User's Manual

Basestations are IP40-compliant wall-mounted transceivers that provide digital radio links to
handsets.
Caution:
Service Interruption
For maximum line length before signal degradation occurs, use UTP
Cat 5 cabling between
the basestation and the shelf or cabinet. If the line length exceeds 100 ohms for the 4610
basestation, an external power supply must be used. The maximum distance when using
external power with UTP Cat 5 cabling is approximately 1.7 km.
The basestation has the following features:
• RJ45 socket connection to a one meter UTP Cat 5 cable
• RJ45 socket connection to an external or local power supply
• Green LED (C4600) or a yellow LED (C4610), indicates synchronization to its DMC8
• One meter UTP Cat 5 cable connected through an RJ45 Connect Box and MDF to an
IPE I/O panel or CS 1000E cabinet I/O panel
Two sources can power the basestation:
• The DMC8 and DMC8-E feeding phantom power over the UTP Cat 5 cable signaling
pairs, connected to (a) in
Figure 14: Basestation on page 26
•
A local power supply, connected to (b) in
Figure 14: Basestation on page 26
Figure 14: Basestation
Basestations connected to a DMC8 or DMC8-E card can use phantom power in some
conditions, and must use local power in other conditions.
An application on the DMC DECT
Manager can enable or disable phantom power.
Note:
The maximum line length for a twelve-channel basestation using phantom power is 1.0 km.
The maximum line length for a six-channel basestation, regardless of power
, or a twelve-
channel basestation using external power, is 1.7 km.
