX TX GND). The RS232 port sup-
ports 19200 bps.
LEDs
There is a LED on the ULD card for the ULD controller. The indica-

2.3.1Avanti telephone set configuration options
Table 2-2 shows the maximum configuration distances for Avanti 
sets wired with 24 AWG wire. These distances are valid when the 
add-on units receive their power from the DIGITAL system’s power 
supply. 
NOTE
When the add-on units are powered by an auxiliary power 
adapter, maximum distance is 1500meters for all configu-
rations, except for the two-wire fully duplex station, which 
has a...

2-5 CoOperate card
The CoOperate card uses a special protocol for PC applications, 
such as TSAPI. 
In PC application mode, data transfer is over the DIGITAL system’s 
D channel. This is the default work mode.
Data is transferred from the PC application via the PC RS232, the 
data card RS232, the U bus D channel, the ULD card, and the sys-
tem LAN toward any DIGITAL system resource address.
