4.7.5 Configuring the remote power supply of S/T0 to S/T3 accesses
UCT-S, UCTS-12 and UCT-C cards have 4 jumpers for configuring the remote power supply of
the S/T0 to S/T3 accesses (one jumper block for each access). The jumpers are plugged into
connectors J29 and J30 located on the front of the UCT-S, UCTS-12 and UCT-C cards. The 4
accesses are arranged vertically on the card. The one at the bottom is the S/T0 access and the
one at the top the S/T3 access. Depending on the position of the jumpers, the S/T0 to S/T3
accesses will be configured as follows:
• No remote power supply
• 48 V power supply (DECT and S sets)
• 40V power supply (option)
