the conversion from RJ45 to RJ11 for connection to the back of the DA1 console. This adapter also

PBX Connections
The PBX ports are identical to the DA1 ports (See Figure 16 for exact location). For each PBX port that
is used, one less DA1 port is available. For example if two PBX ports are to be used, only six DA1 ports
are available. A maximum of eight ports are available on the CH1000 system, which are designed to be
connected to analog C.O. ports on the PBX, since the TC1’s provide the necessary loop current (-
48VDC). If the PBX being connected is capable of recognizing caller ID information, then the
corresponding CH1000 DA1 port should be configured as a “Caller ID” phone. This will ensure that all
caller ID information from the CH1000 can be passed along to the PBX phones that are caller ID
capable.
